WWII German Aluminum Army Visor Hat Eagle Insignia

 The Wehrmacht main uniforms, though there were so many specialist uniforms and variations that not all (such as camouflage, Luftwaffe, tropical, extreme winter) can be included. 

Since before World War I German and Austrian mountain troops had worn a visored "ski cap" (Gebirgsmütze) with turn-down ear flaps secured in front by two buttons. A version of this cap with longer visor, false turn-down, and slightly lower crown in olive cotton twill had been issued with the tropical uniform. In 1943 a similar cap in field-grey wool with a visor intermediate in length between the mountain and tropical versions was issued to all troops for field wear only; it quickly became the most commonly seen soft headgear at the front. Insignia was similar to that of the side-cap, although the eagle and cockade were both worn above the turn-up. A black version was issued to Panzer crewmen.
