M1117 Guardian

M1117 Guardian. The M1117 Guardian is a 4x4 armored security vehicle developed and manufactured in the United States by Textron Marine & Land Systems. Designed to provide enhanced protection against ambushes, land mines, and improvised explosive devices, it entered service with the United States Army and United States Marine Corps primarily for military police and convoy escort duties. Its distinctive design features a V-hull for blast deflection and a one-man Mk 19/M2-equipped Common Remotely Operated Weapon Station (CROWS).

Development and design

The vehicle's development originated in the late 1980s as a private venture by Cadillac Gage, later part of Textron Marine & Land Systems, to meet a perceived need for a survivable light armored vehicle. The design evolved from the earlier V-150 series, incorporating lessons from Operation Desert Storm and emerging asymmetric threats. Key design features include a fully welded aluminium alloy hull with composite armour and steel appliqué plates, providing protection against 7.62×51mm NATO armor-piercing rounds and overhead artillery bursts. Its independent suspension and central tire inflation system offer improved mobility over rough terrain compared to heavier platforms like the M1126 Infantry Carrier Vehicle. The integration of the Common Remotely Operated Weapon Station allows the crew to engage targets from within the armored capsule, significantly enhancing crew survivability.

Operational history

The M1117 was first deployed in significant numbers during the Iraq War, where it was urgently fielded in 2004 to counter the widespread threat of improvised explosive devices and ambushes against softer-skinned vehicles like the Humvee. It saw extensive use with military police units in Baghdad, Fallujah, and other urban centers, performing route reconnaissance, convoy security, and force protection missions. The vehicle also served in the War in Afghanistan, particularly for protecting Forward Operating Bases and dismounted infantry patrols. Its service highlighted a shift in U.S. military doctrine towards more heavily protected vehicles for counter-insurgency operations, influencing later programs like the Joint Light Tactical Vehicle. Several Guardians were also deployed to support United Nations and NATO missions in regions like Kosovo.

Variants

Operators

The primary operator is the United States Army, with vehicles assigned to Military Police brigades and National Guard units. The United States Marine Corps also fielded a limited number for security and law enforcement tasks. Internationally, the vehicle has been exported to several allied nations, including Iraq (for its Army and Federal Police), Colombia (used by the National Army of Colombia), Lebanon (for the Lebanese Armed Forces), and Ukraine. Ukraine received multiple vehicles as part of security assistance packages following the Russian invasion of Ukraine in 2022, deploying them for rear area security and territorial defense.

Specifications

The M1117 Guardian is a four-wheeled vehicle with a crew of three (commander, gunner, driver) and space for one additional passenger. It is powered by a Cummins 6CTA8.3 turbocharged diesel engine producing 260 horsepower, coupled to an Allison MD3560 six-speed automatic transmission, enabling a top road speed of 100 km/h. Its run-flat tires and independent suspension provide robust cross-country mobility. Standard armament consists of a Mk 19 grenade launcher (40mm) and an M2 Browning machine gun (.50 caliber) mounted on a Common Remotely Operated Weapon Station. Communications equipment typically includes AN/VRC-series radios and AN/PRC manpack systems. The vehicle's composite armour system is designed to meet STANAG 4569 Level III ballistic protection and Level 2a/2b mine protection standards.
