Thanks to all who contributed to the original thread.This acronym list is fantastic, as a new Mishipman candidate (MC) mom (whose son is at NSI 3 right now) this is great, thank you!

The listing for Zero Deck is not correct, at least not at USNA.
Within Bancroft Hall, the "Zero Deck " is the nominal ground floor and more importantly is the lowest inhabited deck which means it is the lowest deck with midshipman rooms. All 8 wings have at least one Basement Level below the Zero Deck and they hold a wide variety of things including Barber shops, the Midshipman Store and many many other things. The basement level does vary above and below actual the outside ground level depending on the wing and 7th wing has two basement levels above outside ground which are below the zero deck.
