 A number of design faults of the <unk> were revealed through its operational use . Its size limited the possible crew to three , a driver in the hull and a gunner and commander in the turret , resulting in too few crew members to operate the <unk> effectively . The gunner or commander , in addition to his own duties , had to act as <unk> for the 2 pounder , which caused delays in combat . A report on the tank written in January 1941 stated that as the commander had to both fight and control the tank , controlling a troop of <unk> during combat would be almost impossible .
