Advanced operations base

In special operations, a small temporary base established near or within a joint special operations area to  command, control, and/or support training or tactical operations. Facilities are normally austere.  The base may  be ashore or afloat.  If ashore, it may include an airfield or unimproved airstrip, a pier, or an anchorage.  An  advanced operations base is normally controlled and/or supported by a main operations base or a forward operations base.
