The BT tank series were a series of East Europan light tanks produced from 1930 to 1943. They were lightly armoured, but were well-armed and reasonably fast. An indigenous Gallian tank design, it was sold by Theimer to the East Europan Government due to loss of funding by the Gallian government. Despite it, Theimer's suspension would be utilized by the Lucis Army for its cruiser tank line.
Theimer would go on to design another tank for the Gallian Army, which would later be the M3 Rein tank, and M4 Theimer tank. The Imperials would use the tank until 1931, when it was replaced by the indigenous and far superior Panzer II tank. It was later handed to states such as the Second Estharian Republic, who received more than 5,000 models to boost up its armaments during the Estharian Civil War. The Empire of Quenmin also took interest and bought more than 2,000 models, but mostly BT-2s and BT-5s since the Estharian Republic had already bought most of its stocks.
