The book is an authoritative history on the Army Air Defense Artillery Branch on Fort Bliss, Texas. Fort Bliss in 1940 was a cavalry post located on the Texas border. The post itself occupied the sixth location of what had been called Fort Bliss. In the summer of 1940 a number of Army National Guard antiaircraft regiments were called to active duty to spend one year protecting American cities and territories from air attack. In September the first antiaircraft regiment, the 202nd Coast Artillery (Antiaircraft) Regiment, arrived at Fort Bliss. Over the next four years the post became an antiaircraft training center and finally the Army antiaircraft training center. After the war, Fort Bliss became the premier guided missile testing and training center for the Army. All of the Nike missile battalions deployed to protect American cities during the Cold War trained there. As time passed, Fort Bliss expanded to 1.1 million acres, one of the largest Army posts in the world. By 1946, the antiaircraft arm was the owner of Fort Bliss. By 1957, the post had become the Air Defense Center and School for the United States Army. This book is the story of that progression until the Base Realignment and Closure announcement in 2005. By 2011, the Air Defense Artillery Center and School will be located at Fort Sill, Oklahoma. This will end the era of Air Defense Artillery ownership of Fort Bliss, Texas
