Germans pioneers wore white uniforms? That sounds like the worst possible colour for digging ditches, recovering tanks or camouflage (if it isn't snowing). Why would they do that? Did Hugo Boss do the design?

A prisoner’s uniform needs to be cheap, distinctive, and easy to spot it doesn’t need to be clean.
It’s a play on words, and the involuntary nature of service in the German military at the time.
