Medium Soviet tank T-72, whose development has been running since 1967, in some respects followed the type T-64, but has seen much greater expansion. As with the T-64, 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.
