Notes: This is a Polish modification of the T-72M1. The PT-91 typically mounts second-generation ERA on the HF, TF, and TS. A laser warning system notifies the commander when a laser rangefinder or designator is targeting his tank. There are 12 smoke grenade launchers on each side of the turret. The fire control is computerized, with a laser rangefinder. The engine is 11% more powerful. Finally, the PT-91 is normally painted with radar-absorbent paint. The first prototype appeared in 1992, and a small amount have been built for the Polish Army.
