Since Captain Samuel Nicholas was the first commissioned officer from 5 November 1775 until other officers were commissioned the oldest rank would have to be the rank of Captain. He was advanced to the rank of Major on 25 June 1776 and remained in Philadelphia until the war ended.
Enlisted - Sergeant Major of the Marine Corps . Officer - Commandant of the Marine Corps .
It varies depending on the rank. The table linked below has the information.
the lesser known E9 rank is Sergeant Major of the Marine Corps.
Since Samuel Nicholas was appointed a Captain of the Continental Marines five days before he began recruiting the balance of the Corps, it stands to reason that he was the only Marine for five days. Because he was commissioned as a Captain, the oldest rank by at least those five days was that of Captain.
The Commandant of the Marine Corps (CMC) : four star General James F. Amos .
Actually, a grade 5 private is Marine lingo for someone who countinually loses rank.
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.
The highest ranking officer of the US Marine Corps is Commandant of the Marine Corps Paygrade O-10.
Sergeant Major of the Marine Corps - there's only one in the entire Marine Corps.
The Marine Corps is a department of the Navy, but there are alot of differences. One for example is the ranks. Our ranks go from Pvt.-Sgt Maj. Theirs is Seaman- Cheif Petty officer. Also their officer ranks are different, OUr captain rank is their Lt. rank, our Col. rank is their Cpatain rank. Another difference is the Navy is mainly sea and somethimes air, and the Marine Corps can do things in the air, on land and sea. Also the Marine Corps is known for their first to fight. The Navy doesn't do that. The Marine Corps is also the Few, the Proud, the Marines. Semper FI!!
The 3rd rank achieved by an enlisted Marine in the US Marine Corps is the rank of Lance Corporal (LCpl). This rank is typically attained after serving for a specific period of time and meeting certain qualifications and requirements set by the Marine Corps.
