Camp Allen: Camp Allen, is a small United States Marine Corps base in Norfolk, Virginia, a satellite of the Naval Station Norfolk.  In 1942 the Chief of the Bureau of Yards and Docks wanted the first Seabee training center close to an existing Naval training facility with Norfolk being chosen because of the available land that could be purchased.  On 25 March 1942 the Commandant of the 5th Naval District announced that the U.S. Naval Construction Training Center, Naval Operating Base Norfolk had been commissioned 4 days prior.  The base was named Camp Allen in memory of the CEC Captain Walter H. Allen founder of the naval construction regiment at Great Lakes Naval Training Center during WWI.  It is now home to both the 1st and 3rd Fleet Antiterrorism Security Team (FAST) Companies.  The base also houses a supply warehouse, battalion aid station, and a motor transport unit.

Service Squadron: A Service Squadron (ServRon) was a U.S. Navy squadron that supported fleet combat units.  Service Squadrons were used by the United States Navy from their inception in 1943 to as late as the early 1980s.  At the time of their inception during the Second World War they allowed the US Navy to operate across the vast reaches of the Pacific ocean for extended periods of time.  Service Squadrons created temporary forward bases to allow the naval squadrons to spend less time in transit and more time in the area of combat.  Ulithi, a small volcanic atoll in the central Pacific, is one such example.  Service Squadrons essentially created a major naval base near the area of operation.  With the naval base at Ulithi to refit, repair and resupply, many ships were able to deploy and operate in the western Pacific for a year or more without returning to a major port facility.  Among the vessels operating in service squadrons were tankers, oilers, refrigerator ships, ammunition ships, supply ships, floating docks and repair ships.  They provided diesel, ordnance, aviation fuel, food stuffs and all other supplies.  Equally important at places like Ulithi were the portable piers and floating dry docks which allowed many ships damaged by enemy action or Pacific storms to undergo repair without having to travel the thousands of miles back to a major US naval base.  Ulithi was as far forward from the US naval base at San Francisco as the San Francisco base was from London, England.  To have a fully functional major port in the middle of the Pacific was a significant aid to U.S. Navy operations.
