In 2015, the US Army started the Mobile, Protected Firepower (MPF) programme with the aim of creating a lightweight combat vehicle based on commercial off-the-shelf options. This programme was started to fulfil a capability gap recognised within the Infantry Brigade Combat Teams (IBCT), in that there was no direct-fire support vehicle available for the infantry beyond HMMWVs with TOW missiles, a capability gap that had been present since the retirement of the M551 Sheridan and the cancellation of the M8 Armored Gun System.

Among the contenders for the MPF programme were BAE Systems with a modified M8 AGS and General Dynamics Land Systems with a modified Griffin II based on the ASCOD 2 chassis. Following an evaluation period, the GDLS Griffin II was selected as the MPF winner in June 2022 and christened in June 2023 as the M10 Booker, named after two decorated US Army soldiers (Private Robert D. Booker and Staff Sergeant Steven A. Booker). It was initially intended to procure 96 M10 Bookers, with each IBCT fielding 14 M10 Bookers, and future plans listed the procurement of a total of 504 Bookers to field them in all light divisions. However, in April 2025, due to the new "Army Transformation and Acquisition Reform" initiative, which aimed to end procurement of systems deemed obsolete, ineffective, or redundant, the M10 Booker was cancelled after just 26 vehicles were produced.

Introduced in Update 2.53 “Line of Contact”, the M10 Booker gets its chance to shine in combat. As a “light tank”, the M10 Booker benefits from reconnaissance and sensor capability advantages, with thermal optics and even an IRST tracker for low-flying aircraft, giving the player a vehicle with significant potential for spotting and targeting enemies as a light tank, while also having a 105 mm cannon to be able to respond kinetically to opportunities.
