Roland Marichal shared these photos with me from a very special 1942 and 1943 dated publication of the Luftwaffe. It was found in Belgium. It describes the uniforms, weapons, equipment and aircraft of the allied airborne forces.
Much of this report contains information about equipment that would never be used against the Germans. We see photos of the first type of jump suit (only used in training), a Reising SMG (USMC-issue and never used in the ETO), airborne troops with bicycles and skis in dropping containers… Also note the large leather reinforcement patches on the M1942 jump suits, which were only used for the Sicily invasion.
The level of detail is quite astounding though, given the allies had only formed actual paratroops since 1941 (and experimental units as early as 1940).
Loose segments describe the landing vessels that the Germans thought would be used by glider troopers for the allied invasion.
