This area, chosen by General George S. Patton, was to become the training area for over 1,000,000 soldiers from approximately 400 units. The actual training was conducted in three maneuver areas covering approximately 18,000 square miles. These maneuver areas and camps are clearly marked on a large map in the right wing of the Heritage Center. The exhibits of the Heritage Center follow the history of the Proving Ground from Camp Laguna to the Korean War, Vietnam, Saudi Arabia, and Bosnia. A visitor can step into the Post Commander's office as it appeared in 1954; inspect the large array of shells and munitions; admire prize-winning models of military vehicles; study Army uniforms, equipment and photos from WWII up to the "21st Century Soldier;" and examine a vast array of photos and information on military vehicles, equipment and munitions that have been tested at YPG over the years.
