DO? Not us dude, I do know some former cadre with those intials, haven't seen them since 02 though.

Great point on the locker, that is an ideal situation, considering the requirement for trained guys on every team, and SWSs being an MTOE item (open source info folks) it really should be treated the way we do everything else....a quarterly refresher is ideal. Shit, we jump every quarter, and I can guarantee SWSs get used more than static line parachutes in a combat situation.
