Mine Resistant Ambush Protected M1117 Guardian
Definition/Scope: The M1117 Guardian Armored Security Vehicle, or ASV, is an all-wheel drive armored vehicle manufactured by Cadillac Gage of Textron for use by the United States Army Military Police Corps. Its armament consists of an Mk 19 grenade launcher and M2 Browning Machine Gun, mounted in a turret similar to that used on the US Marine Corps’ Amphibious Assault Vehicle; and a M249 Squad Automatic Weapon mounted outside the gunner’s hatch. It is a more heavily protected and heavily armed alternative to the armored HMMWV that was not originally designed to be a protected fighting vehicle. At about 15 tons, the M1117 is lighter than the 20 ton Stryker ICV or 25 ton M2 Bradley armored vehicle. It is only 2.4 meters wide, compared to 3.6 meters for a Bradley. Its road speed of 100 kilometers per hour is higher than the 70 kilometers per hour of an M2 Bradley. Buttoned up, the crew has 360-degree visibility. In size and capability, it fits between the Humvee and the $2.8 million Stryker. The crew compartment is fully air-conditioned. The Guardian’s armor is designed to defeat .50 caliber armor piercing ammunition, 12-pound anti-tank mines, and 155 mm artillery from 15 m above. Unlike some other designs that resemble conventional trucks, the armor is angled presenting no vertical surfaces, deflecting many Rocket Propelled Grenade hits. If an RPG does hit the vehicle directly, it can still function, although crew deaths and injuries will vary depending on where the RPG hits. Angled armor is more resistant to attack than vertical armor due to the V-shape hulls deflecting explosive forces (due to their shape), as opposed to a single-plane hull which takes the entire force impact.
