T-72B Series The T-72B and its variants was the main tank model used in the Soviet Central Group of Forces, The subsequent CFE talks revealed the following versions in use with the Russian and CIS armies. T-72B - essentially a further development of the T-72A model with a number of modifications that includes a more powerful engine, improved armour protection and an upgraded fire-control system to fire the AT-11 Sniper semi-laser guided ATGW. Radiation liners are fitted to the turret top, sides and rear. T-72BK - command version of T-72B with additional radio, second antenna and land navigation system. T-72B1 - identical to the T-72B but has no ATGW capability and is fitted with a

The size of the modified turret has meant that the
bottom edge of the front turret lobes has had to be cut away in order to allow the turret to rotate freely. T-72S - See separate T-72S entry. T-72S1 - See separate T-72S entry. The T-72B series carry the fully stabilised 125 mm gun with the same light alloy thermal sleeve, bore evacuator and 22-round carousel-type autoloader of the other T-72 variants but carries 45 main 125 mm rounds (including the 6 AT-11 ATGW) instead of the earlier variants smaller basic load of conventional rounds. There is, however, a commensurate drop in the number of basic load rounds for the 7.62 mm PKT coaxial and 12,7 mm NVST anti-aircraft machine guns. The latter, unlike on the
