“The load that Soldiers carry is an important planning consideration. How much Soldiers carry, how far, and in what configuration are critical mission considerations requiring command emphasis and inspection. Historical experience and research show that Soldiers can carry 30 percent of their body weight and retain much of their agility, stamina, alertness, and mobility.” – Combined Arms Doctrine Directorate, U.S. Army Combined Arms Center, ADP 3-90, Offense and Defense
