“The Marine Corps’ style of warfare requires intelligent leaders with a penchant for boldness and initiative down to the lowest levels. Boldness is an essential moral trait in a leader for it generates combat power beyond the physical means at hand. Initiative, the willingness to act on one’s own judgment, is a prerequisite for boldness. These traits carried to excess can lead to rashness, but we must realize that errors by junior leaders stemming from overboldness are a necessary part of learning.” WarLearningMilitaryErrorsCommandInitiativeMarine CorpsUsmc Book:Warfighting Source: Warfighting
“There are two basic military functions: waging war and preparing for war. Any military activities that do not contribute to the conduct of a present war are justifiable only if they contribute to preparedness for a possible future one. Clearly, we cannot afford to separate conduct and preparation. They must be intimately related because failure in preparation leads to disaster on the battlefield.” WarTrainingPreparationMarine CorpsUsmc Book:Warfighting Source: Warfighting
