M1 Abrams
Function: Main battle tank (MBT).
Description: The M1 has a very angular appearance, reflecting the modular nature of its armor components, with the turret mounted centrally on the hull. The M1 has a crew of four. The driver sits centered in the hull and forward of the turret, while the loader, gunner and tank commander occupy the turret, with the loader situated to the left of the main gun and the gunner and tank commander sitting in tandem on the right side. The driver's hatch has three periscope vision blocks which provide for forward vision. The center vision block may be removed and replaced with an AN/TVS-2 low-light periscope. The engine is mounted in the rear of the vehicle with the exhaust coming out from a louvered grill centrally mounted in the rear of the hull. The M1 utilizes a torsion bar suspension with seven pairs of cast aluminum road wheels and two return rollers. The drive sprocket is to the rear, an idler compensation wheel is located forward, and there is a gap between the first and second pair of road wheels. The M1 has armored skirts running the full length of the track. M1 track is made up of vulcanized rubber blocks (M156 variety) or removable rubber pads (M158.) The turret is also angular in appearance, with the main gun mounted in an exposed mantlet in the center of the turret face. The M68 rifled cannon is equipped with a metal thermal shroud, a bore gas evacuator located two-thirds of the way down on the barrel, and is equipped with a Muzzle Reference System collimator on the muzzle itself. The M240 coaxial (COAX) machine gun is located to the right of the main gun, with the flash tube extending through the main gun mantlet. The Gunner's Auxiliary Sight (GAS) aperture is located below the COAX flash tube on the right side of the main gun. The M1 has two turret access hatched, mounted side by side, in the middle of the turret roof. The loader's hatch, located on the left side, is equipped with a pintle mounted M240 7.62mm machine gun. The hatch itself is equipped with a single vision periscope on a rotating base. When not in use, the drivers AN/TVS-2 sight may be used in the loader's hatch vision block. The tank commander's hatch is ringed by vision periscopes and the Commander's Weapon Station cupola is equipped with an M2 HB caliber .50 machine gun. The M2 may be fired while the commander is "buttoned up" but the commander must be exposed to reload the weapon. The CWS can be reconfigured to fire an M240 as a replacement weapon. The Gunner's Primary Sight (GPS) is located forward of the commander's cupola. The GPS is housed in an armored box with hinged doors shielding the optics when not in use. The GPS is divided into two halves; a clear glass window for normal daylight viewing and an IR transparent Germanium coated window for the thermal imaging sight. The Laser Range Finder (LRF) is fired through the daylight window. There are individual sponson boxes located on either side of the turret for equipment storage. These boxes are approximately three feet (1m) long and are bracketed by a three-rail cargo rack which runs the length of the turret side. The smoke grenade launchers are located on either side of the turret, forward of the turret sponson boxes. There are mounting points for two radio antennae, one on either side of the turret rear, and the cross wind sensor is mounted upright in the center of the turret rear. A cargo bustle rack is mounted on the rear of the turret and runs the length of the turret rear (in early production M1s this rack was omitted and a fabric cargo net mounted in it's place. An Auxiliary Power Unit (APU) may be mounted in the turret bustle rack or on the rear of the hull.
History: Fielded in February 1980, the M1 General Abrams main battle tank revolutionized armored warfare. Incorporating an advanced shoot-on-the-move fire control system, a thermal imaging sight, a 1500 horsepower gas turbine engine and an advanced armor design similar to the Chobham armor developed in England, the M1 was the most lethal armored vehicle in the world. Conceived in 1971 as a replacement for the aging M60 tank, which was itself an extension of the 1050s era M 47/48 program, the M1 was going to be of a completely new design, establishing a new family of American main battle tanks. Providing the Abrams with a true shoot on the move capability, the fire control system automatically corrects for range, turret slew (motion) rate, crosswind, and tank axial tilt (cant). In addition, the gunner manually enters ammunition or weapon type, air and ammunition temperatures, barometric pressure, and gun tube wear, while range is instantly calculated by a Nd:YAG (Neodymium doped Yttrium Aluminum Garnet) near infrared laser rangefinder. Lastly, the gunner can compensate for gun tube deformation (caused either by heat generated from firing the cannon or atmospheric changes) through the use of a muzzle reference system, which allows for a rapid realignment of the cannon and the gunner's primary sight.
