What are the responsibilities of officers in the military?

I've been considering becoming a military officer after high school, but I don't know much about what they actually do. Could someone provide some insights into the responsibilities of officers in each branch of the military?

Military officers carry key responsibilities across all branches of the military, though the specifics can vary. Generally speaking, they are responsible for planning, managing, maintaining standards, making vital decisions, and providing overall leadership for enlisted personnel.

In the Army, officers typically command a company sized unit (100-200 soldiers). Responsibilities often include training soldiers, ensuring they are ready for deployment, and leading them in combat operations if necessary.

In the Navy, officers often serve aboard ships or submarines and may hold technical roles such as navigators, or operational management positions where they oversee enlisted personnel. At a more senior level, a Navy officer may command an entire ship or submarine.

In the Air Force, officers may be pilots, navigators, or bombardiers. They are also present in technical roles relating to the management, maintenance, and operation of sophisticated technology used by the Air Force. Leadership roles see them managing aircrews and maintenance teams on a variety of aircraft and equipment.

Marine Corps officers command tactical combat units and are also involved in planning and coordinating operations, logistics, and support, given their role in amphibious warfare as well as other missions across the full spectrum of conflict.

In the Coast Guard, officers may command cutters (large boats or small ships), be responsible for maritime safety and law enforcement, or oversee search and rescue operations, making decisions that can greatly impact the lives of others.

The Space Force, being the newest military branch, has officer roles primarily tied to space-based operations. Space Force officers might be involved in space operations (like satellite communications and missile warning), command and control, or cybersecurity to protect U.S. and allied interests in space.

The roles and responsibilities of officers in each branch of the military are vast and varied, often aligning with specific areas of interest or expertise. It's important to research and understand the requirements and expectations of becoming an officer in the specific branch you're interested in, to ensure that it aligns with your personal goals and aspirations.
