Lieutenant David McIntyre served with USAF special operations Para-Rescue for two tours before being folded into the Black community. After a single duty station with Task Force 141, he was offered a position on a experimental unit testing the capabilities of an unknown aircraft. This craft was the prototype X-302, which allowed him to be briefed on the Stargate Program. He formally requested transfer to an active SG unit, and was allowed a trial deployment with SG-17. His value was recognized as a tactical asset and was assigned to SG-19 for a single tour, then to SG-13 to replace combat loses. After the slightly over dramatized training event involving a squad of new recruits and SG-1, he showed promise assisting the in evactuation of the SG Team under fire during that training exercise., Lieutenant McIntyre felt he was ready for more of a challenge and submitted his request to volunteer for the Phoenix project to Colonel O'Neill. Cake was promised by the Colonel, and Lieutenant McIntyre packed his bags for new adventures.
