In the Singapore Armed Forces (SAF), specialists are the group of ranks equivalent to non-commissioned officers in other armed forces. This term was introduced in 1993, for a more "positive" rank classification and shorter waiting time for WOSPEC career soldiers' rank advancements. In the SAF, warrant officers are not considered specialists. The following ranks are specialist ranks: * Specialist cadet (SCT) * Third sergeant (3SG) * Second sergeant (2SG) * First sergeant (1SG) * Staff sergeant (SSG) * Master sergeant (MSG)
