I'll go with General George C Marshall, at east as one of the most distinguished.
"In war he was as wise and understanding in counsel as he was resolute in action. In peace he was the architect who planned the restoration of our battered European economy and, at the same time, laboured tirelessly to establish a system of Western Defense. He has always fought victoriously against defeatism, discouragement, and disillusion. Succeeding generation must not be allowed to forget his achievements and his example."
--Winston Churchill
"His standards of character, conduct, and efficiency inspired the entire Army, the nation, and the world. To him, as much as to any individual, the United States owes its future. He takes his place at the head of the great commanders of history...The more I see and talk to him the more certain I am he's the great one of the age. I am surely lucky to have his friendship and support."
--Harry Truman
"Americans have never been so deeply indebted to any other soldier."
--Dwight Eisenhower
