Which order provides physical fitness requirements for the Marine Corps?

The correct answer is based on MCO 6100.3, which establishes the physical fitness requirements and standards for the Marine Corps. This order outlines not only the criteria that Marines must meet in order to pass physical fitness tests, but also addresses the importance of physical conditioning in maintaining readiness and overall health.

MCO 6100.3 provides details on the components of the physical fitness program, including testing procedures, frequency of assessments, and specific fitness standards that reflect the expectations for Marines across different ages and genders. By emphasizing structured physical training and the need to maintain a high level of physical readiness, this order supports the fundamental role that fitness plays in the mission readiness of Marine Corps personnel.

The other options, while they may pertain to fitness and readiness, do not specifically focus on the established physical fitness standards as outlined in MCO 6100.3. This distinction is critical for understanding which document serves as the primary authority for physical fitness requirements in the Marine Corps.
