The Ehrenpokal was generally reserved for the lower ranks. It is rather unusual to find a Major with one, and the number of Hauptleute who held that rank at the time of the award are far and few between, too. Of the 10,375 Ehrenpokal awards made by the Luftwaffe, 99.3% went to Oberleutnante and below. Right from its inception, it was designed to fill the award gap below the DKiG so air crew Borkfunker, Bordmechaniker, Bordschütze, Bordwart as well as the lower ranking Flugzeugführer and Beobachter could be rewarded for outstanding performance or accomplishment. Only about 10% or less of the DKiG and RK holders seem to have also had the Ehrenpokal. It was never awarded to someone who already had the DKiG and/or the RK.
