Army Operational Shooting Competition

The Army Operational Shooting Competition (AOSC), is the British Army's premier shooting competition. Part of the Central Skill at Arms Meeting (CENTSAAM), it is based at the headquarters of the National Rifle Association (NRA) at Bisley Camp, in Brookwood, Surrey. It also uses Ministry of Defence (MOD) ranges in the vicinity, such as Ash and Pirbright.

History
Competition shooting in the British Army started in 1874 with 'non-central' matches on unit ranges. The 'Army VIII' was formed in the same year, its purpose was to select a team for Inter-Service matches organized by the National Rifle Association (NRA). The Army Rifle Association (ARA) which was founded in 1893, became the governing body of service shooting. It was formed to encourage interest in service shooting to "promote interest in small arms shooting for service purposes by means of collective competitions, matches being framed to induce practice in methods which le[a]d to increased efficiency on the battlefield". By the 1970s, all three services had established their own competitions and associations, the army's going under the name of 'Regular Army Skill at Arms Meeting' or RASAM, (also known as 'RASAAM'). As part of constant up-dating, the event's name was changed to the 'Army Operational Shooting Competition' in 2009.

Figure targets were first used in 1908. The electric target range (ETR) came on stream in 1967. A moving target match was introduced in 1974 with two infantry night shooting matches being competed-for initially in 1982. Firing in respirators and a 'march and shoot' competition was introduced in 1986. Casualty recovery and the carrying of 15 kilogrammes of personal equipment was brought in in 2009.