The Chobham armor built into the M1 represents a veritable leap in armor technology. Composed of layers of metal, ceramics, and spaces, this new armor is far superior to RHA (Rolled Homogeneous Armor) in defeating kinetic and chemical energy weapons. To increase crew safety and survivability, all of the M1's ammunition is stored in armored compartments which are designed vent dangerous gasses and fragments away from the crew in the event of an ammunition explosion. The crew and engine compartments are equipped with an automatic fire suppression system, utilizing numerous fire detection sensors and pressurized Halon gas, which can react to and suppress a compartment fire in less than 250 ms.
To survive on the NBC (Nuclear, Biological, Chemical) battlefield the M1 is also equipped with both an over pressurization and air sterilization system which will protect the crew from these hazards and allow them to continue combat operations without having to wear protective overgarments and masks while buttoned up inside the vehicle.
Lastly, the M1 was the first land combat vehicle to utilize a gas turbine multi fuel engine, which offers a higher power to weight ratio than any other contemporary tank power plant and gives the Abrams unparalleled tactical mobility and cross country speed. The M1 retains the M68 105mm rifled cannon used on the M60 series tanks, which was originally based on the British M7 105mm cannon design, and is capable of firing both rifled and fin stabilized ammunition. In addition, the M1 is equipped with two M240 7.62mm machine guns; one mounted coaxially with the main gun and fired by gunner, and the other mounted at the loader's station. The Commanders Weapon Station (CWS) is equipped with an M2 heavy barrel Caliber .50 machine gun. The CWS can be reconfigured to fire the M240 machine gun as a substitute.) The M1 is equipped with a pair of M250 red phosphorus smoke grenade launchers and is capable of generating smoke by injecting diesel fuel into the engine exhaust.
Originally designated the XM1, the first production model was designated the M1, of which 2,374 were built between 1982 and 1985. In 1984 the M1IP (Improved Product) was introduced, which was outwardly identical to the M1, but which incorporated a number of internal automotive, electronic and armor improvements. Production of the M1IP was halted at 84 tanks in 1986, when the Lima and Detroit tank plants were reconfigured to produce the up-gunned 120mm M1A1. In 1992 a study was conducted evaluating the feasibility of upgrading the Army's fleet of M1s to M1A2 SEP (Standard Equipment Package) standard and low rate production was approved in 1994. Since then the Army had agreed to convert 547 M1s to the M1A2 SEP standard.

Army Valorous Unit Award
VALOROUS UNIT AWARD
1. Description: The Valorous Unit Award worn to represent award of the Valorous Unit Award is 1 7/16 inches wide and 9/16 inch in height. The emblem consists of a 1/16 inch wide Gold frame with laurel leaves which encloses a ribbon of the pattern of the Silver Star Medal ribbon centered on a Red ribbon. The stripe dimensions of the ribbon are: 3/8 inch Old Glory Red 67156; 1/16 inch Ultramarine Blue 67118; 1/64 inch White 67101; 3/32 inch Ultramarine Blue; 3/32 inch White; center 3/32 inch Old Glory Red; 3/32 inch White; 3/32 inch Ultramarine Blue; 1/64 inch White; 1/16 inch Ultramarine Blue; and 3/8 inch Old Glory Red. The streamers are the same pattern as the Silver Star Medal ribbon.
2. Criteria: The Valorous Unit Award is to be awarded to units of the Armed Forces of the United States for extraordinary heroism in action against an armed enemy of the United States while engaged in military operations involving conflict with an opposing foreign force or while serving with friendly foreign forces engaged in an armed conflict against an opposing armed force in which the United States is not a belligerent part for actions occurring on or after 3 August 1963. The Valorous Unit Award requires a lesser degree of gallantry, determination, and esprit de corps than that required for the Presidential Unit Citation. Nevertheless, the unit must have performed with marked distinction under difficult and hazardous conditions in accomplishing its mission so as to set it apart from the other units participating in the same conflict. The degree of heroism required is the same as that which would warrant award of the Silver Star to an individual. Extended periods of combat duty or participation in a large number of operational missions, either ground or air, is not sufficient. This award will normally be earned by units that have participated in single or successive actions covering relatively brief time spans. It is not reasonable to presume that entire units can sustain Silver Star performance for extended time periods under the most unusual circumstances. Only on rare occasions will a unit larger than a battalion qualify for this award.
