Non-commissioned officers {{#invoke:main|main}} A non-commissioned officer (NCO) is an enlisted member of the armed forces holding a position of some degree of authority who has (usually) obtained it by advancement from within the non-commissioned ranks. Officers who are non-commissioned usually receive management and leadership training, but their function is to serve as supervisors within their area of trade specialty. Senior NCOs serve as advisers and leaders from the duty section level to the highest levels of the armed forces establishment, while lower NCO grades are not yet considered management specialists. The duties of an NCO can vary greatly in scope, so that an NCO in one country may hold almost no authority, while others such as the United States and the United Kingdom consider their NCOs to be "the backbone of the military" due to carrying out the orders of those officers appointed over them.<ref>{{#invoke:citation/CS1|citation |CitationClass=citation }}</ref>

In most maritime forces (navies and coast guards), the NCO ranks are called petty officers and chief petty officers, while enlisted ranks prior to attaining NCO/petty officer status typically known as seaman, or some derivation thereof. In most traditional infantry, marine and air forces, the NCO ranks are known as sergeants and corporals, with non-NCO enlisted ranks referred to as privates and airmen.

However, some countries use the term commission to describe the promotion of enlisted soldiers. Especially in countries with mandatory service in the armed forces. These countries refer to their NCOs as professional soldiers, rather than as officers.
