I'm not aware of that, but I do know we will sponsor our own people to take specialties, and in only a few areas. Surgery, orthopedic surgery, and psychiatry are the only three I know of offhand. We will take our own people, and this is predictably where we have the highest success, of course. If you take military physicians and send them back to school to become psychiatrists, then if they understand the culture, they're inherently much more valuable.
Really, it's out of my area. I don't know who could answer that. Perhaps the surgeon general could answer your question better than I can, sir.
