The BM-7 Parus is a Ukrainian remotely controlled weapon station for light armoured vehicles, combining a 30 mm ZTM-1 cannon, 7.62 mm machine gun, 30 mm grenade launcher, and Barrier anti-tank missiles in a self-contained turret. It is documented on the BTR-4 family and in Ukraine-war reporting on a non-standard BMP-2 or PRP-3-based frontline vehicle, giving crews protected direct-fire support from inside the hull.
Defense Express tied an ArmyTV frontline report from Ukraine's 57th Mechanized Brigade to a non-standard infantry fighting vehicle described as a BMP-2 with a BM-7 Parus weapon station, while noting uncertainty over whether the chassis was actually a PRP-3 conversion.
Role detailsPublic sources document BM-7 Parus both as the standard BTR-4 family weapon station and as a retrofit on at least one non-standard Ukrainian frontline vehicle.
