Don't know what percentage of winners are medics, but some are.

I agree that their heroism is no less than that of the others, and maybe even more.

Some pacifists during wartime enlisted as battlefield medics. Men and women of iron principles and patriotism who say "I won't kill for my country, but I'm willing to die for it." There should be some kind of medal for that alone.

On the list linked to above, I know for a fact that at least Desmond Doss and Thomas Bennett are in that category. When Truman awarded
Doss the Medal of Honor, he said that meeting Doss was a bigger honor than being President.
