In many militaries, a platoon sergeant is the senior enlisted member of a platoon, who advises and supports the platoon's commanding officer in leading the unit. Singapore 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. For NSF soldiers (conscripts), platoon sergeants are selected as third sergeants. They are usually specialists who graduated with a Silver/Gold Bayonet whilst at the Specialist Cadet School, though it may not often be the case. NSFs who are in active units and who have shown exemplary conduct on and off the field can be recommended to attend the course and take up a NSF Platoon Sergeant Role. On completion of the platoon sergeant course at the Specialist and Warrant Officer Advanced School, they will assume their appointments. Promotion to the rank of 2SG will be determined by the parent unit. NSF platoon sergeants do not normally attain the rank of First Sergeant (1SG) before their national service period has concluded, although they may go on to achieve this rank during their annual reservist cycles. For Regulars, they are usually first sergeants. It is a must to have completed their section commander tour before assuming the appointment. United States U.S. Army In the United States Army, a platoon sergeant is usually a sergeant first class (E-7) and is the senior enlisted member of the platoon. From 1929 until 1942 (replaced by technical sergeant) and again from 1958 until 1988 (merged with sergeant first class), the separate rank title of platoon sergeant existed (abbreviated PSGT or PSgt.). The platoon sergeant is the primary assistant and advisor to the platoon leader (and acts as the platoon leader in his or her absence). Unless
