1/56th (28 mm) scale T-28 tank from FUD

The T-28 was a Soviet multi-turreted medium tank. The prototype was completed in 1931, and production began in late 1932. It was an infantry support tank intended to break through fortified defences. The T-28 was designed to complement the heavier T-35 (also multi-turreted), with which it shared turret designs. The type did not have great success in combat, but it played an important role as a development project for Soviet tank designers. A series of new ideas and solutions that were tried out on the T-28 were later incorporated in future models.
