Camp Parks, also known as the Parks Reserve Forces Training Area, is home to the Army's 91st Division, and has training facilities for reservists. More than 250 units representing 20,000 military personnel in the Bay Area make use of the installation.
It was constructed during World War II and commissioned in 1943, according to the U.S. Army Reserve.
