Brain-on-brain warfare; you need to read...think.write.

In the end, the quintessential skill of an officer is about bringing order out of chaos. To do that, you have to be calm, and smart, and willing to do the brain work. Because in the end, 21st Century security is about brain-on-brain warfare. We will succeed not because we have more resources, or because our values are the best, or because we have the best demographics or geographic advantages—all of those things matter, of course. But in today’s turbulent 21st Century, we’ll succeed and defeat our enemies by out-thinking them. To do that, and to be successful senior officers, you need to read … think … and write.
