The Marine Corps has issued an administrative message asking for debate within the Corps on the most effective approach for preparing Marines physically and mentally for the demands of combat, with a particular focus on the military occupational functional requirements of each job. The message, MarAdmin 579/06, notes that the physical preparedness required for effectiveness in combat “rivals the requirements of professional athletes,” and concludes that current physical fitness training practices fail to take advantage of recent developments in athletic preparation in many sport disciplines. The goal, says the message, is to provide functional fitness exercises to “mimic the compound motions required for performance of physical tasks in combat” on a daily basis.
