Meaning
A senior non-commissioned officer rank in the United States military, typically serving as the principal enlisted advisor and manager of administrative, training, and disciplinary matters for a company, battery, or similar-sized unit.
A position of significant leadership and responsibility, often embodying the institutional knowledge and day-to-day operational authority within a unit. The role bridges the gap between commissioned officers and junior enlisted personnel.
Linguistics
Semantic Notes
Refers specifically to a military rank/position, not a descriptive phrase (e.g., 'the first sergeant to arrive'). Often used as a title of address ('First Sergeant Smith').
Dialectal Variation
British vs American Usage
Differences
The rank 'First Sergeant' is specific to the US military. The British Army equivalent in function and seniority is typically a 'Company Sergeant Major' (CSM) in the Army or a 'Flight Sergeant' in certain RAF contexts, though the exact rank structures differ.
Connotations
In US usage, it carries strong connotations of authority, experience, and unit leadership. In UK contexts, the term might be understood but is not a native rank title.
Frequency
Exclusively high-frequency within US military discourse. Virtually unused in general British English.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'первый сержант' as it is not a standard Russian military rank. The closer functional equivalent would be 'старшина роты' (company chief sergeant).
Common Mistakes
- Using it as a generic term for any senior sergeant (it's a specific rank).
- Confusing it with 'Sergeant First Class' (a different, often junior, rank).
- Omitting the word 'First' and thus referring to a different, lower rank.

FAQ
Frequently Asked Questions
No. A Sergeant Major (e.g., Command Sergeant Major) is a higher, more senior rank than a First Sergeant. A First Sergeant typically leads at the company level, while Sergeant Majors serve at battalion level and above.
Yes. In formal address, it is 'First Sergeant [Name]'. Informally, especially in the US Army, it is common to shorten it to 'First' or use the slang term 'First Shirt' when referring to the position.
Primarily the US Army and US Marine Corps. The US Air Force and US Space Force have the rank but with a different insignia and often a slightly different role focus. The US Navy's equivalent is a 'Chief Petty Officer' serving as a 'Chief of the Boat' or in a similar senior enlisted leadership role.
Both are senior NCO ranks. A First Sergeant (insignia: a diamond within the chevrons) holds a designated leadership position as the senior enlisted member of a unit. A Master Sergeant (insignia: chevrons only) is a technical expert and leader but not necessarily in the specific 'First Sergeant' duty position. A Master Sergeant can be promoted to the rank of First Sergeant.
