Obviously things can be warry as well. A flag with 40 bullet holes in it is more warry than a cherry one coming out of the packet. A Challenger with 20 or 30 RPG hits, missing most of its ariels and covered in scorch marks will have a crew that justifiably feels that they are without doubt NOT combat virgins.
Should not be confused with being Gung Ho, being warry and gung ho are entirely different.
Any combat virgin can be Gung Ho, particularly Spams.
