“When (a commander of infantry) engages the enemy not more than one quarter of his men will ever strike a real blow unless they are compelled by almost overpowering circumstances or unless all junior leaders constantly "ride herd" on troops with the specific mission of increasing their fire. The 25 percent estimate stands even for well-trained and cam-paign-seasoned troops. I mean that 75% per cent will not fire or will not persist in firing against the enemy and his works. These men may face the danger but they will not fight.” - SLA Marshall
