M10 Booker

The M10 Booker is an American assault gun that General Dynamics Land Systems built for the United States Army. It was developed from the company's Griffin II armoured fighting vehicle, itself derived from the Austrian-Spanish ASCOD 2 platform, and won the Army's Mobile Protected Firepower competition in June 2022 with an initial contract for up to 96 vehicles. It is a fully tracked vehicle with a four-person crew, a 105 mm M35 gun using the same fire control system as the M1A2 Abrams, modular armour and an automatic fire suppression system. The Army named it in June 2023 for two soldiers named Booker and took delivery of the first production vehicle in February 2024. It weighs about 38 to 42 tons, more than planned, and the Army cancelled the programme in 2025 after taking at least 26 vehicles.
