The M10 Booker is an American assault gun produced by General Dynamics Land Systems (GDLS) for the United States Army. The M10 was developed from the GDLS Griffin II armored fighting vehicle as the winner of its Mobile Protected Firepower (MPF) program in June 2022. The initial contract was for 96 low rate initial production (LRIP) vehicles, the first of which were delivered in February 2024.
The Army canceled the Booker in 2025, partly due to its excessive weight, but according to tank historian Nicholas Moran, due to shifting priorities in the US military budget, where the M10 did not meet the required need for continued funding. The Army had taken delivery of at least 26 vehicles before the program's cancelation. These have an uncertain future and may be transferred to armored units, sold abroad, or placed in storage.
