August 29, 2008:The U.S. Army has ordered 62 more M1128 Stryker Mobile Gun System (MGS) vehicles [VIDEO], at a cost of about $5.3 million each.The vehicle has a 105mm gun turret mounted on it, as well as a 12.7mm and 7.62mm machine-gun. It weighs 19 tons. The vehicle has a crew of three, and carries 18 rounds for the 105mm gun, 400 for the 12.7mm machine-gun, and 3,400 for the 7.62mm machine-gun.

The army sent the first of its Stryker Mobile Gun Systems to Iraq last year [PHOTO]. The gun has an automatic loader. The gun is stabilized, and can be fired on the move. Once in Iraq, the gun performed well, providing accurate and effective firepower when needed. There were some problems, however.

In order to get all the gear needed for a 105mm gun into a Stryker vehicle, there was no room for air conditioning. In summertime Iraq, this presents a problem. The three man crew had to be equipped with something that would prevent heat stroke. The solution was the "air conditioned suit" of legend, and science fiction. Back in 2003, after three years of development, the U.S. Army put into service the "Air Warrior Microclimate Cooling System." It's a vest full of tiny tubes that carry cooled water (with some non-toxic antifreeze added). Worn under the flak jacket, it keeps the trunk of the wearer cool, thus greatly reducing the "heat load" and potential for heat stroke or heat fatigue. It was originally meant to be used by pilots in smaller (un-air-conditioned) helicopters or door gunners of larger choppers.
