Footage of an attack by two Ukrainian FPV drones on a Russian T-72B3 tank, this is a modernization of the tank created in 2011. FPV drones were equipped with warheads from RKG-3EM hand-held cumulative grenades; the RKG-3EM series grenade is capable of penetrating up to 220 mm of armor. RKG-3 grenades were actively used in the Soviet army before the advent of the RG-18 grenade launcher. Reportedly, this attack occurred in the Krasnolimansky direction, where two tanks stormed a stronghold of the Ukrainian army; for an unknown reason, the grenades mounted on the drones did not work. The video has been shortened.
