and established the 3636th Combat Crew Training Group at Fairchild in April 1966 to conduct survival training at its new location. However, all aspects of SERE training were not unified under the group. By the early 1970s, Pacific Air Forces was running the Jungle Survival School at Clark Air Base, Philippines, while United States Air Forces Southern Command had a Tropical Survival School at Howard Air Force Base in the Panama Canal Zone. Alaskan Air Command had an Arctic Survival School at Eielson Air Force Base, Alaska and Tactical Air Command operated a Water Survival School at Homestead Air Force Base, Florida. In April 1971, these schools were brought under one hand, and the 3636th CCTG was upgraded in status to the 3636th Combat Crew Training Wing. Squadrons were organized to conduct training at Clark, Fairchild and Homestead, while detachments were established at the other locations including with Operation Red Flag at Nellis Air Force Base where Detachment 2 ("Det 2"), 3636 CCTW, was established to conduct evaluations and provide training of personnel assigned or Temporary Duty (TDY). Det 2 conducted with TDY air units, simulated Search and Rescue Exercises (SAREXs) in Northern Nevada and at CFB Cold Lake, Edmonton, Alberta, Canada, from 1976 to 1985. It was at Detachment 2 that the Combat "Desert" Survival Course was written and tested. This course would be formalized by the 3636CCTW and eventually this would cause a major change in the USAF Survival Training Schools emphasizing "Combat Survival" instead of "Global Survival". In 1985 Det 2 was discontinued and its personnel were assigned to the Tactical Air Command at Nellis Air Force Base or transferred back to the 3636th CCTW. Detachment 2, 66th Training Squadron, was located at NAS Pensacola, Florida in 1993 where it conducted the Parachute Water Survival Course for aircrew flying aircraft with ejection seats jointly with the United States Navy. The separate Air Force School at Homestead was discontinued. Students attending SERE training at Fairchild, were sent on temporary duty to Pensacola for this training. The school was moved to Fairchild in August 2015, and combined with the existing non-ejection water survival course to avoid the expenses associated with student travel. Courses circa 2016 The 22d Training Squadron conducts Combat Survival Training (CST). The 66th Training Squadron conducts the SERE Training Instructor Course. This is a five-and-one-half-month program designed to teach future survival instructors how to instruct aircrew
