It is a full revision and expansion on physical readiness training doctrine. FM 7-22 presents individualized training and testing that builds peak performance in all Soldiers. It is the foundation of unit readiness. In an era of multi-domain operations all Soldiers must be able to fight and win in both defensive and offensive operations that occur without notice.
