U.S and British troops we

U.S and British troops were equipped to deal with most threats posed by chemical and biological weapons, officials said on March 25, 2003, amid reports Iraq had authorized use of such arms in defense of Baghdad. The troops have NBC (nuclear, biological and chemical) protection suits and respirators and are provided with medication to inject themselves with if they are exposed to threats such as mustard gas and the nerve agents sarin and VX.

M40/42 Protective Mask

Function: Provide respiratory, eye and face protection against chemical and biological agents, radioactive fallout particles, and battlefield contaminants.

Entered Army Service: 1992.

Description: The M40-series protective masks replace the M17-series protective mask as the standard Army field mask, providing improved comfort, fit and protection. The mask consists of a silicone rubber face piece with an in-turned peripheral face seal, binocular rigid eye lens system and elastic head harness. Other features include front and side voicemitters allowing better communication particularly when operating FM communications, drink tube for a drinking capability while being worn, clear and tinted inserts, and a filter canister with NATO standard threads. Because of these features, the mask can be worn continuously for 8 to 12 hours.

The face-mounted canister (gas and aerosol filter) can be worn on either the left or the right cheek, and will withstand a maximum of 15 nerve, choking, and blister agent attacks. It will also withstand a maximum of two blood agent attacks. Biological agents do not degrade the filter.

The M40A1 is the mask issued to dismounted soldiers. It is available in small, medium, and large sizes.

The M42A2 Combat Vehicle Crewman Mask has the same components as the M40A1 with an additional built-in microphone for wire communication. The filter canister is attached to the end of the hose with an adapter for the CPFU connection.

The M45 Protective Mask, issued to Blackhawk crew members, provides protection without the aid of forced ventilation air. It is compatible with aircraft sighting systems and night vision devices. It has close fitting eyepieces, a voicemitter, drink tube, and a low profile filter canister.

The M48 and M49 masks, issued to Apache aviators, are an upgrade of the M43 Type I mask. Their improved blower is chest-mounted, lighter, less bulky, and battery powered.

Several mask improvements have been introduced over the years through Pre-Planned Product Improvement (P3I) Programs, which resulted in M40A1 and M40A2 configurations. The improvements include a quick-doff hood, second skin, canister interoperability (M42A1 only), and voice amplification (M7), new nosecup, two new carriers, and improved vision correction. An additional product improvement was adopted in late 1994, which upgraded the M42 to the M42A2 configuration. This change provides a detachable microphone that improves reliability, simplifies production, and permits field replacements.

M21 Remote Sensing Chemic

Function: Long-range chemical agent detection.

Description: The Remote Sensing Chemical Agent Automatic Alarm is a two-man-portable, automatic scanning, passive infrared sensor which detects nerve and blister agent vapor clouds based on changes in the infrared energy emitted from remote objects, or from a cloud formed by the agent. The RSCAAL is a stand-alone, tripod-mounted, chemical agent overwatch system to be used in a defensive role. It consists of a detector, tripod, M42 remote alarm unit, transit case, power cable assembly, and standard military power source. It will be used for reconnaissance and surveillance missions. It will search areas between friendly and enemy forces for chemical agent vapors, and provide advanced detection and warning of chemical hazards. Where possible, the RSCAAL will be employed in pairs (two reconnaissance teams) so that one RSCAAL can be used in the overwatch position when the other reconnaissance team is moving. The remote warning can be transmitted by two methods: by hardwire to the M42 alarm or by a digital signal transmitted from the M21 via an RS232 cable. The RS232 link will provide a capability to link with the Marine Corps Hazard Warning System/Network.

Chemical Agent Monitor

Function: Post-attack chemical agent surveying/monitoring.

Description: The CAM is a hand-held, man-operated device for monitoring chemical agent contamination on personnel and equipment. The CAM has two controls: an on/off push button switch and a mode select push button switch which selects the blister or nerve-agent mode of operation. The CAM detects vapors of chemical agents by sensing molecular ions of specific mobilities (time of flight) and uses timing and microprocessor techniques to reject inferences. It can detect and discriminate between vapors of nerve and blister agents and display the relative concentration. The Marine CAM also detects and discriminates between other agents.

D-30 122mm Towed Howitzer

Function: 122mm towed howitzer.

Background:Introduced in 1963 as a replacement for the pre-WWII M-30 howitzer, the D-30 122mm howitzer is in service with more than 50 countries and variants are still in production in Russia.

The D-30 fires variable charge, semi-cased, multi-part ammunition. The D-30 is capable of firing a number of projectile types, including HE-fragmentation, illuminating, smoke, leaflet, flechette, and incendiary.

The D-30 is capable of firing a non-rotating, fin stabilized anti-tank HEAT round which gives the gun a limited anti-armor capability. A Rocket Assisted Projectile (RAP) has been fielded which would increase the gun's range from 15,300 meters to 21900 meters.

There are at least two chemical munitions available for the D-30. The Sarin projectile weighs 22.2 kg with 1.3 kg of Sarin agent. The Lewisite projectile weighs 23.1 kg with 3.3 kg of viscous Lewisite agent.

Description: The D-30 has a single axle with a unique three-trail carriage. When limbered for transport, the gun rests on the wheeled axle. Once set up, the gun is suspended on top of the three trail arms which give the gun a 360 degree traverse capability.

The gun's recoil mechanism is housed in an armored box on top of the barrel and there is a small armored shield fitted between the wheels that provides limited protection to the crew. Early versions of the gun were fitted with a multi-baffle muzzle break while later models have been fitted with a double baffle break.

The gun itself is semiautomatic, with a vertically-sliding, wedge-type breechblock. The D-30 can be towed by a truck (Ural-375 or ZIL-131) or armored tractor. It is towed muzzle-first by a large lunette just under the muzzle brake with its trails folded under the barrel.

Alaskan Air Command

The Alaskan Air Command shoulder patch was approved by the OMG on May 20th, 1947. The colors are those of the United States Army Air Forces. The single folded wing represents the Command's ties with the Eleventh Air Force. The "Big Dipper" and "North Star" represent the far northern skies where the Command is operational and stands watch.

On December 18th, 1945 the Eleveth Air Force was redesignated the Alaskan Air Command, maintaining its Headquarters at Elmendorf Field (near Anchorage), Alaska. Initially, the mission of the command was to defend Alaska from enemy air attacks, but later the responsibility for providing sites for early warning communications and for maintaining bases for retalitory attacks was added. In January of 1947, a unified land-sea-air Alaskan Command was established with the United States Air Force acting as executive agent. The Alaskn Air Command arc was worn from December of 1945 until May of 1947 when this shoulder patch was approved.
