James Stewart held the rank of Brigadier General in the US Air Force Reserve. However, it could be argued that Ronald Reagan would be your answer. He didn't achieve the highest rank in the military per se, but he did become Commander In Chief of the Armed Forces when he became President of the United States.
The highest rank in the Marines, by title and rank, is the Commandant of the Marine Corps. The position is currently held by 4-Star General James T. Conway. The position holds 4-Star General rank, regardless of the officer's actual rank. For example, a 2 or 3 star General can be selected and confirmed by the Senate for that position, and thereby gains 4-Star rank by virtue of holding that position, but would revert to their former rank when they left. That's why most retire after serving (your pension is based on highest rank achieved), though not all do.
The highest rank is Tai Pan
