  the RPE scale—a Soldier’s estimate of how hard he or she is working. This training integrates into the
  Soldier’s ability to avoid fatigue, or arrive too soon at an objective.
  Physical Readiness
  Physical readiness is the ability to meet the physical demands of any duty or combat
  position, move lethally on the battlefield, accomplish the mission and continue to fight,
  win, and come home healthy.
  NUTRITIONAL READINESS
  3-6. Nutritional readiness has evolved over the past four decades from a series of disjointed ideas and one-
  size-fits-all guidelines into an evidence-based science promoting integrated and personalized practices.
  Whereas earlier efforts were based on static recommendations focused on the fuel needs for endurance sports,
  contemporary performance dietary guidelines are mission- and individual-driven and periodized to enhance
  readiness.
  3-7. The goal of nutritional readiness is to promote optimal performance readiness. For Soldiers to perform
  optimally throughout their careers in assignments with varying levels of mental and physical difficulty, they
  must place as much emphasis on nutrition programming to support that performance as they do on physical
  and mental health. Nutritional readiness intertwines with the other readiness domains since it promotes and
  is supported by optimal physical readiness, mental readiness, spiritual readiness, and sleep readiness.
  3-8. A comprehensive performance nutrition program is proactive, active, and reactive:
  * Proactive. Proactive nutrition provides the foundation for baseline health and homeostasis
  (physiological equilibrium)—the proactive prevention of nutrition deficiency, chronic disease and
  immune system compromise.
  * Active. Active nutrition fuels the arduous activities and events Soldiers perform as part of their
  occupations and covers fueling before during and after these events. It comprises the largest
  portion of this section.
  * Reactive. Reactive nutrition centers on specific dietary interventions to treat illness, injury, or
  medical conditions and spans hospitalization through rehabilitation to return to full duty.
  Nutritional Readiness
  Nutritional readiness is the ability to recognize, select, and consume the requisite food
  and drink to meet the physical and nonphysical demands of any duty or combat
  position, accomplish the mission and come home healthy.
  MENTAL READINESS
  3-9. Mental readiness is the capacity to adapt successfully in the presence of risk and adversity. It can be
  seen as a set of personality traits, an assortment of skills or ways of behaving and thinking, or a combination
  of both personality traits and behaviors. Whether Soldiers think of mental readiness as something they have
  (such as a personality trait or disposition), something they do (such as a plan, strategy, or way of behaving),
  or something they believe (such as a faith, positive outlook, or neutral outlook), it will help Soldiers better
  understand uncertain situations and will make them aware of their own mental processes.
  3-10. Under extreme duress, mental readiness is the ability to create a sense of total control and confidence.
  In the presence of chaos and uncertainty, possibility for flawed judgment increases. Mental readiness reduces
  miscalculation and errors of judgment. Soldiers who are mentally ready can manage severe stress and grow
  mentally tougher in the process.
