Marine Air Group 25 and Scat William M Armstrong

Marine Air Group 25 was a pioneering combat air transport unit that entered overseas service during the Guadalcanal campaign in September 1942, helping to achieve the first American offensive victory of the war in the Pacific. It quickly gained fame for its rapid delivery of vital supplies and its lifesaving evacuation of casualties. During the fight for Guadalcanal, Marine Air Group 25 became the nucleus of the joint-service SOPAC (South Pacific) Combat Air Transport Command, or SCAT, partnering with troop carrier and medical units of the US Army Air Forces. SCAT would continue to play a crucial role in subsequent Allied operations throughout the Solomon Islands, including the battles for New Georgia and Bougainville. After SCAT was dissolved in February 1945, Marine Air Group 25 continued its mission in the Philippines and then Northern China until being deactivated in 1946. In 1950, the group was reactivated, seeing further service during the Korean War.
