The promotion of a military physician from Captain to Major is automatic. There is no review. If the doctor is not at Leavenworth, he is promoted.
No doubt about it. I've seen officers and SNCOs get promoted smack-dab in the middle of an Article 32 investigation, even a court-martial a few times. Once a FITREP is submitted, it comes down purely to time-in-grade, time-in-service, MOS and demand. That's it.
