Bren light machine gun
SOE also adhered to the principle that resistance fighters would be handicapped rather than helped by heavy equipment such as mortars or anti-tank guns. These were awkward to transport, almost impossible to conceal and required skilled and highly trained operators. Later in the war however, when resistance groups staged open rebellions against enemy occupation, some heavy weapons were dispatched, for example to the Maquis du Vercors. Weapons such as the British Army's standard Bren light machine gun were also supplied in such cases.
