What exactly are you supposed to be?
Name's right, Captain Vacuum!
In truth, it was an attempt to create a fictional battle dress uniform that a West German infantrymen might have worn during the 1950s-60s. The idea of using American military equipment (the helmet seen in the picture is actually the inner-helmet of an American steel-pot from Korea) in conjunction with German came from studying the typical uniform designs of Cold War proxy nations the day before...it was very common to see nations supplied by either the US or USSR utilize certain peices of the aforementioned's arsenal.
The picture itself was the result of an extraordinarily boring Saturday afternoon that forced me to catalouge my militaria collection. The picture is intended to be comedic, however. Notice, if you will, the model-esq pose and vacuum cleaner attatchment.
I suppose some explaination was needed for the picture, though. For those wondering, the jacket is a common 1988 West German field jacket.
