Numbers
The proportion of officers varies greatly. Commissioned officers typically make up between an eighth and a fifth of modern armed forces personnel. In 2013, officers were the senior 17% of the British armed forces,
and the senior 13.7% of the French armed forces. In 2012, officers made up about 18% of the German armed forces, and about 17.2% of the United States armed forces.
Historically, however, armed forces have generally had much lower proportions of officers. During the First World War, fewer than 5% of British soldiers were officers (partly because World War One junior officers suffered high casualty rates). In the early twentieth century, the Spanish army had the highest proportion of officers of any European army, at 12.5%, which was at that time considered unreasonably high by many Spanish and foreign observers.
Within a nation's armed forces, armies (which are usually larger) tend to have a lower ''proportion'' of officers, but a higher ''total'' number of officers, while navies and air forces have higher ''proportions'' of officers, especially since military aircraft are flown by officers and naval ships and submarines are commanded by officers. For example, 13.9% of British Army personnel and 22.2% of the RAF personnel were officers in 2013, but the British Army had a larger total number of officers.

cadets and graduates during the same time period. Many of these individuals, at the time all male, resigned their inactive USAF commissions and also attended AOCS for follow-on naval flight training. AOCs were active duty personnel in pay grade E-5 (unless having previously held a higher Active Duty or Reserve enlisted grade in any of the U.S. armed forces) for the duration of their 14-week program. Upon graduation, they were commissioned as ensigns in the then-U.S. Naval Reserve

on active duty, with the option to augment their commissions to the Regular Navy after 4 to 6 years of commissioned service.
AOCS also included the embedded Aviation Reserve Officer Candidate (AVROC) and Naval Aviation Cadet (NAVCAD) programs. AVROC was composed of college students who would attend officer training in two segments similar to Marine Corps PLC, but would do so between their junior and senior year and again following college graduation, receiving their commission upon completion of the second segment. The NAVCAD program was in operation from 1935 through 1968 and again from 1986 through 1993. NAVCADs were enlisted or civilian personnel who had completed two years of college, but lacked bachelor's degrees. NAVCADs would complete the entire AOCS program, but would not be commissioned until completion of flight training and receiving their wings. After their initial operational tour, they could be assigned to a college or university full-time for no more than two years in order to complete their bachelor's degree. AVROC and NAVCAD were discontinued when AOCS was merged into OCS in the mid-1990s.
Similar to NAVCAD was the Marine Aviation Cadet (MarCad) program, created in July 1959 to access enlisted Marines and civilians with at least two years of college. Many, but not all, MarCads attended enlisted "boot camp" at Marine Corps Recruit Depot Parris Island

The MarCad program was closed to new applicants in 1967 and the last trainee graduated in 1968.

as an independent service in September 1947, it then became a source for USAF pilots and navigators. Cadets had to be between the ages of 19 and 25 and possess either at least two years of college/university level education or three years of a scientific or technical education. In its final iteration, cadets received the pay of enlisted pay grade E-5 and were required to complete all pre-commissioning training and flight training before receiving their wings as pilots or navigators and their commissions as 2nd lieutenants on active duty in the U.S. Air Force Reserve on the same day. Aviation cadets were later offered the opportunity to apply for a commission in the regular Air Force and attend a college or university to complete a 4-year degree. As the Air Force's AFROTC and OTS programs began to grow, and with the Air Force's desire for a 100% college-degreed officer corps, the Aviation Cadet program was slowly phased out. The last Aviation Cadet Pilot graduated in October 1961 and the last Aviation Cadet Navigators in 1965. By the 1990s, the last of these officers had retired from the active duty regular Air Force, the Air Force Reserve

Non-commissioned members rise from the lowest ranks in most nations. Education standards for non-commissioned members are typically lower than for officers (with the exception of specialized military and highly-technical trades; such as aircraft, weapons or electronics engineers). Enlisted members only receive leadership training after they are promoted to positions of responsibility, or as a prerequisite for such.

Warrant officers
In some branches of many armed forces, there exists a third grade of officer known as a warrant officer. In the armed forces of the United States, warrant officers are initially appointed by the Secretary of the service and then commissioned by the President of the United States upon promotion to chief warrant officer. In many other countries (as in the armed forces of the Commonwealth nations), warrant officers often fill the role of very senior non-commissioned officers.

Non-commissioned officers
A non-commissioned officer (NCO) is an enlisted
Enlisted may refer to:

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.
In most maritime forces (navies and coast guards), the NCO ranks are called petty officer
