Video from Russian military personnel, where soldiers, despite the ban on the use of alcohol and drugs, got drunk on fire water in the dugout. Because of their rash actions, a grenade exploded in the hands of one of them. Consequences: some died, some became disabled for life.
You see, Ivan, we explode grenade in controlled environment to develop resistance to grenade on the battlefield.
