Aren’t there regulations stipulating from branch to branch of service what citations and ribbons can be worn and when? And wouldn’t something like a CIB be reserved for a Class A Dress Uniform?
I confess that I don’t know the answer to that. If a person is awarded a good conduct medal or any other medal in the Navy or Marine Corps, and enter the Army or the Air Force, those medals may be worn. I would think that would also apply to CIB, parachutist badge, etc.
They have subdued ones that are worn with the ACU’s
