The Brotherhood of War is a series of novels written by W. E. B. Griffin, about the United States Army from the Second World War through the Vietnam War. The story centers on the careers of four U.S. Army officers who became lieutenants in the closing stages of World War II and the late 1940s. The series is notable for the amount of attention it does not devote to combat. Rather than skipping forward, it follows the main characters though their peacetime service as the army evolves in the 1940s, 1950s and 1960s, particularly in the development of Army Aviation and the Special Forces.
