What three elements must be entered into the USMC Fitness Report?

The correct choice highlights the essential elements required for the USMC Fitness Report. In this context, height, weight, and body fat are critical measures reflecting an individual's physical readiness and overall fitness level.

Height and weight provide fundamental metrics for assessing an individual's physical stature and distribution. Body fat percentage is particularly important in the military to ensure personnel maintain a standard level of fitness and health. The combination of these three factors helps evaluate a service member's suitability for duty and readiness for physical challenges, aligning with the USMC's focus on maintaining high fitness standards.

Understanding this combination is important as it supports the overall aim of the USMC Fitness Report to promote and ensure physical fitness among service members. The other choices do not encompass the specific requirements listed in the USMC Fitness Report policy, focusing instead on metrics that are either not included or not primarily emphasized in the report.
