The war on terror has been rough on American troops, with record numbers of them overseas and in combat. But at the same time, record numbers of troops are staying in the military, and more volunteers are trying to join as well. The result is that the U.S. Air Force finds that it has about 16,000 more people (12,700 enlisted and 3,900 officers) than it is authorized, by law, to have. The air force has to shed this excess by Sept. 30, 2005. This will be done by allowing those who want to get out of their current service obligation early, to do so. Another option is to transfer to the reserves. Those who are eligible may also transfer to a job area where there is currently a shortage, which means one less recruit is needed. If not enough people volunteer to leave, then there will be a RIF (Reduction In Force), which is what the military calls a layoff. 
 
 Not everyone in the air force is at risk for the RIF. Not everyone is eligible for the early out or transfer to the reserves either. The job categories listed below are the ones that are currently critical. Not surprisingly, these jobs are either the most dangerous or the most technical. The air force is calling this entire process "force shaping."
 
 Air force job code is followed by name of the job.
