I found this commercial booklet from the Reliance Manufacturing Company, a parachute manufacturer. It is not dated, but from the text inside it is clear that it must be from 1941 or 1942 at the latest. It discusses the exploits of the Russians and Germans and it speaks of the newly formed ‘winged infantry’ and speculates on how this force might be employed in the war.

Fun fact: Reliance also manufactured underwear shorts for the Army.
