Bit of an esoteric one, but someone's got to know. I've seen pictures from the Viet Nam era with US Army personnel wearing Class A's without ribbons, just qualification badges, i.e. CIB, Jump Wings etc. First came across this when putting together a presentation using a pic of Lt Calley (see below), but also noticed SSGT Sadler (of Green Beret fame) singing on V with just the CIB and various wings up, but sans ribbons so I guess it's not just for those being Court Martialed. Any idea why they would have been worn without ribbons and if this is still done?
