However, the visual revealed at Enforce Tac 2026 seems to maintain the Boxer Overwatch role of providing close anti-armour support within heavy combat formations while refining packaging and integration. The first Boxer-Brimstone SL concept emerged in 2021 within the framework of the British Army’s Battle Group Organic Anti-Armour (BGOAA) programme, which aimed to replace legacy anti-tank systems, including Swingfire, Javelin, NLAW, and ASM, with a new system expected to enter service during the 2030s. In that initial configuration, the Brimstone launcher consisted of a large rectangular pack mounted externally on the left-rear side of the Boxer hull. The launcher contained 16 missiles arranged in a 2x8 grid within a single box enclosure and sat relatively low, protruding laterally beyond the side profile of the vehicle.
No visible elevation or traverse mechanism was integrated into the mount on this first variant, indicating a fixed or minimally adjustable firing arrangement, according to the render released at that time.
