Ukraine’s Unmanned Systems Forces (USF) have executed a multi-target drone strike deep within Russia’s operational rear in the Zaporizhzhia region, inflicting heavy losses on three Russian units preparing to rotate to the front lines, Robert “Madyar” Brovdi, commander of the USF, reported on Facebook. Precision blitz at the “Vostochny” testing grounds Ukrainian drone units completed a nocturnal interdiction operation on the night of June 12.

According to Brovdi, the facility was actively housing and training personnel from three notorious Russian military formations, all of which are deployed to fight against Ukrainian forces along the active Huliaipole axis. Among them is the Kamchatka 40th Naval Infantry Brigade, a marine formation that spent over a year spearheading catastrophic, unsuccessful assaults on the fortress city of Vuhledar, depleting the majority of its original combat personnel on the approaches. The camp also hosted the 1461st Regiment of the 36th Army, which functions as a mobilized infantry regiment drawn primarily from the Republic of Buryatia. Finally, training ground assets included the 1466th Regiment of the 5th Army, a unit consisting of raw recruits from Primorsky Krai. In 2023, due to extreme pressure from commanders to engage in “meat assaults” in the Zaporizhzhia sector, a Russian company commander shot the regiment’s reconnaissance chief, callsign “Mustang,” at a command post before turning the weapon on himself.
