A "lieutenant" is a military rank that typically falls below a captain and above a second lieutenant. In many armed forces, lieutenants are responsible for leading small units, managing personnel, and executing orders from higher-ranking officers. They often serve as a bridge between enlisted personnel and higher command. In addition to the military, the term "lieutenant" is also used in various organizations, such as police departments and fire services. In these contexts, a lieutenant usually oversees a specific division or team, ensuring that operations run smoothly and that protocols are followed.
