What is a second lieutenant (2Lt)?

A 2Lt, or Second Lieutenant, is the entry-level commissioned officer rank in many military organizations, such as the U.S. Army, Air Force, and Marine Corps. 2Lts are typically responsible for leading small units, such as platoons, and managing junior enlisted personnel. They receive training in leadership, tactics, and administration, and serve as the link between enlisted soldiers and higher-ranking officers. The 2Lt rank is an important starting point for a military officer's career, often requiring adaptability, strong decision-making, and effective communication skills.
