Corporal
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.

Lee Harvey was in the Marines, they have 3 rankings for rifle qualifications, from lowest to highest: Marksman, Sharpshooter & Expert. Most Marines have to qualify with their rifle every 2 years. Oswald first earned a Sharpshooter (2nd highest) in 1957. When he qualified again in 1959, he earned Marksman (3rd highest rank). He never earned Expert.
Corporal. Note: An E3 in the Marine Corps is called a lance corporal; a rank which to the best of my knowledge only exists in the British Army and the US Marines. A lance corporal is the highest enlisted rank, and a corporal is the lowest non-commissioned officer rank.
It depends of what rank you are.
