The Direct Air Support Center (DASC) is the principal United States Marine Corps aviation command and control system and the air control agency responsible for the direction of air operations directly supporting ground forces.

During amphibious or expeditionary operations, the DASC is normally the first Marine Air Command and Control System (MACCS) agency ashore and is usually categorized as the Ground Combat Element's (GCE's) senior Fire Support Coordination Center (FSCC). The DASC's parent unit is the Marine Air Support Squadron (MASS) of the Marine Air Control Group (MACG).

Marine Air Control Squadron 3 (MACS-3) was a former United States Marine Corps aviation command and control squadron. During its later years it also served as an operational test and evaluation squadron. Originally formed in World War II as Air Warning Squadron 12 (AWS-12), its original mission was to provide aerial surveillance and ground-controlled interception (GCI) for Marine Corps forces during amphibious operations. The squadron did not participate in combat operations during WWII however it did deploy and operate during the Korean War. In 1961, MACS-3 was transferred from the Fleet Marine Force to the administrative control of Air, Fleet Marine Forces Pacific in order to serve as the operational test and evaluation squadron for what was at the time, the largest research and development project in the Marine Corps - Marine Tactical Data System (MTDS). After MTDS testing was complete the Marine Corps recognized that it was not properly staffed to develop, test, and acquire new digital equipment. On 1 July 1970, MACS-3 was decommissioned and its structure and equipment were utilized to form Marine Corps Tactical Systems Support Activity (MCTSSA) at Marine Corps Base Camp Pendleton, California. Of note, MCTSSA does not carry MACS-3's lineage and honors.
Marine Air Traffic Control Units (MATCU) were United States Marine Corps air traffic control (ATC) detachments that provided continuous, all-weather, radar and non-radar, approach, departure, enroute, and tower ATC services at both garrison Marine Corps Air Stations and tactical airfields when deployed. MATCUs possessed Tactical air navigation systems (TACAN) and Ground-controlled approach (GCA) equipment which assisted Marine Corps, joint and coalition aircraft in conducting landings during inclement weather. During the Vietnam War, numerous MATCUs served throughout the I Corps Tactical region of South Vietnam supporting the III Marine Amphibious Force. Beginning in the mid-1970s, the Marine Corps decided to consolidate regionally aligned MATCUs into Marine Air Traffic Control Squadrons. The last reserve MATCU was decommissioned in 1980.
Marine Air Traffic Control Squadron 38 (MATCS-38) was a United States Marine Corps aviation command and control squadron responsible for providing continuous, all-weather air traffic control services for the 3rd Marine Aircraft Wing throughout the West Coast of the United States. MATCS-38 was formed by consolidating four, regionally aligned Marine Air Traffic Control Units under one flag to better integrate them with the Marine Air Command and Control System. The squadron was headquartered at Marine Corps Air Station Tustin, California and fell under the command of Marine Air Control Group 38. MATCS-38 was decommissioned in September 1994 and its air traffic control function were transferred to Marine Air Control Squadron 1. Since its decommissioning, no other squadron has carried the lineage and honors of MATCS-38.
