The whole thing is pretty authentic and really well done. I have it earlier also loved to watch, as the consequences on television ran. As will be dispensed with soft-focus and on (political) accuracy that you get today purposed at every German mission (ad nauseum).
It is also seen as the earlier "wild" conditions in some countries prevailed and how little has changed in the last 35 years it.
Well worth it for anyone who likes authentic films.
