Marine Corps Ranks

Every rank in the Marine Corps you achieve brings you closer to being the leader you were meant to be.

Start Tough. Then Build Your Legacy.

Many Paths, One Purpose. Earned Through Honor, Proven in Leadership.

No matter what role you serve in, every Marine contributes to a mission that’s larger than any single individual. From the newest Private to the most senior General, the rank structure of the Marine Corps reflects a clear path of growth, responsibility, and leadership. Across every specialty and assignment, Marines are united by a common standard and a shared commitment to excellence. As you rise through the ranks, your impact grows—not just in your field, but across the force.

As an enlisted Marine, you’ll begin your journey earning the title and living the values of the Marine Corps. From Private to Sergeant Major of the Marine Corps, the enlisted path is built on proven performance, discipline, and leadership. All enlisted ranks are characterized with an E for enlisted and a number showing their rank as an enlisted person. Within each pay grade, pay varies based on years of service and other factors. Promotions are based on merit and mission needs—earned through time in service, demonstrated skill, and the ability to lead.

Enlisted Ranks (E-1 to E-9):

  • E-1 to E-3: Entry-level Marines mastering core skills and discipline
  • E-4 to E-5: Noncommissioned Officers (NCOs) leading small teams and missions

E-6 to E-9: Staff NCOs and Senior Enlisted Advisors, managing operations and mentoring Marines across units

Enlisted Marines can attend specialized training, serve in elite roles, and compete for promotion boards to advance through the ranks of the Marine Corps. Many enlisted Marines also pursue commissioning programs to become officers.
