25th Air Support Operations Squadron

The squadron was first activated at Salinas Army Air Base, California in March 1942 as the 25th Observation Squadron.[1] The squadron's cadre came from the 110th Observation Squadron, a federalized unit of the Missouri National Guard.[1][2] Initially, the primary aircraft of the squadron was the North American O-47, although it flew a number of other aircraft as well.[1] In April 1943 it was redesignated the 25th Liaison Squadron and converted to light two-seater aircraft. primarily Piper L-4s, but also including Stinson L-5 Sentinel. The unit moved overseas in October 1943 aboard the Cape Mendocino to Australia in the South West Pacific Theater.[2]

After pausing briefly in Australia, the squadron moved to New Guinea.[1] There it operated primarily with L-5 Sentinels, flown by enlisted pilots. Some of these "sergeant pilots" were men who had washed out of pilot school, but had been given a chance to operate the light aircraft.[3] Beginning in February 1944, the 25th began participating in combat operations.[1]

In addition to their mission of spotting and aerial reconnaissance, the squadron was tasked with short haul transportation.[2] The capability of its light aircraft to operate from confined spaces earned A Flight of the squadron the nickname "Guinea Short Lines".[4] The flight moved forward to Saidor Airport.[3]

The squadron dropped supplies to units caught behind enemy lines and evacuated them, sometimes dropping tools so that these units could hack a landing zone out of the jungle.[5] In addition to the task of evacuating downed aircrew members, the flight flew night harassment missions behind enemy lines, dropping small bombs and other paraphernalia on enemy camps. The flight was called on in 1944 to rescue a downed Republic P-47 Thunderbolt pilot from behind enemy lines. In the course of this operation, and while the downed pilot was clearing an area for an L-5 to land in the jungle, the squadron was tasked to also evacuate 23 Indian soldiers, who had escaped from a Japanese prisoner of war camp and who had intelligence information concerning Japanese troop positions. Flying into the improvised jungle airstrip, the flight successfully returned all to friendly control.[3]

Shortly after this rescue operation, the flight was tasked with transporting fifty Australian commandos to Wantoat to attack a Japanese radio facility. Following the raid, four Japanese prisoners were returned, each sitting on the lap of an Australian in the back seat of one of the Sentinels.[3]

By the end of 1944, the 25th began operating in the Philippines, earning two Distinguished Unit Citations and a Philippine Republic Presidential Unit Citation for its actions there.[1] During the Philippine campaign, the squadron also trained pilots of the liaison squadrons of the 3d Air Commando Group, which had just arrived in the theater.[3] It remained in the Philippines until August 1947, although it was not manned or equipped after January. Although it moved on paper to Kadena Air Base, Okinawa in August, it was not again manned until October 1947. It remained with the occupation forces on Okinawa until being inactivated in March 1949.[1]

The squadron was again activated in July 1971 at Eielson Air Force Base, Alaska, as the 25th Tactical Air Support Squadron and equipped with the Cessna O-2 Skymaster.[6][7] In 1986 the 25th upgraded to the North American OV-10 Bronco, 1986–1989.[6] The squadron was inactivated in September 1989.[7]

Its most current period of active service in Hawaii began a little more than a year later in 1990, when it was activated as the 25th Air Liaison Squadron at Schofield Barracks. Three months later the squadron moved to Wheeler Army Airfield.[7] The unit has deployed in support of Air Force and Army missions.[8] The squadron is manned by tactical air controllers, a unique type of servicemembers—Air Force by service, but Army by trade, planning, communicating and facilitating the execution of close- air support for ground forces. To assist in their communication needs, the JTACs operate and maintain a complete array of equipment. Tactical Air Control is also one of the few jobs in the Air Force operates far forward on the battlefield.[9]

The 25th deployed to Afghanistan in 2006. They were located everywhere from headquarters to operations with company-sized elements, acting as the liaison for all air support that comes from all services and coalition partners. Their mission of calling in air support requires communication and planning. Planning includes advising leaders on the best ways to use air assets and coordinate so that close air support can operate safely on the battlefield with other indirect-fire assets, such as artillery and mortars.[9]
