M1A2
Function: Main battle tank (MBT).
Description: The M1A2 is externally very similar in appearance to the M1A1 with the exception of the redesigned Commander's Weapon Station (CWS) and the Commander's Independent Thermal Viewer (CITV.) The powered cupola has been replaced with a manually operated anti aircraft pintle mount, which cannot be fired while the commander is "buttoned up." In addition, the hatch has been enlarged and the vision blocks have been enlarged, improving visibility. The CITV is mounted in an armored rotating cylinder on the turret access plate forward of the Loader's station. The CITV is tall enough to limit the effectiveness of the loader's M240 machine gun through its forward arc of fire.
History: Approved for production in 1990, the M1A2 represents a technological improvement of the basic M1A1 design. Outwardly similar in appearance to the M1A1, the most notable exterior changes on the M1A2 are the redesigned Commander's Weapon Station (CWS) and the addition of a Commander's Independent Thermal Viewer) on the left side of the turret forward of the loader's hatch. Internally, however, the M1A2 has been radically redesigned to take advantage of newer technology. Most notable of these improvements is the addition of the Inter-Vehicle Information System (IVIS.) The IVIS system allows for the automatic and continual exchange of information between vehicles. By incorporating information provided by an on board Position/Navigation (POSNAV) system, unit commander's can track the location and progress of subordinate elements automatically, without tasking vehicle crews. In addition enemy positions can be identified, plotted and disseminated, while reports and artillery requests can be automatically formatted, transmitted, and processed. Lastly, map graphic control measures and operational orders can be rapidly distributed via the IVIS system. To ensure information security, all IVIS data transmissions are routed through the M1A2's SINCGARS radio system. Improving on the "hunter-killer" tank commander-gunner target hand off method pioneered on the German Leopard II, the M1A2 takes this a step further by providing the Tank Commander with an independent thermal sight. This CITV sight allows the commander to independently scan for targets in all weather conditions and through battlefield obscurants. In addition to IVIS and the CITV, the M1A2 incorporates a number of additional electronic upgrades. Power distribution throughout the tank has been improved, relying on multiple bus paths so that in the event one conduit is damaged, power may still be delivered to a component via an alternate path. The driver's instrument display has been upgraded to a more detailed digital display and the Gunner's Primary Sight has been stabilized in two axes for increased accuracy.
Approved for implementation in 1995, the M1A2 SEP (System Enhancement Package) is a technology upgrade and standardization program, whereby the Army's fleet of M1s and M1A2s will all be brought to a common standard. Most notable among the modifications will be the introduction of a standard under armor auxiliary power unit and the addition a crew compartment air conditioning and cooling unit. Other modifications within the vehicle will include upgrades to the IVIS system (color display, full size keyboard, digital mapping and graphics generation capability, and voice recognition capabilities), upgrades to the Gunner's Primary Sight assembly, and improvement in the tank's intercom and radio communications systems. Production of the M1A2 was halted after the initial run of 627 vehicles. As part of the fleet upgrade program, 547 of the Army's current inventory of M1s are being upgraded to M1A2 SEP standards, which will require the complete remanufacturing of the turret, while the current fleet of M1A2s will undergo a retrofit to bring them up to SEP standards.
The M1A2 is currently available for export, albeit with a different armor composition and communications package. Saudi Arabia has purchased 312 M1A2s, equipped with British Jaguar radios, and Kuwait has purchased 218 similarly equipped M1A2s.

Iron Cross
Iron Cross. Originally created in 1813 by King Fredrick III during Prussia's period of 'blood and iron' -- their struggle for survival against Napoleon. The award was to supersede all other bravery awards and only during times of war. The Iron Cross was re-issued during the Franco-Prussina war (1870-71). The 1914 Iron Cross was established in three classes: second class, first class (shown above), and Grand Cross. The Grand Cross was of the same design, but physically larger and worn at the neck. In 1916, the grand cross was augmented with a breast star, which was bestowed upon only one recipient - Field Marshall Von Hindenburg. The second class and Grand Cross are suspended from a black and white ribbon, while the first class is a pinback badge worn on the left side of the uniform. The second class cross was usually only worn in dress uniform - at all other times it was represented by its ribbon looped through the second buttonhole of the tunic. There were approximately 218,000 awards of the first class during WWI, and over 5,000,000 of the second class. There were only five recipients of the Grand Cross, including Hindenburg, and of course, the Kaiser himself.
