However, when an "action is reported by the 9xx PTIs" it represents a "loss to the Air Force strength." In other words, despite the fact that Bush had almost eight months left on his six year Military Service Obligation at the time, Texas Air National Guard officers were signaling that Bush was essentially worthless to the Air Force, and should not even be retained in the "Ready Reserves" for call up in the event of a national emergency.

The fact that Bush was discharged from the Texas Air National Guard under a Personnel Transaction Identifier used to denote a reduction in total Air Force strength means Bush was considered not merely “useless” under present circumstances, but of no possible use to the Air Force at any point in the future. PTI 961 meant that Bush was unfit for service in the United States Armed Forces, and that there was no point in keeping him around in case of a national emergency.
