I would say that the vast majority of gliders that those Soldiers encounter are going to be from the WWII era. The US army stopped glider training shortly after WWII and the medal or badge that was being asked for to satisfy the Pilots or to the Soldiers flying in them were wanting a badge and sure enough the US Army made then and these I read were worn proudly. I guess if you lived through the transportation of being in one. I can see why they were worn proudly.
