William McRaven: This is kind of what we did in Afghanistan. We normally had anywhere from ten to 15 missions a night in Afghanistan where you had Army Rangers or Navy SEALs or other Army Special Operations forces out conducting raids on Taliban targets with the same approach.  Helicopters going from a forward operating base to an objective, taking care of business on the target, getting back on the helicopters and coming back. So one, we didn’t want to change what we were doing for fear that people would know. So when we got to Afghanistan, my force had no clue that I had a separate force that was preparing to go conduct the raid, because we didn’t stop them from anything else that was going on that night.
