“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.”
