Notes
^ Direct U.S. involvement ended in 1973 with the

^ (33)The term "Persian Gulf War" means the period beginning on August 2, 1990, and ending on the date thereafter prescribed by Presidential proclamation or by law.
38 U.S.C.
§ 101
^ The Bay of Pigs invasion was conducted by
Brigade 2506 , a group of
Cuban exiles recruited and equipped by the CIA as part of a
covert operation , and trained by instructors from the CIA and U.S. Army Special Forces, U.S. Air Force, and Air National Guard.
[15] The botched invasion took three days: Americans were initially not authorized to participate in the invasion. However, on the last day of the failed operation (April 19, 1961), U.S. air support was authorized, and eight
Alabama Air National Guard members flew into Cuban airspace.
