Like all Soviet-legacy tanks, the T-72's design has traded off interior space in return for a very small silhouette and efficient use of armour, to the point of replacing the fourth crewman with a mechanical loader. The basic T-72 design has extremely small periscope viewports, even by the constrained standards of battle tanks and the driver's field of vision is significantly reduced when his hatch is closed. The steering system is a traditional dual-tiller layout instead of the easier-to-use steering wheel or steering yoke common in modern Western tanks. This set-up requires the near-constant use of both hands, which complicates employment of the seven speed manual transmission .
This designator was not only used for the standard T-72M, but also for 75 basic T-72's that were upgraded by RWN in 1986. These tanks (Kampfpanzer) were fitted with rubber side skirts, smoke grenade launchers "Tucha" and the additional 16 mm steel plate on the upper glacis plate. The T-72 was supplied to East Germany by the Soviet Union in the 1970s they outclassed the West German M48 and Leopard 1 and American M60A1 Patton but it was matched when the M1 Abrams and Leopard 2 came out, when Germany reunified in the 1990s the Bundeswehr got the East German T-72 but it didn't stay in service for the German Army for too long some were given to Museums and the rest sold to other countries.
