I have heard of stories of allied soldiers being executed on the spot straight after being taken prisoner by the Germans during WW2 because the've been found to have Germanicon equipment on them. This may have been items such as a pistol or weapon, a German watch or other personal possessions that have obviously been taken from a German prisoner or casualty. These items would obviously have come to light when the allied prisoner was initially searched after capture.

A similar situation arose with the F/S Commando knife, if taken prisoner by the Germans and if caught in possession it was highly likely to result in execution. For some reason the Germans don't appear to have understood that it wasn't only Commandos who were issued the knife. I have heard of the knife being discarded when capture looked likely.
