Orick is a small Californian timber town that was earlier invaded by the Chimera after the town was hit by a barrage of Spire missiles from Chimeran warships in July 23, 1952. The occupied town posed a threat to the nearby city of San Francisco forcing SRPA forces including the special commando team, Specter Team, to cleanse Orick of Chimeran forces during Operation Green Eagle. However, Orick and its surrounding area were still under Gray territory.
During Daedalus's invasion of America on May 15, 1953, Sentinel team Echo damaged a Chimeran warship in San Francisco and forcing it to retreat and stall over Orick. Once SRPA and Echo Team arrived to Orick, the entire vicinity was heavily defended by Chimeran forces including Chameleons lurking in the redwood forests. Echo Team managed to bypass the defenses, boarded and destroyed the warship.
