To the poster..if you've expressed your sentiments about getting out ASAP you may have shot yourself in the foot. According to the military dentists that I've talked to that's definitely something that you do not want to do. I was told that you'll pretty much get the short end of the stick when it comes to base selection and other requests that you may have. Might be from personal experience, but perhaps krmower can shed some light about this?
Also, while I commend you for taking the military scholarship and serving (thanks for service).. did you research anything aside from the fact that they would pay for school? You signed a pretty legitimate document and you don't even know what the obligation entails or could potentially entail.
My expectation is that the assignments officers would treat people equally. With over 400 general dentists to coordinate jobs for, I don't know of any way they would have to track those who want to get out. Dentists coming in don't have to declare what their career plans are so this should not be considered/known. When the assignment officers make assignments, there are some categories of individuals who will get preference:
1) Individuals selected for a specialty program will go to the base where the program is and work as a general dentist while they are waiting for the program to start (unless they start immediately).
2) Individuals who have special considerations (family members with special medical needs or a compassionate issue i.e. parent with terminal illness, etc...).
3) Spouse that is military - Army or other service
4) Individuals coming back from overseas assignments or who had made other deals prior to taking an assignment (they agree to go somewhere where there was a need in exchange for someplace they want)
5) Individuals going to TOE units (combat units - special forces, brigade dentists, etc...)
6) Everyone else
As far as how individuals are treated - YMMV. If I was a Commander and knew that someone was getting out I would use that when deciding how to spend training funds...probably not send that individual to do things that someone else that was staying in wanted to do (forensics, EFMB, Airborne, Air Assault, Combat Casualty Care Course, nominate for certain awards, etc...).
I can not state how another dentist would view/rationalize an individual getting out. I would hope that all individuals would be treated equally i.e. a specialist would help and mentor someone getting out just as they would someone staying in - that's my hope/belief at least.
Even if I had plans on getting out, I would work hard and try to do my part and not burn any bridges. I would minimize negative comments towards the military realizing that I may need to request LORs from dentists that I work with should I want to apply for civilian training, or if I needed references for jobs that I may be applying for.
