The T-72B successfully addressed the immediate problems facing the T-72A. The protection now matched or exceeded the new NATO MBTs that were capable of dispatching the previous model and the fire control upgrades provided a welcome increase in offensive capabilities. This was achieved without sacrificing ease of production and the T-72B was widely produced and exported like prior models. No improvements were made to its mobility, which was now exceeded by the Abrams and Leopard 2, and the fire control system was still inferior to Western tanks. Still, it provided a solid foundation for modernizations like the T-72B3 and will likely stay in service for the next few decades. The famous T-90 had its beginnings as an upgraded "T-72BU" as well.

The T-72B did not see any combat with the Soviet Union. The succeeding Russian Federation has used the T-72B in Chechenya, Georgia, and elsewhere. Other customers and current users of the T-72B include Armenia, Azerbaijan, Belarus, Laos, Morocco, and Syria.
