This Deck is one level lower than the bridge and has three main sections. The officer ready rooms, main security station, and the ships small arms armory. The front four ready rooms are for the First Officer, Tactical, SenCom, and COS. The other 6 offices are shared by the ships other more junior officers who do not have their own ready room on their assigned department area. (For example the Captain and Bridge officers ready rooms are off of the bridge, the CE has her office in Main Engineering, the Com officer and Sen officer have their offices with their department, Weaps has his office in Fire Control, the CAG has her office off of the flight deck, etc.) So the Junior officers left would be the Quartermaster and others who have broad responsibilities on the ship that do not contain them into one area. The rears section of this deck is used by security. The security station is resposible for keeping tack of guard and trooper movements and to watch sensitive areas. The small arms armory is where all character scale weapons are stored and locked. Just outside of this armory is a staging area to prepare armor and equipment defore using. The Mech shop on this level has all the technicians and tools to do most repairs on weapons and armor. Like most decks it has additional areas for storgae, ship systems, and the rear mounted escape pods.
