i dunno. must refer to the GOMs. but there certainly is no
requirement to do so, even when one is in uniform outside. (unlike
recruits who are supposed to have their jockey caps on outside if
unsheltered). so there really is no reason for one to have his
beret on. he could just put it on his shoulder if he wants to let
the whole world see it, and THAT is already quite.. ermm.. weird.
