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 combat exercises staged across the Pacific, where every drill is planned and judged as if it were the real thing. The series is credited to a team that includes veteran war reporter Sebastian Junger, with Pryce Seymour and Rolan Smith among those featured, and it keeps a 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.
About the cast
Director Chelsea Yarnell shapes this documentary with an observational approach that stays close to the unit and its daily routine. Sebastian Junger, known internationally for his war reporting and documentary work, is the best-known name credited on the series. Pryce Seymour and Rolan Smith are credited alongside him, and the series as a whole favours lived experience over institutional narration.
