Sand Island Air Force Base, frequently referred to as simply Sand Island, is an Osean Air Defense Force base located on the eponymous island in the Ceres Ocean, west of Cape Landers. It is the former operating base of the OADF 5th Fighter Wing, 108th Tactical Fighter Squadron "Wardog". As Osea's westernmost outpost, Sand Island was at the forefront of hostilities between Osea and Yuktobania during the Circum-Pacific War: several consequential engagements took place over and around Sand Island.
