Starting in the fall of 1952, the Navy's Cherokee strikes together with a series of Air Force "air-pressure" strikes resulted in intense US Air Force-US Navy BAI operations that did much to hamper Communist tactical mobility and eliminate the supplies that North Korean and Chinese Communist forces had been able to accumulate behind the front.
