49th Radio-Technical Brigade
Identification
Military unit 39872 is the Belarusian 49th Radio-Technical (Radio Engineering) Brigade of the Air Force and Air Defence Forces. Belarusian state reporting in November 2025 publicly congratulated the brigade on its 90th anniversary, while the brigade’s official Telegram channel identifies it as an active formation; historical records show the same unit number belonged to the 49th Radio-Technical Regiment that Belarus inherited in 1992.

The two Minsk-area placemarks are consistent with brigade facilities in the greater Machulishchy/Minsk area. Open reporting places v/ch 39872 in Machulishchy, including a 2024 event notice and a 2025 tender for repair of the unit’s headquarters building; however, an ICDS force-structure map labels the brigade at Valerianovo. The open-source picture therefore supports identification of this record as the brigade HQ/primary garrison, but the exact locality label is not fully consistent across sources.

Mission
This formation is part of Belarus’s radio-technical troops, i.e., the radar and air-surveillance arm supporting national air defence. ICDS describes the 8th and 49th Radio-Technical Brigades as operating Belarus’s early-warning and battle-management radar network, and Belarusian official messaging says the brigade stands combat duty around the clock protecting the country’s air borders. A Belarusian MoD press release in January 2014 also stated that a Vostok-D radar entered combat duty in one of the brigade’s subdivisions.

Subordinate battalion
Placemark 2 aligns very closely with the published late-Soviet coordinates for the 2289th independent Radio-Technical Battalion, then subordinate to the 49th Regiment under military unit 39872. More recent independent reporting links the battalion’s 1st radio-technical center in Postavy to the same 49th Brigade. This supports treating the Polotsk-area placemark as a long-standing subordinate battalion location, but current open sources do not fully confirm the battalion’s present HQ at that exact coordinate.

Recent posture
Recent non-official monitoring indicates continued field activity and mobility. Belarusian Hajun reported in May 2024 that the brigade was due to receive Rosa-RB low-altitude radars by the end of 2024, but I did not find an official unit-level confirmation of delivery; in late October 2025, iSANS reported a mobile low-altitude radar group from military unit 39872 on combat duty near Krichev, and rail observers recorded a 28-wagon brigade echelon to Ashuluk in summer 2025. These reports are plausible indicators of modernization, deployment, and training support, but they remain independently sourced rather than formally acknowledged by Minsk.
