Leading Marines: Marine Corps Warfighting Publication MCWP 6-11

The most important responsibility in our Corps is leading Marines. If we expect Marines to lead and if we expect Marines to follow, we must provide the education of the heart and of the mind to win on the battlefield and in the barracks, in war and in peace. Traditionally, that education has taken many forms, often handed down from Marine to Marine, by word of mouth and by example.
