The United States Marine Corps came into its own in the Pacific Islands campaign against Japan in World War II. From Guadalcanal to Okinawa, US Marines formed the tip of the spear as Allied forces sought to push the Japanese back to their Home Islands.

This fascinating study tracks the deployments of the various Marine divisions throughout the war and explains their composition, but also goes deeper, to detail the individual regiments - the focus of the marines' identity and pride. It explains the organization of the Marine infantry regiment and its equipment, and how they evolved during the war. The marine infantryman's evolving uniforms, field equipment and weapons are illustrated throughout using specially commissioned artwork and detailed descriptions to produce a fitting portrait of the US military's elite fighting force in the Pacific.
