Assault from the sky

"This work describes U.S. Marine Corps helicopter operations, including their actions and evolution, throughout the Vietnam War. The book is divided into parts spanning the three stages of the Corps' combat deployment: 'Buildup (1962-1966),' 'Heavy Combat (1967-1969),' and 'The Bitter End (1975).' Each part includes chapters devoted to 'telling the story' of Marine helicopters from the individual to the strategic level"--Provided by publisher.
