English: Pictured: Personnel on the Combined Arms Manoeuvre school (CAMS) Machine Gun Course in Warminster firing the General Purpose Machine Gun (GPMG). The L7A2 General Purpose Machine Gun (GPMG) is a 7.62mm x 51mm belt-fed general purpose machine gun which can be used as a light weapon and in a sustained fire (SF) role. In the SF role, mounted on a tripod and fitted with the C2 optical sight, it is fired by a two-man team who are grouped in a specialist Machine Gun Platoon to provide battalion-level fire support. In SF mode, the GPMG, with a two-man crew, lays down 750 rounds-per-minute at ranges up to 1800 metres. The GPMG can be carried by foot soldiers and employed as a light machine gun (LMG). A fold-out bipod is used to support the GPMG in the LMG role. Versions of the GPMG are mounted on most Army vehicles and some helicopters. The Combined Arms Manoeuvre School (CAMS) provides combat and Combined Arms Manoeuvre individual training, from initial training to sub-unit, Battle Group commanders and, in time, formation staff (Brigade and Division staff). Comprising of units formerly known as the Specialist Weapons School and the Reconnaissance and Armoured Tactics Division, the Combined Arms Manoeuvre School (CAMS) is based at Warminster and delivers agile and adaptable specialist weapons training to Officers and Soldiers of the Field Army.
