What is a required component of the Combat Fitness Test?

The 880-meter run is a required component of the Combat Fitness Test (CFT). This distance assesses a Marine's stamina and cardiovascular endurance, which are crucial for the physical demands they may encounter in combat situations. The CFT is designed to evaluate a Marine's ability to perform in a combat environment, and running is a fundamental physical activity that significantly impacts overall performance and endurance in various operational scenarios.

In contrast, the other options do not align with the structure of the CFT. A written test does not gauge physical fitness, while focusing solely on strength training overlooks essential endurance and mobility aspects tested in the CFT. A team obstacle course, while useful for developing unit cohesion and tactical skills, is not a specific requirement of the CFT. Thus, the 880-meter run is integral to the holistic assessment of a Marine's combat readiness.
