asked the Secretary of State for War whether he can give the number of casualties, fatal and otherwise, in the tank, armoured-cars, and other mechanised units during the last 12 months; how many of these were caused to the men actually in the vehicles; and whether any form of defensive clothing and crash-helmets has been provided?

I regret that the information asked for in the first two parts of the question is not available. A crash- helmet for tank crews was designed, but was found unsuitable in certain respects. Trials are now being carried out with another type, which it is hoped will be suitable.
