Second sergeant

Second Sergeant is a specialist rank in the Singapore Armed Forces. Second sergeants are more senior than third sergeants, but less senior than first sergeants. The rank insignia for a second sergeant features the three chevrons pointing down shared by all specialists, and one chevron pointing up.

In combat units, second sergeants often hold the appointment of platoon sergeant. They are often given instructional billets as well. Third sergeants may be promoted to the rank of 'local second sergeant', holding this rank for the term of their active service only. A local promotion will not carry over to conscripts' reservist periods.
