One of history’s most famous fighter tacticians and originator of the famed "Thach Weave," Captain John S. "Jimmy" Thach commanded USS Sicily (CVE-118) off Korea during 1950-1951. During this tour of duty he turned his attention to studying the tactics of close air support. This speech, which was delivered by Thach in November 1950, details Marine Corps close air support missions flown from the flight deck of Sicily during the early months of the Korean War.
