Major Michael Sadler MC MM
Both the Military Medal and the Military Cross.
Each means about the same thing. But, back then, one was for non-officers, one for officers. So, having both means having done the thing as a non-officer, become an officer, and done the thing again.
That’s, erm, impressive. And I’d doubt there are all that many who’ve achieved that double. Rather rarer than MC and bar I would have thought?
