The 66th Air Force Unit (also known as Galm Team) was a squadron formed in January 2018 by BlazeWardog016 and ChopperWardog008 following their removal from the Special Armed Response Force. Their original stated intent was to stop a potential conflict between SARF and the Brotherhood of Honor. Afterwards, the 66th flew occasional combat air patrols in and around Madobe, seeing action in combat every so often. After a half-year of inactivity, they re-emerged with new pilots, many of which came from other games such as War Thunder.
In 2019, the squadron underwent a leadership change when Blaze accepted a lower position as XO, with Vertex becoming Galm's new CO. In July 2019, Blaze left the squadron on bad terms and became a member of the short-lived Ransom Squadron. Shortly after this, the 66th AFU was radically reformed under the leadership of Vertex to become the 2nd United Combat Wing. From this point to November 2020, 2UCW's fleet consisted of aircraft which were re-badged from the former Galm, before UltraViolet created a new HQPGAC-based fleet for the squadron; the original Galm-based pack was retroactively labeled as the 2UCW "legacy" fleet.
