25x137mm Bushmaster


The 25x137mm Bushmaster is a primarily vehicle utilised auto-cannon cartridge with a wide range of ammunition that has been developed for this munition, providing weapons that utilise it with the capability to defeat the majority of armored vehicles it is likely to encounter, up to and including some light tanks. The ammunition used in the M242 Bushmaster Chain Cannon may also be used in a variety of weapons such as the GAU-12 Equalizer, the French Giat M811, or the Swiss Oerlikon KBA weapon system.

Despite its wide use in vehicles, it is almost never utilised in man portable weapons due to the power, weight and size of the munition, however one such weapon does exist, the Laku Solutions LRAMW-25 (Light Recoil Anti Materiel Weapon-25mm), which is a 39 kilogram anti-materiel rifle designed to give the capability for defeating light vehicles, powered infantry armor, exo-skeletons and mechas to an infantry platoon.
