What is the role of the First Sergeant (1SG)?

• A. Senior enlisted advisor to the Commander at the Company / Troop / Battery level; role model for all Soldiers, NCOs and Officers
• B. Commander of a company
• C. Platoon leader
• D. Senior administrator at battalion level

Answer: (A)

The First Sergeant is the senior enlisted advisor at the company, troop, or battery level, serving as the primary link between soldiers and the officer leadership. This role centers on guiding and mentoring the entire enlisted force, ensuring readiness, discipline, welfare, and standards across the unit. The 1SG works closely with the company commander to plan and execute training, supervise first-line supervisors, and maintain accountability for people and resources. They model professional appearance and conduct, set the tone for unit culture, and help soldiers with career development and counseling. In short, the 1SG is the go-to senior NCO for everything enlisted within the company, ensuring policies and programs are carried out and that the unit operates smoothly.

That’s why this choice fits best: the senior enlisted advisor to the Commander at the Company/Troop/Battery level, and a role model for all Soldiers, NCOs, and Officers. The other options describe roles at different levels or different positions (a company commander is an officer who leads the company, a platoon leader is typically a junior officer, and battalion-level administration is a higher-level or different role).
