Hang on a minute, let me think about this! So high command luftwaffe must have made sure before sending over millions of tonnes of bombs, that all the people on British soil had CSCS and PPE to be able to accept the bombs, and be competent in handling them! No!
They just sent them, we found them, and worked out how to disarm them by sending people in as Guinea pigs really, they wrote things down and used radio message to train the next Guinea pig! Same again really, they were trained in discipline, polishing boots, rifles and bayonets, not what to do with f***ing great unexploded bombs, but if they only had CSCS
