Non-physical domains in H24 are readiness factors that influence performance without being the physical training itself. The four areas that make up these domains are nutritional readiness, spiritual readiness, mental readiness, and sleep readiness. Together, they cover fueling the body, purpose and beliefs, cognitive resilience and stress management, and adequate rest, all of which shape performance, recovery, and overall resilience. The other options leave out at least one of these essential areas, so they don’t represent the full set of non-physical domains.

The sustaining phase is about maintaining mastery of both physical capabilities and nonphysical readiness across the full range of soldier responsibilities: occupational tasks, duty positions, and the demands of combat. This means continuing to develop physical attributes like strength, endurance, mobility, speed, and power, while also strengthening nonphysical attributes such as mental resilience, decision-making under pressure, teamwork and communication, sleep discipline, nutrition, and stress management. When these aspects are integrated, a soldier can consistently perform required tasks, fulfill their role within a unit, and respond effectively in combat. Limiting focus to only one area—tasks, positions, or combat—misses other essential components of readiness and wouldn’t prepare someone to perform across all contexts.

Resilience in H2F comes from having strong social connections and ready access to behavioral health resources. When soldiers have dependable peers, leaders, family, and unit support, they can share coping strategies, receive encouragement, and get practical help during stress. This social network reduces isolation, helps maintain motivation, and speeds recovery after demanding events, keeping performance stable under pressure. Access to behavioral health resources adds professional support, offering evidence-based tools for sleep, stress management, and coping skills. Easy, stigma-free access means no delays in getting help, which prevents problems from escalating and keeps resilience intact over time. Together, these elements create a framework that helps individuals adapt to stress, recover quickly, and stay mission-ready. Choosing isolation and avoidance cuts off those protective networks, undermining resilience. Ignoring mental health and relying on stimulants like caffeine without adequate rest disrupt recovery and can increase risk of burnout. These dynamics hinder the ability to cope with stress and perform consistently. So, social support and access to behavioral health resources best support resilience in H2F.

SPRC stands for Soldier Performance Readiness Center. The emphasis is on readiness that comes from optimizing how a Soldier performs across real-world tasks, not just building raw physical capacity. The term “Performance” conveys an integrated approach that covers movement quality, endurance, strength, task-specific skills, recovery, and the mental and cognitive aspects that affect performance under stress. A center with this focus acts as a hub for assessments, training, and recovery strategies—data-driven and tailored to individual soldiers—so they stay ready for whatever missions require. Choosing “Performance” rather than “Physical” signals this broader, more holistic view of readiness. The other options would imply a narrower scope (a focus only on physical fitness), a planning/program aspect, or a resources center, none of which captures the integrated performance-readiness mission.
