The turret mount is equipped with the 1PZ-9 day type sight, TPN3-42 night sight, OU-5M searchlight, and 902V smoke grenade discharging system. The vehicle's ammunition load consists of 300 rounds for the main gun (in two 150-round belts) and a 2,000-round machine gun belt. The gunner can select the type of cannon round needed (thanks to the twin-belt cannon feeding scheme) and adjust the rate of fire depending on target type.
Being 2.1 to 2.4 times more efficient in fighting ground targets than APC-mounted 14.5-mm machine gun, the BPPU-1 also halves vehicle losses to helicopter attacks.
The manually-aimed armament is equipped with braking devices. The main gun is cocked electromechanically. The fire control lever has three positions: for single-shot, low, and high rate of fire. The standard APC firepower is complemented by service firearms, a portable grenade launcher, and a portable surface-to-air missile system of the Strela or Igla type MANPADS.
