How would you like to handle the logistics of that operation. You'd be one of many who was supposed to know what was going on but wouldn't have much of a clue. It's amazing that that succeded. Good people behind our troops there. Wish my grandpa was still around, we're losing our WWII vets fast and a ton of stories about grit and determination with them.
On that scale is easy. You give your subordinates instructions on what you want accomplished and get out of their way. Each person is responsible for his/her job and together you can accomplish nearly anything.
