I spent a career carrying typically either an M16 or an M4 Carbine. An M4 Carbine fires a .223 caliber round, which is 5.56 mm at about 3000 feet per second.

Throughout my career, I have lived by the principles of personal honor and professional integrity.

Anyone in a position of power is either corrupt or assumed to be corrupt, and the assumption of corruption is as bad as the reality of it.

Over my career, I'd watched senior leader visits have unintended negative consequences. Typically, schedules were unrealistically overloaded and were modified during the visit to cancel parts of the plan.

When I was a lieutenant in Special Forces many many years ago, I thought I was getting fat. And I started running, and I started running distance, which I enjoyed.

A fundamental principle that I learned in my career, and a principle that my consulting company McChrystal Group helps American civilian companies to adopt, is that winning units and organizations ensure that the time they actually spend - daily, weekly, and yearly - must hew closely to their priorities.
