The US military uses a rank system to denote experience, seniority, and responsibility. Ranks are typically earned based on combat achievements or special training received while enlisted. A gunnery sergeant is the seventh rank in the US marine corp. It is one rank above staff sergeant and one below master sergeant. The rank is represented by three gold bars; two crossed rifles sit in the middle of the second bar.
Coordinate Daily Training Regimens
Company gunnery sergeants coordinate daily training programs for the company. A company is roughly 120 marines. The gunnery sergeant prepares the marines in the company for combat operations and ensures that the marines remain in peak physical condition. The gunnery sergeant helps coordinate work out routines and combat training regimens. Gunnery sergeants act as mentors and leaders for other marines and provide the marines in their company with guidance, motivation, and instruction.
Act as Liaison
The gunnery sergeant is a company's liaison to the higher ranked military personnel (master sergeants, first sergeants, master gunnery sergeants, and sergeant majors). When higher ranking military personnel decide on operational or administrative manners, the gunnery sergeant must relay this information to the lower ranking marines in his company. Additionally, the gunnery sergeant must report any concerns or issues that develop in his company to higher ranking military officials.
Enforce Policy and Provide Aid and Resources
Company gunnery sergeants are responsible for enforcing rules and policies. They must ensure that the marines in the company follow protocol and maintain military decorum. This means the gunnery sergeants must ensure that uniforms are worn appropriately and that rooms are kept clean as well as enforcing other rules. Any reports required by the company (fitness reports, academic reports, or other types) must be submitted to the gunnery sergeant for review. The gunnery sergeant must supervise the physical health of the marines and ensure that the marines are properly instructed on matters involving personal fitness, health, and even financial decision making. The gunnery sergeant must contact appropriate agencies (such as health professionals) or provide resources to the marines individually so that they can get the help they need.