3. Components: The current components of the Valorous Unit Award are the emblems awarded to members of the unit and the streamer for display on the unit flag/guidon.
a. Valorous Unit Award: MIL-D-3943/32 (frame) and MIL-R-11589/154 (ribbon). NSN-8455-00-964-4296.
b. Streamer: MIL-S-14650/5. Manual requisition in accordance with Chapter 9, Army Regulation (AR) 840-10.
4. Background:
a. As a result of a request from the Commander, USMACV, to expand the scope of the Meritorious Unit Commendation to include acts of valor, a review of the unit awards program was conducted in 1965. The study concluded that a gap existed in the awards program. The Distinguished Unit Citation was awarded for gallantry in action for heroism that would warrant the Distinguished Service Cross to an individual. There was no lesser unit award for heroism. Based on the study, a recommendation was submitted to expand the scope of the Meritorious Unit Commendation to include acts of heroism. The recommendation was disapproved by the DCSPER and in a memorandum to the CSA, dated 7 January 1966, the DCSPER recommended a Valorous Unit Award be adopted to signify unit gallantry in combat to a degree equivalent to that required for award of a Silver Star to an individual. The recommendation with proposed design was approved by the Chief of Staff, Army, on 12 January 1966.
b. The emblem is worn by all members of a cited organization and is considered an individual decoration for persons in connection with the cited acts and may be worn whether or not they continue as members of the organization. Other personnel may wear this decoration while serving with an organization to indicate the unit has been awarded the Valorous Unit Award.
c. Order of precedence and wear policy for unit awards is contained in AR 670-1. Policy for awards, approving authority, and supply of the unit award emblem is contained in AR 600-8-22. The policy for display of unit awards on guidons and flags and supply of streamers is contained in AR 840-10.

BTR-70 APC
Function: Soviet 1970-era wheeled APC.
Background: Introduced in 1978 as a replacement to the BTR-60, The BTR-70 is very similar externally to the older vehicle, as many if the improvements made to the vehicle are internal.
The BTR-70 uses the standard Warsaw Pact APC weapons turret equipped with one KPV 14.5mm machine gun and one PKT 7.62mm machine gun. As with the BTR-60, power is supplied to all eight wheels by means of a unique twin engine/transmission arrangement. The BTR-70's power plants, however, have been upgraded to two 120hp gasoline engines. The gearbox arrangement, however, remains unchanged; one supplies power to the 1st and 3rd axles and the other supplies power to the 2nd and 4th axles.
The BTR-70 is also fully amphibious and does not require any preparation time. Steering, both on land and in the water, is provided by the forward two axles, which are also power assisted. Water propulsion is provided by a single rear mounted water jet.
Though replaced by the BTR-80 in the early eighties, the BTR-70 continues to serve in many armies world-wide, including most former Warsaw Pact as well as many Middle Eastern, African, and Asian countries.
Description: The BTR-70 an all-wheeled 8x8 fully amphibious armored personnel carrier. The boat shaped vehicle is divided up into three sections: crew compartment, personnel compartment, and engine compartment. In the case of the BTR-70 the hull has been lengthened somewhat and the axles now have a paired appearance, with a distinctive gap between the second and third axles.
The BTR-70 may be readily distinguished from the 60 and 80 series by the presence of a single, large, curved "caterpillar" insulated exhaust located on either side of the hull rear. In addition the amphibious operations trim vane has been moved from underneath the nose of the vehicle, BTR-60 series, to on top of the nose, just forward of the driver's station.
The BTR-70 is equipped with the standard Warsaw Pact APC turret. The small, one man turret is mounted over the second axle and contains one KPV 14.5mm machine gun and one PKT 7.62mm machine gun.
The personnel compartment can be accessed by a triangular doorway located between the second and third axles. The three infantry mounting steps and the three additional mounting rails located on the hull above the steps, present on the BTR-60, have been eleminated. The large personnel compartment access hatches located on each side of the hull have also been eliminated and replaced with three firing ports.

T-62 MBT
Function: Soviet front line MBT during the 1960s.
