Untutored courage is useless in the face of educated bullets.

The line contrasts raw bravery with the modern, systematized lethality of warfare. “Untutored courage” suggests valor unaccompanied by training, doctrine, or tactical intelligence; “educated bullets” personifies firepower that is made effective by instruction—marksmanship, gunnery tables, coordinated fields of fire, and disciplined units. The implication is that courage remains necessary but is not sufficient: in industrial war, survival and victory depend on preparation, professional competence, and the ability to apply technology and organization. Read this way, the quote functions as an argument for rigorous training and leadership that converts individual spirit into effective combat power.
