Ground vehicles

The Corps operates the same HMMWV as does the Army, which is in the process of being replaced by the Joint Light Tactical Vehicle (JLTV). However, for its specific needs, the Corps uses a number of unique vehicles. The LAV-25 is a dedicated wheeled armored personnel carrier, similar to the Army's Stryker vehicle, used to provide strategic mobility. Amphibious capability is provided by the AAV-7A1 Assault Amphibious Vehicle, an armored tracked vehicle that doubles as an armored personnel carrier, due to be replaced by the Amphibious Combat Vehicle, a faster vehicle with superior armor and weaponry. The threat of land mines and improvised explosive devices in Iraq and Afghanistan has seen the Corps begin purchasing heavy armored vehicles that can better withstand the effects of these weapons as part of the Mine Resistant Ambush Protected vehicle program.

The Marines operate the M777 155 mm howitzer, including the High Mobility Artillery Rocket System (HIMARS), a truck-mounted rocket artillery system. Both are capable of firing guided munitions. In 2020, the Marine Corps retired its M1A1 Abrams tanks and eliminated all of its tank units. General David Berger explained the decision describing the long-serving Marine weapons system as "operationally unsuitable for our highest-priority challenges." The move leaves the Army as the sole operator of American tanks.
