Officer (armed forces)

An officer is a member of an armed force or in some cases uniformed service who holds a position of authority. Commissioned officers derive authority directly from a sovereign power and, as such, hold a commission charging them with the duties and responsibilities of a specific office or position. Commissioned officers are typically the only persons, in a military environment, able to act as the commanding officer (according to the most technical definition of the word) of a military unit.[1] A superior officer is an officer with a higher rank than another officer.

Non-commissioned officers (NCOs) in positions of authority can be said to have control or charge rather than command per se, although the use of the word "command" to describe any use of authority is widespread and often official.

Having officers is one requirement for combatant status under the laws of war, though these officers need not have obtained an official commission or warrant. In such case, those persons holding offices of responsibility within the organization are deemed to be the officers, and the presence of these officers connotes a level of organization sufficient to designate a group as being combatant.
