Second sergeant is typically a non-commissioned officer rank, used in many countries.
Second Sergeant is a specialist rank in the Singapore Armed Forces.
Third sergeants may be promoted to the rank of 'local second sergeant', holding this local rank only for the conscript period of their active national service, i.e. more responsibilities but without any extra NS allowance compensation.
After ORD, the local promotion will not carry over to conscripts' reservist cycle.
