What's the job of a Second Lieutenant in the military?

I'm exploring ROTC and military options after high school, and I'm wondering about the role of a Second Lieutenant. What are their duties and responsibilities? How does this position fit into a military career?

A Second Lieutenant is the entry-level commissioned officer rank in the U.S. Army, U.S. Air Force, and U.S. Marine Corps. Traditionally, this position is one of leadership, with the primary duties being to lead and take care of enlisted service members within their unit.

In the Army and Marine Corps, Second Lieutenants often serve as platoon leaders, controlling a platoon of around 16 to 44 soldiers or marines. They are responsible for the well-being, training, discipline, and morale of the soldiers or marines under their command.

In the Air Force, Second Lieutenants may be tasked with a similar level of responsibility, or they might serve within a specific occupational specialty such as a pilot, navigator, specialist officer role (like intelligence or communications officer), or a support staff position.

As for how the position fits into a military career, it's usually the first step on the commissioned officer ladder. With experience and additional training, Second Lieutenants can be promoted to the rank of First Lieutenant, and can continue progressing up the ranks, each time gaining more responsibility and leadership roles.

However, requirements and experiences can vary greatly depending on the specific role, branch of service, and individual circumstances. Military careers can be varied, challenging, and rewarding, integrating not only operational duties but also continual leadership development, education and training. Your ROTC program will serve as a strong foundation for these responsibilities.
