Medium Soviet tank T72, whose development has been running since 1967, in some respects followed the type T64, but has seen much greater expansion. As with the T64, his crew consisted of only three men — the commander, the gunner, and the driver — and the charging was automated. The first units got to the CSLA tank units in 1978. Three years later, an instructional film was created in the Army Film Studio. which introduced the new technology to the soldiers.