Background: The T-62 was introduced in 1961 to replace the T-55 as a Soviet front line main battle tank. In many respects, the T-62 represents a product improvement upgrade of the T-55; the T-62 uses the same 580hp V-12 diesel engine, the track, suspension, and drive train arrangement are essentially the same. The initial-run T-62 also shared the same NBC protection system and active infrared gunner's sight as the T-55. The T-62 uses the same fording components as the T-55 and is capable of fording to a depth of 1.4m without modification and to 5.5m with the snorkel kit. The T-62 is capable of producing onboard smoke by injecting vaporized diesel fuel directly onto the engine exhaust.
The T-62's real improvement lay in its 115mm smoothbore, high velocity cannon. With a muzzle velocity of over 1,600m/s, the T-62 has a nearly flat trajectory through its entire effective range, making the gun very accurate. Later production models incorporate a true NBC filtration/over-pressurization system, thus eliminating the need for the crew to wear protective masks while inside the tank, as well as a passive IR gunner's sight which eliminated the need for active infrared search lights which would reveal the location of the illuminating tank.
Although the Soviet Union ceased production of the T-62 in 1975, the T-62 still remains in front-line service with a number of countries world-wide.
Description: The T-62 is similar in appearance to the T-55. The T-62 uses the same "live track" design as the T-55. There are 5 large cast road wheels, with a distinctive gap between the third and fourth and the fourth and fifth road wheels. The track is all steel, the idler wheel is to the front, the drive sprocket is to the rear and there are no return rollers.
The turret is more egg or pear-shaped than dome-shaped, as with the T-55, and the attached infantry hand rails, if present, are both curved, as opposed to the straight and curved rails on the T-55.
The main IR searchlight is mounted on top of the turret, to the right of the main gun, as with the T-55, with one secondary searchlight mounted below the main light to the right of the gun and one mounted on the commander's cupola on the left side of the turret.
The 115mm smoothbore cannon uses the same trunion arrangement as with the T-55, substituting an armored mantlet for a canvas weather-resistant cover. The cannon has a bore evacuator mounted one third of the way down the gun tube and may be equipped with a thermal sleeve.
The T-62 employs the same coaxial PKT-T 7.62mm machine gun as the T-55 and is mounted to the right of the main gun. The 12.7mm DShK anti-aircraft machine gun is mounted at the loader's station.
As with the T-55, the T-62 does not use armored fuel cells. Instead, the fuel is stored in exposed tanks on the track fenders. The engine exhaust is expelled out the left rear side of the hull. Auxiliary fuel tanks may be attached to the rear of the hull.

Four (Loader, driver, gunner, Tank Commander)
Armament:
Main:
115-mm smoothbore gun, 2A20
AT-10 Sheksna Cannon launched ATGM
Secondary:
One 12.7mm DShK anti-aircraft machine gun (loader's station)
One 7.62mm PKT-T coaxial machine gun
Ammunition:
40 main gun rounds, typically 12 HVAPFSDS rounds, 6 HEAT rounds, and 22 HE rounds
Sensors:
Drozd APS (T-62D)
Introduction Date:
1961
Variants:
T-62A: First production model of the T-62. Incorporates the 12.7-mm DShK anti-aircraft machine gun, which is mounted at the loader's station, and an improved two-axis gun stabilization system that gives the gunner limited a shoot-on-the-move capability.
T-62K: Command variant. In addition to having increased radio capabilities, the "K" model also possesses an inertial land navigation system. Using a gyroscopic compass and distance calculator this navigation system allows the commander to plot his location from a known point as well as display direction and distance to a plotted point.
T-62M: The T-62M is essentially an "A" model upgraded to the T-55M standard. Added the Soviet made Volna fire control system (dual-axis stabilization, laser range finder) as well as a cannon launched ATGM (AT-10 Sheksna.) Upgrades in armor protection include the 180o "bra" armor belt on the front half of the turret, track side skirts, and smoke grenade launchers.
T-62M1: "M" model without the through cannon ATGM capability. "-1" variants have replaced their standard power plant with the 780hp V-46 12 cylinder diesel engine from T-72 MBT.
