San Diego County in southern California holds one of the United States Marine Corps’ largest bases, Camp Pendleton. It is the major West Coast base and serves to train expeditionary forces and is a prime amphibious training base. It was established in 1942 to train marines for combat in World War II and soon became a permanent installation. A new chapter has now been written in the camp’s rich history of training America’s elite warriors. Camp Pendleton is now a producer of renewable energy.
