The M1117 Guardian, also denoted Armored Security Vehicle (ASV), 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.[1] The first prototypes appeared in February 1997 and serial production of the M1117 commenced between 1999 and early 2000.[1]

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.[2][3] Its armament consists of an 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.

The vehicle was utilized by American military police and convoy security units in Iraq and Afghanistan. It is a more heavily protected and heavily armed alternative to the armored M1114 HMMWV aka "Humvee", which was not originally designed to be a protected fighting vehicle.

History

U.S. Army National Guard M1117 Armored Security Vehicles at Fort Stewart, Georgia in June 2010.

The vehicle (originally the ASV-150) is a purpose-built 21st-century version of Cadillac Gage's V-100 Commando family of Armored fighting vehicles which was used by the U.S. Army Military Police during the Vietnam War;[4] whose duties often consisted of providing armed escort for wheeled convoys. The USAF in South Vietnam utilized an open hatched (turret-less) Commando for base security missions.[5] The ASV 150 was a much improved version of the earlier Cadillac Gage vehicle, with improved armor protection and better maneuverability due to the use of Timoney's independent suspension system.

In the 1980s, U.S. military doctrine emphasized two distinct types of equipment. Tanks and infantry fighting vehicles were for frontline combat, and unarmored utility vehicles for transport behind the lines.[6] In 1993, the military had to fight through Mogadishu in unarmored Humvees, leading to the development of up-armored models. Many generals doubted the benefits, but the Military Police Corps, tasked with patrolling the "safe" rear area behind the battle line, insisted that the Army fund a slow but steady production of the bullet resistant M1114 Humvee.

A M1117 at Fort Irwin National Training Center

In 1999, the United States Army began buying a limited number of M1117s for the Military Police Corps. They were field tested by MP units in Kosovo, mostly by members of the 709th MP Battalion.[7] The program was canceled in 2002 because of budget priorities. The United States Army believed that existing vehicles could be used without an "unacceptable level of risk."[7] (At $800,000 each in 2011, the M1117 was significantly more expensive than the $140,000 price for an M1114 and $220,000 for an armoured M1114.)[8]

When the Iraq War began in 2003, there were 49 ASVs in service, with almost all of them being assigned to MP units. The first MP unit to officially use them in a combat zone was the 527th MP Company and other elements of the 720th Military Police Battalion. However, the onset of events in Iraq gave new life to the ASV program as HMMWVs proved vulnerable to attacks and a large source of casualties. Up-armored HMMWVs were not designed to be armored cars like the M1117, which are designed to withstand hits from small arms, mines and rockets in front-line combat units. Soldiers who used the M1117s, and some members of Congress visiting Iraq, favored them over other mine protected vehicles.


A variant was to be evaluated by the United States Marine Corps as part of the Mine Resistant Ambush Protected (MRAP) vehicle program. In May 2007, after its vehicle submission failed ballistics testing at Aberdeen Proving Ground, Textron received word that it would not receive further orders as part of the MRAP program.[9] However, in early 2008, Textron was awarded a contract worth $228 million to build 329 ASVs, to be delivered with the latest fragmentation protection kits. The total number of ASVs produced and remaining to be delivered to the U.S. Army at the time was 2,058 vehicles.[10]

In April 2019, the M1117 was added to the Master Divestiture List. In time, they will be replaced with the M-ATV.[11]

Design

The turret has a .50 caliber M2HB machine gun (left) and Mk 19 grenade launcher (right)

At about 15 tons, the M1117 is lighter than the 20 ton Stryker ICV or 25 ton M2 Bradley armored vehicle. It can reach a speed of 20 miles per hour in 7 seconds.[12] It is only 7 feet 9 1⁄2 inches (2.375 meters) wide, compared to 11 feet 9 1⁄2 inches (3.594 meters) for a Bradley. Buttoned up, the crew has 360° visibility. In size and capability, it fits between the Humvee and the $5 million Stryker. The crew compartment is fully air-conditioned.

Survivability

The ASV uses an advanced modular expandable armor package from IBD Deisenroth Engineering, consisting of ceramic composite applique on the exterior and spall liner on the interior. The Guardian's armor is designed to defeat small arms fire, mines and Improvised Explosive Devices (IEDs). The armor is angled presenting no vertical surfaces, deflecting many rocket-propelled grenade (RPG) hits. If an RPG does hit the vehicle directly, it can still function, although crew survivability varies depending on the location at which the RPG hits.[13] Angled armor is more resistant to attack than vertical armor due to the shape of the V-shape hulls deflecting explosive forces, as opposed to a single-plane hull which takes the entire force impact.