T-62D: Variant with the Drozd APS in place of Explosive Reactive Armor (ERA.) Developed by the Soviet Union in 1977, the Drozd system was designed as an active defense against ATGMs and anti-tank grenades. The system was based on a number of millimeter-wave radar transceivers situated around the turret. The radar sensors would detect the approach of an ATGM and fire off short-ranged fragmentation rockets that were intended to shred the incoming missile. To prevent accidental discharge, the system was equipped with a filter to react only to objects flying at characteristic ATGM speeds. The four-barreled launchers were located on the forward part of the turret and only provided protection for the front 60? portion of the turret. To change the covered arc of coverage the crew would have to rotate the turret and orient the coverage cone on the threat.
T-62MK: Command variant of the T-62M.
T-62MV: "M" variant with ERA (either Kontakt or Kontakt-5 second generation) in place of the bra armor.

T-55 MBT
Function: Soviet front line MBT during the 1950s.
Background: Introduced in 1949, the T-54/55 is in service with more countries world-wide and in greater numbers than any other tank manufactured since World War II. The first new tank of the post-World War II Soviet Union, the T-54/55 can trace its lineage back to the IS series Stalin heavy tanks and the revolutionary T-34 medium tanks.
The T-54 entered production in the Soviet Union in 1947, and was fielded with Soviet ground forces in 1949. By 1958, the T-54 had undergone a number of improvements and modifications and was re-designated the T-55. The T-55 represents an evolution of the T-54 rather than a completely new design.
The T-55 was produced by the Soviet Union through 1981. In addition, the T-55 was also produced in China (where it was designated the Type 59), Czechoslovakia, and Poland. The T-55 is capable of fording to a depth of 1.4m without modification and to 5.5m with the addition of a snorkel kit. The T-55 is capable of producing onboard smoke by injecting vaporized diesel fuel directly onto the engine exhaust.
Though time and technology have rendered the T-55 obsolete as a front-line main battle tank, large numbers of 54/55s remain in service with militaries world-wide. The T-55 saw service in Hungary in 1956, Czechoslovakia in 1968, and in Syria in 1970. In addition, it was the main battle tank used by the Arab forces during the 1967 and 1973 Arab-Israeli wars. During the 1970s the T-54/55 also saw extensive use during the border wars in Africa. Since so many T-54/55s remain in service, many countries, such as Israel, Pakistan, and India offer upgrade packages to rebuild existing tanks using more modern, and in many cases Western, fire control components, thus extending their usable life even further.
There are currently seven production models of the T-54/55, and more than a dozen variants.
Description: The T-54/55 tank follows a conventional layout, with a dome-shaped turret centrally located on the hull and the engine mounted in the rear. The 54/55 has a crew of four; driver (located in the left hand side of the hull, forward of the turret) loader (right hand side of the turret) tank commander and gunner (both located on the left side of the turret.
The T-54/55 can be identified by the distinct gap between the first and second of its five large cast road wheels. The 54/55 uses steel track (this may be substituted for padded track in modified versions), a torsion bar "live track" suspension with no return rollers and a rear mounted drive sprocket. The T-55 does not use armored fuel cells. Instead, the fuel is stored in exposed tanks on the track fenders. The engine exhaust is expelled out the left rear side of the hull.
The 100mm cannon is centrally mounted in the turret. The cannon trunions are not protected by an armored mantlet, but rather a canvas sleeve that protects the mechanism from the elements. There is no fume extractor on the T-54, while the T-55 has a bore evacuator mounted on the muzzle of the gun.
There are two hatches on the top of the turret (loader's and tank commanders.) Both hatches open forward. In the T-54 the 12.7mm DShK AA MG is mounted in the commander's station; on the T-55 ("A" version and beyond) the machine gun is located in the loader's position.
Two infantry support rails (one straight, one curved) are affixed to the turret sides. These may be removed to accommodate ERA, APS or applique armor packages. If present the main IR searchlight will be mounted on top of the turret (to the left of the gun.) An additional searchlight may be mounted on the commander's hatch. If present, the laser rangefinder will be mounted externally on the top of the main gun itself.
Because the T-55 does not use synchronized optics for the main gun, another identifying characteristic of the T-55 is the large sighting oval on the left hand side of the turret next to the gun mantlet. The aperture on the right hand side of the turret is the firing port for the coaxial PKT-T machine gun.

