"Through the mud and blood to the green fields beyond". - motto for british tankers. The British Mark lV was the first tank to fight another tank and was used for the first time in mass numbers for an attack. A male tank was armed with 2 6-pounder guns and 3 8mm machine guns; and the females were armed with 4 .303 Vickers Machine Guns, one 8 mm Machine Gun. With a crew of 8, most tanks were lost by mechanical problems than being destroyed by the enemy.
