In about 1962, at the end of National Service, British infantry battalions had reorganised into three rifle companies, a support company and an HQ company with logistic responsibilities. Battalion HQ included an intelligence section. Each rifle company was composed of 3 platoons of 32 men each, equipped with light machine guns and self-loading rifles. The support company had a mortar platoon with six medium mortars (3-inch mortar until replaced by 81-mm mortar around the end of 1965) organised into three sections, enabling a section to be attached to a rifle company if required. Similarly organised was an anti-tank platoon; there was also an assault pioneer platoon. The machine gun platoon was abolished, but the impending delivery of the 7.62 mm GPMG, with sustained fire kits held by each company, was to provide a medium machine gun capability. In the meantime, the Vickers machine gun remained available. The innovation in the new organisation was the formation of the battalion reconnaissance platoon, in many battalions a platoon of "chosen men". In Borneo, mortars were usually distributed to rifle companies, and some battalions operated the rest of their support company as another rifle company.
