German Luftwaffe machine operators using an anti-aircraft MG-15 gun next to an airfield. The Luftwaffe used blue as his basic colour, with a uniform consisted of a blue-grey single-breasted, open-collared jacket with four pockets and flaps, white shirt and black necktie, blue-grey trousers, black leather boots and a blue-grey peaked cap, side cap or Model 1935 Stahlhelm. While on field service the jacket would often be worn 'collared up', without shirt or tie. This was applied to AA soldiers and field forces. The flying suit, however, typically consisted of a beige jumpsuit.
