Singapore
In the Singapore Armed Forces, potential servicemen training to be officers are known as officer cadets in the Army and Air Force, while those in the Navy are known as midshipmen. All officer cadets and midshipmen receive tri-service initial training in Officer Cadet School before being sent to the appropriate training schools. They return to Officer Cadet School for their commissioning parade.
Officer cadets and midshipmen wear one, two, or three white bars on their shoulderboards to denote their seniority. The graduating class of officer cadets wear peaked caps and berets depending on their vocations, and are accorded the privilege of being addressed "sir" by junior officer cadets. At this point, they are given more privileges and responsibilities commensurate with their seniority.
Officer cadets take turns to hold various administrative and exercise appointments. Administrative appointment-holders' shoulderboards have additional loops and whorls known as "fishes" in addition to their existing one, two or three bars. Exercise appointment-holders wear yellow rank insignia appropriate to the appointment of the officer cadet. For example, an exercise platoon commander will wear two bars of a lieutenant, and his exercise platoon sergeant will wear a brassard with first sergeant's chevrons.
