In the Singapore Armed Forces, a platoon sergeant serves as the "bridge" between the platoon commander and the rest of the platoon, leading the platoon in many assigned tasks and assuming command in the platoon commander's absence. In some platoons, there may be more than one platoon sergeant.

Platoon sergeants exercise authority over section commanders who are only responsible for the management of a given section in the platoon. Platoon sergeants work with the Company Sergeant Major and subordinate section commanders. They are responsible for the discipline and training of the men. The platoon sergeant is responsible for preparing the men for parades and ceremonies. In exercises and operations, he is in charge of logistics, medical aid, and ensuring that the formation of the platoon is maintained during movement to a mission objective.
