General Ulysses S. Grant, who knew a thing or two about war, had criteria for leaders, which boiled down to humility; toughness of character, so one is able to take shocks in stride; and the single-mindedness to remain unyielding when all is flying apart but enough mental agility to adapt when their approach is not working. This was how I pictured my Marines fighting. In doing so, they would present the enemy with a cascading series of disasters, shattering his coherence and creating a state of confusion and an inability to concentrate his mind or his forces.
