M1150 Assault Breacher Vehicle

These tracked combat vehicles were specifically designed to clear pathways for troops and other vehicles through minefields and along roadside bombs and improvised explosive devices. The 72-ton, 40-foot-long (12 m) vehicles are based on the M1 Abrams with a 1,500 horsepower engine, but fitted with only a .50 cal machine gun and a front-mounted 15-foot-wide (4.6 m) plow, supported by metallic skis that glide on the dirt and armed with nearly 7,000 pounds (3,200 kg) of explosives.

They are equipped with Linear Demolition Charge System (LDCS): rockets carrying C-4 explosives up to 100–150 yards forward, detonating hidden explosives at a safe distance, so that troops and vehicles can pass through safely.[1]

In the 1990s, the U.S. Army decided it could not afford to continue developing complicated, maintenance-heavy vehicles for this purpose. The Grizzly program was cancelled in 2001, and the prototype developed never made it to the production lines. The Marine Corps however persisted and funded its own development and testing. The main body of the final model of the ABV is built on the General Dynamics chassis that is used for the M1A1 Abrams main battle tank. Pearson Engineering of the UK provided the specially designed plow and the other mine-clearing accessories.[2][3][4]

In the morning of December 3, 2009, for the first time breachers were used in combat, when Marines pushed into the Taliban stronghold Nawzad during Operation Cobra's Anger in Helmand province, on their way to another Taliban stronghold Marjah, 380 miles (610 kilometers) southwest of Kabul, that was to be assaulted in February 2010.[5][6][7][8][9]

On February 11, 2010, two breachers fired explosive line charges in the desert outside Sistani to test Taliban defenses on the eve of Operation Moshtarak when closing off the enemy's escape route.[10][11][12][13]

On February 13, 2010, on the first day of the operation, breachers of the US Marines 2nd Combat Engineer Battalion succeeded in digging and blasting "safety lanes" through the numerous minefields laid by the Taliban around Marjah.[14][15]

According to a report in December 2009, there were then five ABVs in Afghanistan, and the U.S. Marines were said to have plans to field a total of 52 by 2012, of which about 34 have already had been produced. The U.S. Army was said to have ordered 187.[16]

By August 2013, six ABVs were brought to the Korean Peninsula to be used by the 2nd Infantry Division (2ID) to provide the capability for deliberate and in-stride breaching of mine fields and complex obstacles. The ABVs would allow the 2ID to clear the heavily mined Korean Demilitarized Zone, believed to contain tens of thousands to millions of mines. A previous deployment of MRAP mine-resistant vehicles to Korea caused North Korea to accuse their presence as vehicles that would cross the DMZ for an attack of the country; the MRAPs were later withdrawn due to their unsuitability for the terrain. North Korea has not publicly responded to the ABVs’ arrival on the peninsula.[17][18]

In 2019, the USMC's Force Design 2030 decision to divest of its Armor component included the ABV. This divestment transferred the majority their ABV inventory to the Army. This action resulted in the US Army being the sole branch of the US Military with under-armor mechanical breach capability.[19] As of 2023, the USMC had divested the ABV.[20]

In April 2021 the US Department of State approved the sale of 29 M1150s to Australia, where they will be operated by the Australian Army.[21]
