Specialist

Specialist is the fourth progressive enlisted rank in the UNSC Army and is the highest non-NCO enlisted rank. Private's are usually promoted to Specialist after showing technical proficiency within a given field. It is equal in rank to Petty Officer Third Class in the UNSC Navy, Senior Airman in the UNSC Air Force, and Corporal in the UNSC Marine Corps and UNSC Army, to which they have equivalent pay. Specialists rank above Private First Classes, but rank under Sergeants; as such, Specialists are not considered Non-Commissioned Officers. The main difference between Specialists and Corporals is that Specialists provide technical leadership while Corporals provide command leadership. Specialists usually promote sideways to Corporal, but may be promoted directly to Sergeant.
