Base code
Stellar systems may have bases for military forces, the Navy, the Scouts, or for other arms of interstellar government.
If a base is present, it should be marked in subsector maps, and the UWP. Other types of bases, e.g. army bases, merchant exploration or trade bases, and defense establishments may be indicated.
A Navy Base (code N) is an Imperial Navy facility.
A naval depot(code D) is a large Navy Base used to support large-scale Naval activities. There should be no more than one naval depot per sector.
A Scout Base (code S) is a Scout Service facility.
Scout Way Stations (code W) may be found at selected worlds along communication routes, and are never co-located with naval depots. These bases serve as points for veterans to renew acquaintances, to find potential patrons, and to scrounge or buy surplus equipment of use to them.
A joint Navy / Scout Base (code A) are facilities that are co-located with each other.
A joint Navy Base / Scout Waystation (code B) is a Navy Base with a Way Station