Variants:
T-54A: The initial production model of the T-54 tank. It has a bore evacuator at the end of the barrel for the 100mm gun, a stabilization system for the main gun (in the vertical plane only) and deep fording equipment. The turret is also equipped with a coaxially mounted PKT-T 7.62mm machine gun, and the tank commander's station is equipped with a 12.7mm DShK anti-aircraft machine gun.
T-54AK: Command tank variant of the T-54. The AK variant is a T-54A with long-range radio transmitting capability. The Polish model is the T-54AD.
T-54B: Equipped with active infra-red sights, giving the tank a limited night time fighting ability.
T-55: Essentially an upgraded T-54. The T-55 incorporates a more powerful water-cooled V-12 diesel engine. The cruising range has also been increased from 400km to 500km (range can be increased to 715km with the addition of auxiliary fuel tanks mounted on the rear of the hull.) The T-55 uses a new turret design, which incorporates an improve ventilation design and hatch design. The initial production T-55 did not have the 12.7mm DShK AA MG.
T-55A: Incorporates a new anti-radiation lining in the turret as well as a Nuclear Biological Chemical (NBC) air filtration system. The T-55A Model 1970 saw the re-introduction of the 12.7mm DShK AA MG, though it is now mounted at the loader's station.
T-55M: Added the Soviet made Volna fire control system (dual axis stabilization, laser range finder) as well as a cannon launched ATGM (AT-10 Sheksna.) Upgrades in armor protection included the addition of side skirts on the track, applique armor, as well as smoke grenade launchers. T-54s upgraded to the "M" standard were designated the T-54M
T-55AM: Adds an armor band around the front of turret for 180? coverage (similar to the T-72B "Dolly Parton" variant.)
T-55AMV: Substitutes Explosive Reactive Armor for the "bra" armor belt of the "AM" variant. Some variants have replaced the standard T-55 V-12 diesel with the 780hp V-46 12 cylinder diesel engine from T-72 MBT.
T-55AM2B: Czech version of T-55AMV with Czech built Kladivo fire control system.
T-55AM2: Variant of the T-55AM that incorporates all of the upgrades of the "M" and "AM" except for the Volna fire control system and cannon launched AT-10 ATGM.
T-55AM2P: Polish version of T-55AMV. Equipped with the Polish built Merida fire control system.
T-55AMD: T-55AMV incorporating the Drozd Active Protection System (APS) instead of ERA. Developed by the Soviet Union in 1977, the Drozd system was designed as an active defense against ATGMs and anti-tank grenades. The system was based on a number of millimeter-wave radar transceivers situated around the turret. The radar sensors would detect the approach of an ATGM and fire off short-ranged fragmentation rockets that were intended to shred the incoming missile. To prevent accidental discharge, the system was equipped with a filter to react only to objects flying at characteristic ATGM speeds. The four-barreled launchers were located on the forward part of the turret and only provided protection for the front 60? portion of the turret. To change the covered arc of coverage the crew would have to rotate the turret and orient the coverage cone on the threat.

Newburgh, May 1783
After the British rout from Lexington, a loosely organized New England army of volunteers and militia laid siege to Boston. The British commander, Sir Thomas Gage, determined to gain more elbowroom by seizing the Charlestown peninsula. Learning of Gage's plans, the Massachusetts Committee of Safety recommended the occupation of Bunker Hill, a commanding height near the neck of the Charlestown peninsula. But a working party of 1,200 Americans, sent out on the night of 16-17 June 1775, instead fortified Breed's Hill, a lower height nearer Boston.
When the British awoke next morning, they saw a fortification with walls six feet high astride Breed's Hill. Determined to take the barrier by assault, a force of 2,200 Redcoats under Sir William Howe landed on the Charlestown shore in early afternoon 17 June, and launched a well-planned three-pronged attack. The Americans, who had been reinforced during the morning, repulsed the British assault with devastating musket fire. Howe had to resort to frontal attacks on the American redoubt to avoid a costly defeat of British arms. After enduring two volleys that tore huge gaps in their lines, the Redcoats converged on the American forces in a final three-column attack. The Patriots, running out of ammunition, used their muskets as clubs against the British bayonets. Colonel William Prescott, seeing the damage wrought by the Regulars, ordered his men to "twitch their guns away." The homespun-clad Americans contested every inch of ground, but finally were forced to retreat from t he peninsula.
