1× 40 mm Mk 19 grenade launcher,[5] 1x Mk 47 Striker 1× .50 in (12.7 mm) M2 Browning heavy machine gun,[6] or 1× BGM-71 TOW anti-tank guided missile launcher[7][8][9] The Oshkosh M-ATV is a mine-resistant ambush protected (MRAP) vehicle developed by the Oshkosh Corporation for the MRAP All Terrain Vehicle (M-ATV) program.

Intended to replace M1114 HMMWVs (Humvee), it is designed to provide the same levels of protection as the larger and heavier previous MRAPs, but with improved mobility.

[5] In the summer of 2008, the U.S. Department of Defense (DoD) began to examine the possibility of developing and procuring a lighter-weight, all-terrain capable MRAP variant to address the poor roads and difficult terrain of Afghanistan.

Source selection activity considered responses from more than 20 companies to a Request for Information (RFI)/market survey dated 21 August 2008 and in mid-November 2008 the U.S. government issued a pre-solicitation for an M-ATV.

[12] In March 2009, it became known that two each of six different vehicle types (from five manufacturers) had been delivered to the U.S. Army for two months of evaluation, at the conclusion of which up to five ID/IQ (Indefinite Delivery/Indefinite Quantity) contracts would be awarded.

[23] In total 8,722 M-ATVs were delivered to the U.S. Army, U.S. Marine Corps, U.S. Air Force, and U.S. Special Operations Command (SOCOM).

[24] Work is currently underway at Oshkosh's Wisconsin facility and the Red River Army Depot to reset the around 7,000 M-ATVs retained to a common build standard.

The goal is to use the M-ATV as an unmanned platform for route clearance and counter improvised explosive device (IED) missions by engineers.

The M-ATV EXM's customizable internal configuration also enables equipment to be accessed quickly by a centrally positioned medic.

[29] The M-ATV proved to be more survivable than the Humvee and was lighter than other MRAP versions, but to further enhance survivability and mobility for troops, the U.S. military undertook the Joint Light Tactical Vehicle (JLTV) program to obtain a vehicle combining light weight, mobility, and protection.

In August 2015, Oshkosh was awarded the contract for their Light Combat Tactical All-Terrain Vehicle (L-ATV), which took design lessons from fielding the M-ATV and incorporated them into a truck at two-thirds the weight and with faster off-road speeds.

For survivability, and in addition to the V-shaped hull which is optimized for IED protection, other aids include the ability to take a 7.62 mm round to the engine oil/coolant/hydraulic system and continue to drive for at least one kilometer.

Other M-ATV features include a HVAC system and power outlets for charging portable electronic devices.

These are to provide greater off-road mobility and crew protection for regional security and peace-keeping operations; users include the elite Presidential Guard.

[4] On 7 April 2014, the U.S. government donated 162 M-ATVs to the Croatian Army for use in small-scale combat operations in urban and restricted environments.

[40] In January 2015, it was reported that the U.S. was to donate 308 Mine Resistant Ambush Protected (MRAP) vehicles to Uzbekistan under the Excess Defense Articles program.

Delivery of the MRAP vehicles was carried out within the framework of the Excess Defense Articles program, the standard way that the U.S. military gives surplus equipment to allies.
