Under officer

The Royal Military College, Duntroon uses the appointments of senior under officer and under officer for senior Staff Cadets.[1]

In the Australian Army Cadets and Australian Air Force Cadets, the rank of Cadet Under Officer (abbreviated in writing to 'CUO') is the highest cadet rank. They are saluted and addressed as "Sir" or "Ma'am" by their subordinates but not by adult officers or instructors or members of the Australian Defence Force.

AAC cadet under officers may be assigned as national, regional, or battalion under officer, as quartermaster, or as the commander of a company or platoon. The rank badge is a lozenge, which contains 27½ chevrons. The national cadet under officer has red in the centre of the lozenge. Regional cadet under officers have blue in the centre of the lozenge.

To become a cadet under officer, a cadet must have completed the senior leaders course module two, otherwise known as the CUO/WO course, often held either at a mid or end of year session. The course runs for one week on a military base, and during this course a prospective cadet under officer will learn platoon and company level command. To gain entry to the course the cadet must have successfully completed the senior leaders course module one or the sergeant course, which entitles them to bear ranks up to staff sergeant.

To achieve the rank of cadet under officer, an AAFC cadet sergeant, cadet flight sergeant or cadet warrant officer must complete the cadet under officer course, which typically takes 3 weeks at a Royal Australian Air Force base in their home state. Upon successful completion of the cadet under officer course, cadet under officers are given full Officer privileges, which includes the right to use the officers' mess on military establishments.

The Indian National Cadet Corps appoints one senior under officer and three junior under officers in a company.[2] The Indian Military Academy and Officers Training Academy gentlemen cadets have similar appointments.

The Army Medical College has the appointments of "company senior under officer" and "company junior under officer" for senior cadets of each of the six companies, and two appointments of "battalion senior under officer" and "battalion junior under officer".

Under Officer is also a rank in the New Zealand Air Training Corps and the New Zealand Cadet Corps. In 2012 the rank was bought into the New Zealand Sea Cadet Corps, which replaced Master Cadet. It ranks between cadet warrant officer and ensign NZCF pilot officer NZCF or second lieutenant NZCF, thus making it the highest rank a cadet can reach, although not actually itself a cadet rank. Under officers are normally aged between 17 and 21, and to be eligible for a commission one must be at least 20 years of age. Under officers are cadets who have received the necessary training and have the desire to become NZCF officers. Hence, under officers are treated as understudy officers. There are 2 under officers' courses run each year, and provide the training that under officers require to be efficient understudy officers within their cadet units, and skills which will be useful as a commissioned officer. They perform roles similar to commissioned officers, but do not have nearly the same legal responsibilities and are not to be saluted, but are referred to as "Sir/Ma'am". Cadet under officers wear insignia similar to that worn by officer cadets, except that the thin blue braid is replaced by a piece of NCO chevron cloth. This emphasises their official status as cadets rather than adult leaders. The abbreviation for the rank of Under Officer is UO for all three corps.

To become an under officer, cadets are required to:

• Spend 6 months at the minimum rank of staff sergeant/flight sergeant
• Have completed at least 3 years of Cadet Forces training
• Have successfully completed SNCO course
• Be at least 17 years of age
• Have the desire, commitment & potential to become an NZCF officer
• Be recommended by their unit commander and have the approval of AC CFTSU.

Insignia worn by a Cadet Under Officer in the ACF

Under officer is an appointment held by senior officer cadets at the Royal Military Academy Sandhurst (RMAS) and in the University Officers Training Corps (although these latter are not strictly trainee officers), and is also the highest rank that can be held by cadets in the Combined Cadet Force and Army Cadet Force. There are two separate appointments: junior under officer (JUO) and senior under officer (SUO). They are usually addressed as "JUO" or "SUO" as appropriate, but are not saluted as they do not hold the Queen's commission. RMAS typically appoints two JUOs per platoon in the final term of the commissioning course. At RMAS and in the UOTCs, JUOs wear an Austrian knot above a single bar on their rank slide and SUOs wear an Austrian knot above two bars.

The use of the term in CCF contingents is inconsistent, with some having JUOs[3][4] and sometimes also SUOs,[5][6] and others simply having under officers.[7] The ACF has the single appointment of cadet under officer (CUO).[8] The rank badge is a white bar on the rank slide.[9][10]
