Question: What superfund site is the base for the "Snipers" Marine Corps squadron
Context: Air Warning Squadron 8 (AWS-8) was a United States Marine Corps aviation command and control unit that provided aerial surveillance and early warning of enemy aircraft during World War II.  The squadron was activated on 3 March 1944 and was one of five Marine Air Warning Squadrons that provided land based radar coverage during the Battle of Okinawa in 1945.  AWS-8 remained on Okinawa as part of the garrison force following the Surrender of Japan.

To date, no other Marine Corps squadron has carried the lineage and honors of AWS-8 to include Marine Air Control Squadron 8 (MACS-8).
