Helmet cam footage from Azov's 3rd Assault Brigade shows a squad of infantry troops dismounting from armored personnel carriers near Russian trenches, only to become immediately engaged by accurate mortar fire in Kharkiv. The continuous barrage manages to wound at least one Ukrainian soldier. The mortar threat also forces them to begin their bunker clearing operation in a hasty manner. The threat is great. The mortar rounds landing above ground are deadly, but enemy troops are likely waiting in the underground trench network. The cameraman uses a weapons mounted strobe light to even the playing field, as sticking ones head in a dark tunnel after being in the bright outside causes momentary blindness. Multiple weapons and equipment are captured. The cameraman uses a captured Russian radio to taunt the enemy, and the Russians respond with their own verbal hostilities over the frequency.
