a training area for the 7th Light Infantry Division (based at Fort Ord), and as the home for the Training and Experimentation Command (USACDEC) (usually abbreviated as CDEC and later as TEC). The mission of CDEC was to evaluate new Army and Marine Corps weapons systems by providing a simulated Soviet Mechanized Rifle Company to act as the "OPFOR", or Opposing Forces. By this method, the Sgt. York anti-aircraft gun was found to have serious flaws, while the Marine's Light Armored Vehicle was validated. , the command is officially designated as the U.S. Army Garrison Fort Hunter Liggett with Parks Reserve Forces Training Area (RFTA) (aka Camp Parks) located in Dublin, California as a sub-installation. Base Realignment and Closure impact In its 2005 Base Realignment and Closure (BRAC) recommendations, the Department of Defense recommended relocating the 91st Division from Parks Reserve Forces Training Area to Hunter Liggett. In 2007, the Army created the Combat Support Training Center at Fort Hunter Liggett and ramped up training from roughly 300,000 man-days per year (predominately during the summer), to over 850,000 per year, year-round. While training was centered around Army Reserve units preparing for deployment, such was provided to all Army components (Active, Reserve, and Guard), and to Air Force, Navy, Marines, and even foreign commands (the Japanese Ground Self-Defense Force trained there in late 2007). Exercises held that first year included Pacific Warrior and Global Medic, which involved over 6,000 troops at Hunter Liggett, and connections to other units in locations across the nation. The Army installation's garrison commander relocated from Camp Parks to Hunter Liggett in early 2007, with oversight for Camp Parks and Army units and housing that remain at former NAS Moffett Field and B.T. Collins Reserve Center in Sacramento. Significant training infrastructure improvements were made including several Tactical Training Bases (TTBs - analogous to Forward Operating Bases), a wired "shoot-house", improvements to the hardened landing strip capable of handling larger Air Force transport planes, and a 7-mile live-fire convoy course, the US Army's only such training area capable of handing 360-degree fire up to .50 caliber. A new US Army Reserve Center was constructed and the 91st Division moved into their new Headquarters building in May 2009. On 11 September 2010 the new HQ was designated as the Master Sergeant Robb G. Needham Army Reserve Center after the first 91st Division combat casualty since WWII. Filming location Fort
