Many of the horribly-vulnerable Light Tank Mk VICs went to France in 1940 largely with-out armament, with the holes in their turret fronts plugged with plywood, and with their crews armed only with pistols and rifles. Some met the Panzers in this condition. Like the Sherman, the Covenanter and early Cromwells had hatches for the driver and co-driver that could not be opened when the turret was turned to certain angles. This greatly reduced a hull crewman's survival chances if the vehicle caught fire. Also, the auxiliary MG turrets fitted to some early British cruisers and Crusaders were officially condemned as being "unfit for human habitation" even in cooler European conditions, let alone the desert heat, especially as the British BESA MG produced more (toxic) fumes than other types in use. In addition, many early Crusaders had armour of very poor quality compared to US armour plate. There is evidence that some Churchills had poor quality armour, and in Tunisia cases of the steel flaking badly when penetrated were reported. Although some Churchill VIIs were available by D-Day, they were comparatively rare outside Crocodile units not just because of slow output and a desire to use up older types first, but because a number had to be withdrawn for field modifications in July 1944 due to the poorly secured glacis plate armour that could fall inwards under the shock of impact. Some Cromwells too suffered from sub-standard armour made by an inexperienced manufacturer, though this batch of vehicles at least saw no action.
