I'm an MS4 in the military who matched FP but have since have had a change of heart. I've done an EM rotation and love it. I also love GS. In the military, you may complete your internship, then do an operational tour that counts as your payback time, then choose to either complete a military residency, or a civilian one. Say, hypothetically, I completed my military FP internship, served my time doing an operational tour, then got out of the military, would I be able to start over and complete a civilian EM or GS residency without any roadblocks, assuming I matched into a civillian GS or EM program? I've heard something about pay issues if you've completed one internship then start a different one, but I'm very unclear on this. If anybody could shed some light on this, I'd much appreciate it.
