I used to laugh at the madness that was COs rounds of the boat.
For a SSBN spread over 3 days.
Day 1 back aft = all their extra "useful" shit moved to the MC until rounds complete
Day 2 MC = all their extra very useful shit moved to AMS2 and
Day 3 Fwd = all their crap moved to the MC. Sometimes they even remembered to take it back.
