In March 1975, Island Commander Major Bruce R. Hoon was contacted by Pacific Air Forces (PACAF) and ordered to prepare Wake for its new mission as a refugee processing center where Vietnamese evacuees could be medically screened, interviewed and transported to the United States or other resettlement countries. A 60-man civil engineering team was brought in to reopen boarded-up buildings and housing, two complete MASH units arrived to set up field hospitals and three Army field kitchens were deployed. A 60-man United States Air Force Security Police team, processing agents from the U.S. Immigration and Naturalization Service and various other administrative and support personnel were also on Wake. Potable water, food, medical supplies, clothing and other supplies were shipped in.
