The helicopter came on the scene too late to play other than a minor role in the Second World War but by the Korean conflict the Bell H-13 Sioux, OH-23 Raven, and Sikorsky H–19 Chickasaw were in service.It was in Vietnam that the US military helicopters really came into their own and the best known were the Bell UH-1 Iriquois (known as the Huey), the Boeing CH-47 Chinook, and the massive CH-37 Mojave. The USAF combat search and rescue Jolly Green Giant was indispensable.Attack helicopters have evolved from the early Huey Cobra or Snake and the Boeing AH-64 Apache in the late 80s to when the Sikorsky UH-60 series became the military general purpose chopper.All these formidable aircraft and many more are covered in detail in this superbly illustrated and comprehensive book.
