The Medium A "Whippet" was developed from the Tritton "Chaser" in 1917, and first saw battle in 1918. The Whippets were assigned to 3rd and 6th Bns (48 each), both in 3rd brigade. After the war Whippets were sent to Ireland during the Anglo-Irish War as part of the British forces there. "Gofasta" was one of these tanks. Seventeen Medium A's were sent to Russia to bolster the White Army in the Revolution. The Red Army captured twelve of these and used them into the Thirties, fitting at least one vehicle with a French 37 mm Puteaux gun. The Russians named them "Taylor", a misinterpretation of the maker of the tank's engine, Tyler. A few were exported to Japan. A single vehicle was sent to South-Africa to put down labour unrest, and remains at the Armour College in Pretoria. Others may be seen at the Bovington Tank Museum, Aberdeen (Maryland), CFB Borden and The Museum of the Army in Brussels.
