Military rank
A position in a military hierarchy that indicates a service member’s authority, responsibilities, and place in the chain of command.
Chain of command: The ordered structure through which authority and orders pass in an organization. Rank establishes positions within this line of authority.
Command responsibility: The accountability borne by a leader for a unit’s actions, decisions, and readiness. Rank can enable command, while responsibility attaches to the command actually held.
Military insignia: Symbols worn on uniforms to identify military rank, branch, qualification, or unit. Insignia display rank but are not the rank itself.
United States military rank: The rank structures and titles used across the United States Armed Forces. It illustrates how one national system organizes enlisted members and officers.
Commissioned officer: A military officer appointed by a state to command, lead, or serve in professional roles. Commissioned officers occupy one major category of military rank.
Military protocol: Formal rules governing military conduct, ceremony, and interaction among personnel. Protocols such as salutes often express recognition of rank.
Military seniority: Relative precedence among service members, often determined by rank and time in service. Two members of equal rank may differ in seniority and precedence.
British Armed Forces ranks: The rank titles and hierarchies used by the United Kingdom’s armed services. British ranks show how titles and precedence vary between national systems.
Non-commissioned officer: An enlisted service member promoted to a leadership role without receiving a commission. Non-commissioned officers lead enlisted personnel within rank structures.
Military promotion: The formal advancement of a service member to a higher military rank. Promotion changes a member’s standing and may expand authority.
