When I was active duty in the military and we had "cadets" there for their OJT once, we were told to salute them (enlisted ranks), but no one did. The day a sergeant-major salutes a cadet will be the day I suppose. I see the CAP as something that isn't even at the level of a cadet going through training to be an officer. CAP are not commissioned officers. That's an easy line to draw. If you want to have fun, when you see them move your hand up to scratch your nose.
