FM 7-22 provides guidance on which of the following?

FM 7-22 focuses specifically on holistic health and fitness, which is a comprehensive approach to physical training, health, and well-being within the U.S. Army. This field manual outlines the importance of a balanced regimen that includes physical fitness, nutrition, sleep, and mental resilience. Emphasizing a holistic view helps soldiers maintain optimal health, which in turn supports their performance and readiness for military duties. It highlights strategies for physical conditioning, healthy lifestyles, and the integration of mental and emotional aspects of fitness, which are critical for addressing the complex demands of military life.

While other options might address relevant topics within military operations and soldier welfare, they do not fall within the specific guidance provided by FM 7-22. This manual does not cover training and leader development in depth, nor does it focus on incident reporting or military justice, which are addressed in other FM publications. Therefore, the emphasis on holistic health and fitness makes this the correct choice.
