2LT

2LT, short for Second Lieutenant, is the entry-level commissioned officer rank used by several armed forces, including the United States Army and Air Force. It is designated as pay grade O-1 and is the first rank in the commissioned officer corps after graduation from an officer commissioning program (such as a service academy, ROTC, or officer candidate school).

Insignia: The insignia for a 2LT is a single gold bar worn on the uniform, with variation by service in placement and backing.

Role and responsibilities: A 2LT typically serves as a platoon leader or junior staff officer, responsible for leading and mentoring a platoon of enlisted personnel and, in some branches, for administrative tasks and mission planning under supervision of more senior officers. Duties vary by branch, specialty, and unit type (infantry, aviation, engineers, services).

Promotion and progression: Advancement to 1LT (First Lieutenant) generally occurs after a period of service and satisfactory performance, followed by promotion to Captain (O-3). Officers continue to develop leadership and professional competencies through courses and assignments, with progression shaped by branch requirements, performance, and time in grade.
