Serhii Vasich, another tankman of the 14th Brigade, managed to shoot a Russian tank from the first shot. One after another the occupants of the tanks were caught in fire. Russian infantry started to run away, soon they spotted the position of the Ukrainian tankmen, and called for artillery backup. Manoeuvring the Ukrainian's tankmen destroyed the enemy.
