Direct proof of use
The BM-7 Parus weapon station is directly documented in Ukrainian use during the 2014 Russia-Ukraine War through reporting on a 57th Mechanized Brigade frontline vehicle and official Ukrainian BTR-4E service material. Defense Express reported on 31 August 2024 that a unit of Ukraine's 57th Mechanized Brigade operated a combat vehicle described as a BMP-2 with a BM-7 Parus weapon station, based on an ArmyTV report from the frontline. The same article recorded the identification caveat that some observers treated the chassis as a PRP-3 armored reconnaissance vehicle rebuilt as an infantry fighting vehicle.
Ukraine's Ministry of Defence later described the BTR-4 Bucephalus as being in service with the Security and Defence Forces of Ukraine and specifically identified 20th Operational Brigade "Lubart" BTR-4E vehicles as equipped with the BM-7 Parus weapon station. That official account supports the Parus station's wartime Ukrainian service on BTR-4E vehicles, while the Defense Express/ArmyTV material supports the non-standard tracked-vehicle appearance.

Timeline
The available dated conflict-use record is concentrated in the full-scale phase of the war. On 31 August 2024, Defense Express published its report on the 57th Mechanized Brigade vehicle with the Parus station, including the ArmyTV frontline-report context and the PRP-3 identification caveat.
On 9 April 2026, Ukraine's Ministry of Defence published a BTR-4 Bucephalus overview tied to an Army Media report on the 20th Operational Brigade "Lubart". The overview described the BTR-4E as equipped with BM-7 Parus and noted additional counter-drone protection, placing the weapon station in a continuing Ukrainian service context during the war.

Battlefield role
In the conflict record, BM-7 Parus appears as a remotely controlled direct-fire station for Ukrainian armored vehicles rather than as a standalone weapon. Defense Express described the 57th Brigade vehicle's Parus station as having day, night, and infrared sighting channels and an automatic 30 mm cannon whose most-used rounds were high-explosive fragmentation types. The report presented the vehicle's practical role as infantry fire support, with the commander coordinating from outside the vehicle while the crew operated the vehicle and weapon station.
The BTR-4E context shows the same weapon-station package on a standard Ukrainian armored vehicle family. Ukraine's Ministry of Defence described the BTR-4's BM-7 Parus station as including a 30 mm ZTM-1 automatic cannon, a 30 mm KBA-17 automatic grenade launcher, a 7.62 mm machine gun, and anti-tank guided missile capability. It also noted that the gunner sits inside the hull and that the commander has an independent panoramic sight for target designation.
The strongest public sources therefore support two related but separate claims: Ukrainian BTR-4E vehicles in wartime service carry the BM-7 Parus station, and a 57th Mechanized Brigade unit used a non-standard tracked combat vehicle reported as carrying the same station. The sources do not provide a public fleet count or a comprehensive list of all Parus-equipped vehicles in the war.
