After the war, Whippets were sent to Ireland during the Anglo-Irish War as part of the British forces there, serving with 17th Battalion, Royal Tank Corps. Seventeen were sent with the Expedition Forces in support of the Whites against Soviet Russia. The Red Army captured twelve, using them until the 1930s, and fitted at least one vehicle with a French 37 mm "Puteaux" gun. The Soviets, incorrectly assuming that the name of the engine was "Taylor" instead of "Tylor" (a mistake many sources still make) called the tank the "Tyeilor". A few (perhaps six) were exported to Japan, where they remained in service until around 1930.
