M1117 armored security vehicle

The M1117 armored security vehicle (ASV; nicknamed Guardian) is an internal security vehicle based on the V-100 and V-150 Commando series of armored cars. It was developed in the late 1990s for service with the United States' Military Police Corps. The first prototypes appeared in February 1997 and serial production of the M1117 commenced between 1999 and early 2000. The M1117 was one of the first U.S. military vehicles to be built on a specialized mine-resistant hull, and after 2001 was adopted in increasing numbers as a direct response to the threat posed by improvised explosive devices to US forces in Iraq and Afghanistan. Its armament consists of a Mk 19 grenade launcher and M2HB Browning machine gun, mounted in a turret similar to that used on the United States Marine Corps' Amphibious Assault Vehicle, and a M240H Medium Machine Gun mounted outside the gunner's hatch.
