This typewritten instructional memorandum, "Deflection Shooting," was issued by Marine Fighting Squadron 112 while forming at MCAS Santa Barbara, California, during World War II. It details the five gunnery approach runs - Over Head, High Side, Low Side, and Head-On from Above and Below - that Marine fighter pilots were required to master before entering combat. Preserved among the personal papers of Marine aviator Pat McAleer, the document illustrates the rigorous technical training that prepared Marine fighter pilots for aerial combat in the Pacific.
