The Medium A "Whippet" was developed from the Tritton "Chaser" Whippets wewre assigned to 3rd and 6th Bns (48 each), both in 3rd brigade.

German troops captured at least one Medium A, but records do not show that any Medium A's were used by Germany in combat. This model is a "what-if" - if Germany had used them, they might have been painted as this model. It might have been employed as the other German tanks, in units of 5 vehicles.

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.
