A number of design faults of the Tetrarch 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 Tetrarch effectively. The gunner or commander, in addition to his own duties, had to act as loader 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 Tetrarchs during combat would be almost impossible.
