The US Marine Corps has achieved an almost mythical status as the very best the American forces have to offer. Tom Clancy takes the reader on a tour of the Corps and its training, technology and people. The book describes the tools of the Marine Expeditionary Unit, including the AAV-7 amphibious personnel carrier, the Wasp-class assault carrier and Harrier II attack jet. It also examines the role of the Marines in the present and the future.
