The attorney I spoke about in a previous post was first sent as a JAG, 3 yrs later because he was promoted he was sent as a commander of a squadron that was in charge of rebuilding schools, absolutely nothing to do with the law, just happened to be his rank and he drew the short straw.
This guy was the son of an O6 Army officer, and the son was an attorney. Like Sprog stated the military has the right to do to the needs of the service. If you are wondering if he is still a reservist, he is. He stayed because now he is so close to points for a retirement in the reserves it is not worth it for him to leave. He spent his first 15 yrs never going anywhere, the last 4 he has been deployed for almost 1/2 of those 4 yrs.
Bullet as an ADAF officer, was deployed to Iraq when he was at the Pentagon working a desk. The Army said to the AF we need a person with XYZ qualifications to go to Iraq with the Army. AFPC laughed in their face believing that the requirements were so specific that there would not be one AF officers with all of their needs, lo and behold, there was exactly 1, and it was Bullet! His orders were cut and he was gone in 10 days.
Granted that is the ADAF, however, my point is even if you know the job is going EM, that doesn't mean you are safe because even the little things you do in EM can mean you are their perfect candidate for their needs.
