Second point is that from my understanding Soviet airforce and army used the same uniform? I remember an ICM 1/48 set labelled as soviet pilots and aircrew that was also sold as a set with a tamiya GAZ as generic Soviet officers?
Soviet AF and Army really used the same uniform, BUT there were 2 differences:
1. different color of edgings (airforce - blue, infantry- red, armour-black etc).
2. Special cockade of airforce on the top of service cap
