By the outbreak of the First World War, the British Army had adopted the Vickers Machine-gun. Fitted with interrupter gear, the Vickers was also standard armament on all British and French aircraft after 1916. During the war the British also used the Lewis Gun. Easier to produce and far lighter than the Vickers, it was used by soldiers on the Western Front and on armoured cars and aircraft.
In the Second World War the British Army used the extremely reliable Vickers 303. It was a recoil-operated machine gun, water cooled and belt fed. It weighed 40lb without its tripod and fired the standard .303 British cartridge at about 450rpm.
