Under the supervision of S.A. Ginsburg, the team at the testing department for the mechanical design at the Leningrad Machine Factory promptly bought together the required elements in a new multi-turreted tank design. By 1932, test models were ready for field trials; designated as the T-28 it was amongst some of the world’s first medium tank designs.

When the T-28 tank went into service in 1933 it was a cutting edge design for its time and remained a formidable sight on the battlefield during the battles of 1939. Once it was armed with the long 76mm L-10 gun on the introduction of the 1938 model, it could easily knock out most enemy tanks.
