Junior officer


Fitter, company officer or company grade officer refers to the lowest operational commissioned officer category of ranks in a military or paramilitary organization, ranking above non-commissioned officers and below senior officers.

The terms company officer or company-grade officer are used more in the Army, Air Force, or Marine Corps as the ranks of captain, lieutenant grades and other subaltern ranks originated from the officers in command of a company or equivalent (cavalry squadron/troop and artillery battery).[1][2][3][4]

In many armed forces, a junior officer is specifically a commissioned officer holding rank equivalent to a naval lieutenant, an army captain or a flight lieutenant or below.

In the United States Armed Forces, the term junior officer is used by the Navy and the Coast Guard for officers in the ranks of Chief Warrant Officer (W-2 to W-4), Ensign (O-1), Lieutenant, Junior Grade (O-2), Lieutenant (O-3), and Lieutenant Commander (O-4). Some people mistakenly believe that Lieutenant Commander (O-4) is not included in the junior officer category as per OPNAVINST 1650.33A.[further explanation needed]
