The military ruck march, otherwise known as a loaded march or forced foot march, is part of army training for different militaries all over the world. The ruck march is one course in a series of tests under U.S. Army regulations in order to earn the Expert Infantryman Badge (EIB). The EIB is a special skills badge awarded to recognize Infantrymen who have demonstrated a mastery of critical tasks, including the ruck march, physical fitness assessment, land navigation, weapons navigation, and other individual tasks.  The ruck march requires the candidate to complete a 12-mile march within 3 hours while carrying a rifle and 35 lb minimum load that add up to the Army ruck weight standards, for a total of up to 70 lbs.
