No Wider War is the second volume of a two-part exploration of America's involvement in Indochina from the end of World War II to the Fall of Saigon. Following on from the first volume, In Good Faith, which told the story from the Japanese surrender in 1945 through America's involvement in the French Indochina War and the initial advisory missions that followed, it traces the story of America's involvement in the Vietnam War from the first Marines landing at Da Nang in 1965, through the traumatic Tet Offensive of 1968 and the gradual Vietnamisation of the war that followed, to the withdrawal of American forces and the final loss of the South in 1975. Drawing on the latest research, unavailable to the authors of the classic Vietnam histories, including recently declassified top secret National Security Agency material, Sergio Miller examines in depth both the events and the key figures of the conflict to present a masterful narrative of America's most divisive war.

The M551 Sheridan is often referred to as a light tank, but in actuality it was an armored reconnaissance/airborne assault vehicle. The M551 was designed to be a lightweight, amphibious, air-droppable vehicle armed with a massive 152 mm gun that doubled as a rocket launcher. The gun launcher was designed to fire the MGM-51 Shillelagh antitank missile, or 152 mm conventional rounds with a combustible cartridge case. The vehicles saw extensive use in Vietnam, Operation Just Cause in Panama (where they saw their only combat air drop), and Operations Desert Shield and Desert Storm. The Sheridan ended its service with the US Army masquerading as Soviet Bloc vehicles at the National Training Center. Through dozens of archival as well as detailed photographs of some of the finest extant examples of these vehicles, the Sheridan is explored, and its history explained. Part of the Legends of Warfare series.
