From the days of the horse-drawn caisson to today's Humvee, Fort McCoy has played a vital role in the military readiness of America's armed forces. The only federal military installation within the state of Wisconsin, Fort McCoy has seen more than five million military personnel from throughout the United States pass through its gates since its founding in 1909. Fort McCoy exists today primarily because its founder, Maj. Gen. Robert B. McCoy, foresaw that the U.S. Army would need a regional site at which to train and maneuver and then dedicated himself to making that vision a reality. Fort McCoy's mission of supporting training and mobilization has remained constant from those early days on the McCoy ranch to the current global War on Terror. This book chronicles the illustrious history of Fort McCoy from the doughboys of World War I to today's soldiers supporting Operations Enduring Freedom and Iraqi Freedom.
