Squadron Leader Douglas Bader DSO (front center) with some of the Canadian pilots of his Squadron, 242 (Canadian) Squadron,
grouped around his Hurricane fighter aircraft at Duxford, September 1940.
For guard duty, as a collective equipment, the Wehrmacht had a model of felt overshoes with wooden sole worn over the regulation boots for insulation purpose as well as an oversize variant of greatcoat with a huge colar to wear over the regular greatcoat.
My father in law (11th Colonial Engineers Regiment) remembers using them as captured equipment also for guard duty during the winter of 44. When relieved by the replacing sentinel, he had to pass him the boots and coat. By this date, because of the climate the poor Africans of the regiment had for long been regrouped at Marseille and repatriated in Africa, being replaced by metropolitans from the Resistance.
Coincidentally, I took a photo of an F6F-5 Hellcat in those the same markings as aircraft #32 shown. It is an aircraft that is part of the Flying Heritage Collection Museum at Paine Field, WA, the museum formerly owned by Paul Allen.
