The Morris Commercial C8 FAT (Field Artillery Tractor), commonly known as a Quad, is an artillery tractor used by the British and Commonwealth (including Canadian Army) forces during the Second World War. It was used to tow field artillery pieces, such as the 25-pounder gun-howitzer, and anti-tank guns, such as the 17-pounder. The Ordnance QF 25-pounder, or more simply 25-pounder or 25-pdr, was the major British field gun and howitzer during the Second World War, possessing a 3.45-inch calibre. It was introduced into service just before the war started, combining both high-angle and direct-fire abilities, a relatively high rate of fire, and a reasonably lethal shell in a highly mobile piece. It remained the British Army's primary artillery field piece well into the 1960s, with smaller numbers serving in training units until the 1980s. Initial production was slow, but by 1945, over 12,000 had been manufactured. The 25-pounder was probably the most outstanding field artillery piece used by British and Commonwealth forces in the Second World War, being durable, easy to operate and versatile.
