Officer Cadet School (Singapore)

The Officer Cadet School (OCS, Chinese: 见习军官学府, Malay: Sekolah Pegawai Kadet, Tamil: பயிற்சி அதிகாரிப் பள்ளி) is a military training centre that trains commissioned officers for the four branches of the Singapore Armed Forces (SAF): the Army, the Navy, the Air Force, and the Digital and Intelligence Service.

Located within the SAFTI Military Institute complex in Jurong West, it has twelve wings inclusive of tri-service wings. Nine wings are named according to the NATO phonetic alphabet from A (Alpha) to E (Echo) and S (Sierra) and T (Tango), while the remaining three wings (Mids, Air and Dis) are for the Navy, Air Force, and Digital and Intelligence Service, respectively.

The trainees are mostly drawn from the best performing recruits in each basic military training cohort. Trainees with outstanding performance from the Specialist Cadet School (SCS), where specialists (non-commissioned officers) are trained, are also invited to transfer to OCS. Career soldiers may also attend OCS on application, recommendation and selection. OCS trainees are known as Officer Cadets (OCTs) if they serve in the Army and Air Force, Midshipmen (MIDs) if they serve in the Navy, and Senior Military Expert Trainees (ME4Ts) if they serve in the Digital and Intelligence Service.