Bunker Hill gave its name to the battle fought on Breed's Hill. For the British it was a Pyrrhic victory, their losses amounting to over 40 percent of the forces engaged. A force of New England townsmen and farmers had proven its ability to fight on equal terms with British Regulars when entrenched in a fortified position.
The ceremony, however, symbolized much more than recognition of two brave men. It represented the climax of the molding of a citizen army of volunteers and militia into a force that had fought on equal terms with one of the world's best armies, and in doing so, had played a vital role securing freedom and independence for themselves and their fellow citizens.

Resistance Cross
Resistance Cross
When the Netherlands was liberated in May 1945, the Dutch government in London had succeeded in developing a good and balanced system of both military and civilian decorations. Apart from the already existing Military Order of William, new decorations aroused like the Bronze Lion, the Bronze Cross, the Cross of Merit and the Flyers Cross. Deeds of courage could be awarded in a very efficient way. However there was not a good decoration to award people of the resistance organisations. In surrounding countries the government had already succeeded in filling this gap. The Dutch government also tried to achieve this goal. Because of the fact that there could not be found an agreement whether deeds of resistance could be awarded with an existing Military Decoration or there was to be developed a special decoration, time passed on.
Especially within the Dutch Resistance there was a forceful movement against the decoration of resistance deeds. During war, every deed of resistance was thought to be equal to any other. However, other countries did decorate Dutch resistance people. A significant number of Dutch people were awarded decorations like the British King?s Medal for Courage in the Cause of Freedom and the American Medal of Freedom for their resistance work. Strengthened by this the Dutch government pushed on. Apart from that it was a personal wish of Queen Wilhelmina of the Netherlands that resistance work should be decorated.
A special commission was formed to seek the possibilities. This Raad voor Onderscheiding en Eerbetoon ( Council for Decoration and Honour), with Prof. Ir. W. Schemerhorn, dr. L.J.M. Beel, J.M. de Booy, mr. E.N. van Kleffens, Prof. Dr. P. Lieftinck, mr. J. Meynen and General-major mr. H.J. Kruls, first asked the Grote Adviescommissie der Illegaliteit ( Great Committee of the Resistance, GAC) for advise on the matter. It should not be any surprise that this committee advised negative. On the other hand, another organisation of the former resistance, the former members of the Binnenlandse Strijdkrachten (Inland Forces B.S) that was formed at the end of the war by combining the forces of the many weaponed resistance groups in the Netherlands, did announce they were positive about decorating deeds of resistance. Finally the Dutch government took its own decision and on November 28th 1945, the order was given to the Rijksmunt to develop a new medal. Finally the choice was made for the Resistance Cross which was developed by L.O. Wenckenbach.
By Royal Decree of May 3rd 1946 the Resistance Cross was finally instituted. The formal disruption was: ?The Bronze decoration of the Resistance Cross resembled a four armed cross, imbedded on a star of flames and covered with the Royal Crown. On the front one can find St. Joris fighting the dragon. On the arms of the cross are engraved the words ?Trouw tot in den dood?. On the obverse one can find a flaming sword wit two broken chains?, all according to article 4 of the Royal Decree. The ribbon is coloured in Crimson Red with two golden orange lines.
Although presenting the decoration to a living person, a compromise was found with the opposing people of the former Dutch Resistance and the decoration was only given to people that already died. Only once this promise was broken, when on July 19th 1946 a Resistance Cross was awarded by Queen Wilhelmina to Gerard Tieman, living in the Blindeninstituut in Bussum (Home for the Blind).
The first Resistance Crosses were awarded by Royal Decree of May 7th 1946 and were given to the relatives on May 9th of the same year. The group of people that was awarded was very carefully chosen from all the different groups of the Dutch Resistance movement. Very high rules were used to make the decoration one of the highest in ranking in the Dutch system, coming only second after the highest, the Military Order of William. The Resistance Cross was also awarded to foreign people for their part in the Dutch Resistance network. On October 24h 1946 the first ?foreign? decorations were awarded to Belgian Resistance Fighters.
