Improvements in firepower are achieved by adding one of two new fighting modules (turrets), both of which are armed with one 30 mm ZTM1 or 2A72 autocannon, one 7.62 mm KT or PKT coaxial machine gun, one 9K113 Konkurs (NATO: AT-5 Spandrel) ATGM and one 30 mm AGS-17 automatic grenade launcher. Both main guns are stabilized in the vertical axis (the second variant has a two axis stabilization) and have electro-mechanical aiming drives. Both have a maximum effective range of 4,000 m and can be elevated or depressed between −10° and +60° or −4° and +60°. The vehicle carries 150 rounds (the second variant carries 350 rounds).
