The lessons of the campaign were studied by military planners prior to amphibious operations such as the Normandy Landings in 1944 and during the Falklands War in 1982. The lessons of the campaign influenced US Marine Corps amphibious operations during the Pacific War and continue to influence US amphibious doctrine. In 1996, Theodore Gatchel wrote that between the wars, the campaign "became a focal point for the study of amphibious warfare" in Britain and United States. In 2008, Glenn Wahlert wrote that Gallipoli involved "all four types of amphibious operations: the raid, demonstration, assault and withdrawal".