One remarkable Resistance Cross must not be forgotten. To commemorate the millions of Jews that were killed during the Second World War, there was to be build a monument in New York. Mr. E.N. Kleffens, then Dutch Ambassador in the United States was asked to be a member of the Commission of Recommendation for the monument to be called the ?American Memorial to six million martyred Jews and the Heroes of the Warsaw Ghetto Battle?. Kleffens was asked to present a decoration as forms of publicity for the monument. By his doing a Royal Decree no.4 was announced on October 17th 1947, giving a Resistance Cross to the ?Unknown Jewish Soldier of the Warsaw Ghetto who died for the Freedom of all People?. Although the monument never was finished, on the place of the monument in the Riverside Park a memorial stone was erected with the lines: ?This is the site for the American Memorial to the heroes of the Warsaw Ghetto Battle April-May 1943 and to the six million Jews of Europe martyred in the cause of human liberty?.

Royal Hohenzollern House
Royal Hohenzollern House Order, as its name implies, was not so much a Prussian order as an order of the Prussian ruling family, the Hohenzollerns. Nonetheless, this order earned an important place in the heirarchy of Prussian military awards of the First World War. The knight's cross of this order became a bridge to the considerable gap between the Iron Cross, first class, and the Pour le Merite for recognizing heroism., while the Crown Order and Red Eagle (logical choices) remained fairly exclusive.
There was also a "member's cross" of the order which was available to non-commissioned officers, but was rarely awarded. When awarded for duty in a combat unit or for combat operations, the decoration had swords between the arms of the cross. There were over 8,000 awards made during World War I, the vast majority of them knight's crosses.

Epinal American Cemetery
The World War II Epinal American Cemetery and Memorial is located approximately four miles southeast of Epinal (Vosges), France on Road D-157 in the village of Dinoze-Quequement. It can be reached by automobile via toll Autoroute A-4 eastward to the Nancy Exit. Take Highway N-57 and exit at Arches-Dinoze. Rail service is available from Gare de l'Est, Paris via Nancy, where it may be necessary to change trains. The journey by train takes about five hours. Air travel is available from Paris to the Epinal-Mirecourt Airport. Travel by air takes forty-five minutes. Adequate hotel accommodations and taxi service can be found in Epinal and vicinity.
The cemetery, forty-eight acres in extent, is located on a plateau one hundred feet above the Moselle River in the foothills of the Vosges Mountains. It contains the graves of 5,255 American military Dead. It was established in October 1944 by the 46th Quartermaster Graves Registration Company of the U.S. Seventh Army as it drove northward from southern France through the Rhone Valley into Germany. The cemetery became the repository for the fatalities in the bitter fighting through the Heasbourg Gap during the winter of 1944-45.
The memorial, a rectangular structure with two large bas-relief panels, consist of a chapel, portico and museum room with its mosaic operations map. On the walls of the Court of Honor, which surround the memorial, are inscribed the names of 424 Americans who gave their lives in the service of their country and who rest in unknown graves.
Stretching northward is a wide tree-lined mall that separates two large burial plots. At the northern end of the mall the circular flagpole plaza forms an overlook affording a view of a wide sweep of the Moselle valley.
On May 12, 1958, thirteen caskets draped with American flags were placed side by side at the memorial at Epinal American Cemetery. Each casket contained the remains of one World War II "Unknown" American serviceman; one from each of the thirteen permanent American military cemeteries in the European Theater of Operations. In a solemn ceremony, General Edward J. O'Neill, Commanding General of the U.S. Army Communication Zone, Europe, selected the "Unknown" to represent the European Theater. It was flown to Naples, Italy and placed with "Unknowns" from the Atlantic and Pacific Theaters of Operation aboard the USS Blandy for transportation to Washington, DC for final selection of the "Unknown" from World War II. On Memorial Day, 1958, this "Unknown" was buried alongside the "Unknown" from World War I at the Tomb of the Unknown Soldier at Arlington National Cemetery.
The Epinal cemetery is open daily to the public from 9:00 am to 5:00 pm except December 25 and January 1. It is open on host country holidays. When the cemetery is open to the public, a staff member is on duty in the Visitors? Building to answer questions and escort relatives to grave and memorial sites.
