"The T-72M2 Wilk (Polish for “Wolf”) is one of the results of the Polish attempts from the late 1980s to upgrade its aging fleet of T-72M1 tanks in order to provide an effective counterpart to the western Leopard 2 and Abrams MBTs. The Polish development program resulted in several prototypes built between 1987 and 1990, featuring a more powerful engine, better Fire Control System and a Polish ERAWA explosive reactive armor kit. The Wilk program was concluded in 1990 but the lessons learned from it were used in the construction of the Polish PT-91 Main Battle Tank.
In Armored Warfare, the T-72M2 Wilk is a Tier 6 Main Battle Tank. It’s based on the T-72M1, which is an export version of the T-72A. That, along with improved mobility and the ERAWA ERA kit, puts it one tier above its predecessor. Performance-wise, it’s comparable to the T-72B Main Battle Tank with its experimental Polish DRAWA FCS and the improved autoloader increasing its performance."
