Yes, I do. I spent 6 years in Special Forces and on Special Operations. MD's do NOT go on combat operations.
You're right -- he almost certainly did not because there is nothing on his uniform that would show he was personally and directly involved in active ground combat operations. He's got a Bronze Star and Navy Comm but neither has a V. However, he was stationed in Fallujah during the surge and directly involved with prisoner interrogations, etc., and likely heard gunfire more days than he did not.
So yeah, that's not the same as putting your ass out there on the front lines. But it's also a lot more than just sitting at home fat, dumb, and happy in front of the TV, where you don't have to worry about IED's, snipers, or random shelling on the drive home from work.
