What is 1stsgt?

First Sergeant (1stSgt) is a senior non-commissioned officer rank in the Marine Corps, Army, and Air Force. They are typically a senior enlisted advisor to a company commander or higher-level officer, responsible for the administration and leadership of a unit of 100 to 250 Marines, Soldiers, or Airmen.

A 1stSgt is responsible for ensuring that their unit is trained and ready to carry out assigned missions, maintain discipline, and care for the welfare of the troops under their command. They serve as a role model for junior enlisted personnel, providing guidance and mentorship, and are typically the first point of contact for addressing issues or concerns within their unit.

To become a 1stSgt, a service member must have a minimum of 12 years of military service and have demonstrated leadership ability through multiple levels of promotion. They must also complete various leadership courses and pass written, physical, and leadership evaluations.
