Book excerpt: Physical fitness and performance measures are predictive of Special Forces Assessment and Selection and performance during combat-specific tasks. In combat, approximately 50% of casualties are lost to direct-fire engagements, which requires resiliency to fatigue during repeated high-intensity sprints (under combat load) and delivering suppressive fire while under duress. Currently, the US Army does not have a physical fitness test that is predictive of combat survival. This study examined the predictive ability of field-expedient physical fitness/performance tests on a simulated military task (SMT) that mimicked a direct-fire engagement. Healthy subjects (N = 39, age = 25.3 ± 6.8 years) completed upper- and lower-body strength (i.e., handgrip, isometric midthigh clean pull) and power (i.e., seated power throw, standing broad jump) tests and a 3-minute all-out running test to determine critical velocity. Subjects returned to the laboratory to complete a simulated military task (SMT) that consisted of marksmanship with cognitive workload assessment (CWL) and a fire-and-move simulation (16 6-m bounds) while wearing a vest simulating a combat load (25-kg). Susceptibility to enemy fire was modeled on bound duration during the fire-and-move simulation. Stepwise linear regression identified predictors for the tactical combat movement simulation components. Significant regression models were identified for both susceptibility to enemy fire (R2 = 0.755, p 0.001) and cognitive performance (R2 = 0.162, p
