Been watching The World at War and have just been struck at the amount of variety in Nazi saluting. For example there's the familiar straight arm at 45Ë angle. then there's the straight arm parallel with the ground which has a limp-wrist variant also. Lastly there's the forearm pointed directly up with hand bent slightly rearward. Question: Was there a purpose for these differences or could they ust salute in whatever fashion tickled they happened to fancy?
