What military jobs are combat-heavy?

I'm considering a military path with a focus on combat. Which military jobs are known for their combat-heavy roles or involve being in the front lines the most?

If you're looking for jobs which are known for being combat-heavy or often involve front-line action, there are several roles across multiple branches of the military you might consider. Note that all these roles come with significant risks and require intensive training, so they're meant for individuals ready to face intense physical and mental challenges.

1. Infantry: Both the Army and Marine Corps have infantry roles which are combat-focused. Infantrymen often represent the main combat force in any military, and their role frequently involves engaging directly with enemy combatants.

2. Army Ranger: This is a highly trained and specialized combat role within the U.S. Army. Rangers are often sent on particularly challenging and high-risk missions.

3. Special Operations: Several branches of the military have their own special operations forces that often see combat action. This includes the Army's Green Berets, the Navy SEALs, and the Marine Raiders.

4. Combat Engineers: These professionals have a unique blend of combat and technical skills. Their tasks can range from constructing field fortifications to clearing obstacles during combat operations.

5. Pararescue: In the Air Force, Pararescuemen (also known as PJs) are trained to rescue and medically treat downed military personnel in all conditions, including active combat zones.

6. Cavalry Scout: Within the Army, the job of a Cavalry Scout is to gather critical information about enemy forces and territories. These positions can often find themselves facing direct combat.

7. Forward Observer: This role, which exists in the Army and Marine Corps, is responsible for directing artillery and other long-range weapons to enemy targets, often from frontline positions.

Remember that specific combat roles and their availability can vary depending on the exact branch of the military and the current operational needs. If you choose to pursue a military career, always consider multiple factors including the risks involved, future career prospects, and your personal interest and aptitude for the role. It is also advised to talk with a military recruiter to gain a comprehensive insight into what each role entails.
