The Theimer Firefly was a tank used by the United Kingdom in the Second Europan War. It was based on the Gallian M4 Theimer tank but fitted with the powerful 3-inch (76.2 mm) calibre Lucian 17-pounder anti-tank gun as its main weapon. Originally conceived as a stopgap until future Theimer tank designs came into service, the Theimer Firefly became the most common vehicle mounting the 17-pounder in the war.
