The Art of Tetman Callis

“In war, the soldier is the instrument with which leaders must work. They must learn to play on his emotions—his loyalty, his courage, his vanity, his sense of humor, his esprit de corps, his weakness, his strength, his confidence, his trust. Although in the heat of battle there is no longer time to prepare soldiers for the violent impressions of war, there are, however, two simple means by which a leader may lessen tension: He can do something himself that will give the men a feeling of security; or he can order his men to do something that requires activity and attention.” – George C. Marshall, Infantry in Battle
