The Republic of Korea Air Force's Officer Training School (OTS) is a popular and competitive officer training program in South Korea. ROKAF OTS trains the majority of its candidates for air defense forces and military police. While OTS also trains pilots, the majority of ROKAF pilots come from the Air Force Academy or ROKAF ROTC programs.

For the Royal Navy (RN), its IOT is undertaken at the Britannia Royal Naval College (Britannia RNC, or BRNC), also known as HMS Dartmouth (a stone frigate), at Dartmouth in Devon, whilst IOT for the Royal Marines (RM) is carried out at the Commando Training Centre Royal Marines (CTCRM). For Royal Air Force (RAF) IOT, that is undertaken the Royal Air Force College Cranwell (RAFC Cranwell, or RAFC), located within the RAF Cranwell airbase. In a similar vein to Sandhurst, Dartmouth and Cranwell also train future officers of many different foreign and Commonwealth militaries. The Royal Navy commissioning course at Dartmouth is 30 weeks, whilst the Royal Marines course lasts 15 months and is split between CTCRM and BRNC. Royal Air Force officer cadets undergo a 24 week course at RAFC.

Once graduated and commissioned, officers of all services may undertake further specialist post-graduate training appropriate to their military profession, such as flying training, engineering, logistics; and these will invariably multi-service training establishments. One example being

In the United States Armed Forces, Officer Candidate School (OCS) or the equivalent is a training program for college graduates and non-commissioned officers, soldiers, sailors, marines, airmen and coast guardsmen to earn commissions as officers. The courses generally last from six to seventeen weeks and include classroom instruction in military subjects, physical training, and leadership.

People may earn a commission in the United States Armed Forces through OCS or

  (2LT) and then attend the rest of their Basic Officer Leadership courses. In 2006, the officer commissioning programs changed, making the entire process, "Basic Officer Leadership Course", occurring in two phases (BOLC-A and BOLC-B). Phase A is the original commissioning source (OCS, ROTC, USMA, Direct). BOLC B is the Officer Basic Course which trains the new officers into their Basic Branch skills and includes three weeks of basic soldiering skills.

  NAS Pensacola, Florida. In the 1990s, OCS had departed Newport to combine with Aviation Officer Candidate School (AOCS) at Naval Air Station Pensacola. On its return, it brought the tradition of USMC drill instructors (a la An Officer and a Gentleman) from NAS Pensacola. Upon completion, graduates are commissioned in the rank of ensign
  (ENS) in the U.S. Navy.
• The
  USAF. It is a 9-week-long program consisting of two parts. In the first part, officer trainees learn military skills, USAF history, and other classroom and skill courses needed for serving in the Air Force. In the second part, they are given ranks from Officer Trainee O-1 (2d Lt) to Officer Trainee O-6 (Col), and learn how to be a leader, including the opportunity to lead other Officer Trainees. Graduates are commissioned as Second Lieutenants (2d Lt) in the U.S. Air Force. The second program is Commissioned Officer Training (COT), a five-week introductory program to the USAF for those who have been directly commissioned in the USAF, primarily as chaplains, doctors, and lawyers. Trainees in COT range in rank from O-1 to O-5 and will report directly to their respective units after training. The third program is the Academy of Military Science (AMS), a detachment of the Air National Guard Readiness Center that is embedded at OTS. AMS is a six-week program designed to train and commission officer candidates to fulfill USAF and Air National Guard
  (ANG) requirements. The AMS program covers the same subject areas as BOT and COT, but also provides education in ANG heritage and the role of the "Citizen Airman". The majority of AMS students are prior-enlisted and many may also have civilian careers. Once AMS candidates successfully complete all OTS graduation requirements, they receive the oath of office and receive state and federal commissions as second lieutenants in the ANG with both state and federal responsibilities.

  U.S. Coast Guard Academy in New London, Connecticut, where it has been located since August 1998. Prior to August 1998, Coast Guard OCS was located at the Coast Guard Reserve Training Center (RESTRACEN) in Yorktown, Virginia
  . OCS is a 17-week-long program, the longest of the 5 military services. Graduates are commissioned in the rank of ensign (ENS) in the U.S. Coast Guard and may report to Coast Guard cutters, sectors, or directly to flight training.
• SDF and National Guard counterparts) the curriculum is often similar, with the National Guard curriculum taking on additional requirements to meet federal recognition (referred to as FEDREC^[4]). For example, California maintains both Officer Candidate Schools at Camp San Luis Obispo, with the State Guard OCS being 11-12 months and the National Guard OCS being 16-18 months, both celebrate a joint graduation.^[5]
• During WWII, the U.S. Army Signal Corps ran an Officer Candidate School located in the war zone labeled as the South West Pacific Area (SWPA), at Camp Columbia, Brisbane, Australia. From photographs taken by the U.S. Army, it is apparent that this course was integrated with the U.S. Army's Signal Corps OCS program at Ft. Monmouth, New Jersey. Contemporary records indicate that the course was branch immaterial – perhaps the first branch immaterial course in the Army. Unfortunately, there is little information about the particulars of how SWPA OCS was operated, such as its length, subject matter content, training routine, etc. In particular, its years of operation and other reliable statistical information are not readily available.[6]
