Marines is a 2025 American documentary series directed by Chelsea Yarnell, offering an unflinching look inside the 31st Marine Expeditionary Unit as they train for combat readiness across the Pacific region. The series brings rare, camera-access footage of one of the U.S. military's most elite rapid-response forces operating at the edge of their limits.

What is Marines about?

The 31st Marine Expeditionary Unit — a self-contained sea-based strike force permanently stationed in the Western Pacific — faces a relentless cycle of training designed to keep them battle-ready for any scenario. Each episode places viewers alongside marines during high-pressure exercises: amphibious assaults, jungle warfare drills, helicopter insertions, and coordination with allied naval forces across the Indo-Pacific. Veteran journalist Sebastian Junger and embedded participants Pryce Seymour and Rolan Smith provide ground-level perspective on what it means to serve in this uniquely demanding environment, where physical limits are tested daily and the line between exercise and real deployment stays razor-thin.