ASVs in Iraq and Afghanistan have withstood several IED attacks, some vehicles multiple times. One ASV returned 28 miles (45 km) after an IED destroyed all four tires.[citation needed] As for chemical and biological attacks, the ASV's gas particulate air filtration system was designed to provide additional protection, but is currently not in service due to lack of crew masks for the system. The ASV has experienced several rollover incidents. Soldiers have a higher survivability rate when rolling over, as the turret is fully enclosed protecting the gunner from ejection. However, there have been at least two incidents of rollovers that resulted in the deaths of two soldiers when the turret broke away from the vehicle.[14][15] Since the incidents, Textron has started adding 15 additional bolts to the vehicle turret.

Mobility

A M1117 navigates through an obstacle at a rough terrain driving course

The typical mission profile of an ASV involves 50% travel primary roads, 30% travel on secondary roads, and 20% cross-country travel. It uses a model MD3560 Allison Transmission. Front and rear independent suspension provides smooth highway speeds of up to 70 mph (110 km/h), while it is capable of fording 5-foot (1.5 m) depths of water, climbing gradients of 60%, negotiating 30% side slope, and overcoming obstacles of five feet. Its turning radius is 27.5-foot (8.4 m), and it has 18-inch (46 cm) ground clearance.


The M1117 can ford water up to 5 feet deep.[16]

Variants

The following variants are known to be in production/service:[17]

  • Command & Control
  • Recovery Vehicle (Each ASV can flat tow another ASV or HMMWV)
  • Reconnaissance Surveillance & Target Acquisition (RSTA)
  • Ambulance
  • Infantry Carrier Vehicle (ICV, alternate name for an Armored Personnel Carrier (APC)) – 24 in longer than ASV, armed with cupola mounting for a machine gun or grenade launcher instead of a turret, carries 3 crew and 8 troops.[18]
  • M1200 Armored Knight FiST-V

Direct fire support variant

With the adoption of the M1117 as the Mobile Strike Force Vehicle (MSFV) by the Afghan National Army, demand increased for much larger caliber weapons systems mounted on the same chassis which would provide it with an organic anti-tank and fire support capability.[19] On 22 October 2013, a new fire support variant of the M1117 was unveiled by Textron at the annual Association of the United States Army (AUSA) exhibition.[19] This model, described as the Commando Select 90mm Direct Fire Vehicle, was designed with an exceptionally large turret ring and carried a Cockerill Mk III 90mm low-pressure cannon.[19]

It provided the M1117 with an extremely potent form of firepower for its size and weight class, firing canister, high explosive, high explosive squash head, and high explosive anti-tank shells, as well as an armour-piercing discarding sabot round capable of destroying older main battle tanks.[20] One advantage of the low-pressure cannon was that, in spite of its relatively large caliber, it could be mounted on a vehicle weighing only 18 metric tonnes, or about 40,000 pounds, combat loaded.[20] The new armament was also fitted with a single-baffle muzzle brake and concentric hydro-spring recoil mechanism as standard to reduce the pressure exerted on the relatively light chassis.[1]

According to Textron, it invested in the 90mm Direct Fire Vehicle as a direct response to the Afghan requirement for a more heavily armed MSFV.[21] Afghanistan immediately ordered 50 and offered to purchase the vehicle through the Foreign Military Sales (FMS) program, with grants from the US government.[22] However, since the 90mm cannon and most of the turret components were made in Belgium, US military officials blocked the sale until they could qualify and approve that particular combination for export through FMS.[22]

In 2014, the procurement process was suspended when the US canceled its funding for the sale of almost 300 MSFVs, including the 50 Direct Fire Vehicles, to the Afghan National Army, citing budgetary constraints.[23] The US military had not yet finished its testing of the Belgian weapons system at the time, so none were ever delivered.[22] As Kabul's requirement for a fire support variant of the MSFV remained unfulfilled, Textron agreed to revisit the potential sale with Afghan officials in 2017.[22]

Around the same time, Iraq requested an undisclosed number of 90mm Direct Fire Vehicles from Textron for its ongoing campaign against the Islamic State of Iraq and the Levant. The sale was pending review by the US government in February 2017.[24]

Textron Tactical Armoured Patrol Vehicle

The Textron Tactical Armoured Patrol Vehicle (TAPV) are used by the Canadian Army and is a heavy armoured upgrade of the M1117. 500 in service[25]

Foreign variants

Bulgaria uses a variant of the M1117 APC fitted with a NSVT heavy machine gun instead of the M2. Not all vehicles have been converted this way.

The Iraqi Armored Personnel Carrier ASV variant is configured for transport. Iraq has also modified some of its ASVs' turrets to accommodate an anti-aircraft capability.
