Ranks and insignia of marine forces

Commissioned officers' and enlisted rank comparison chart of all marine forces.

The first warrant officer rank, WO1 does not have a "commission" associated with it, instead having a "Warrant" from the Secretary of the Army.

Warrant officers are allowed the same courtesies as a commissioned officer, but may have some restrictions on their duties that are reserved for commissioned officers.

Warrant officers usually receive a commission once they are promoted to Chief Warrant Officer 2 (CW2), but are usually not referred to as "commissioned officers".

WO1s may be and sometimes are appointed by commission as stated in title 10USC.
