Partly to answer your first question, you need to have, and we always do have in fact, continuous planning for military missions. Every morning the commanding officers get up and have a meeting, an orders group, on what went on last night, how it's going, and how to adjust. That's all warfare stuff. They're always adjusting to the mission. If they say nothing happened last night, well, we'll stand down a few patrols.
It's important, and I think modern commanders understand that they have to play a part in the game of not escalating or unnecessarily de-escalating the impression of a threat.
What do you do when you're not in operations? The armed forces train. You simulate, you do exercises, you learn as much as you can.
Ladies and gentlemen, you have a very highly educated armed forces these days, and a very sophisticated training system.
The other thing you do, and what I would encourage, and I think most officers and others would agree, is you send as many people as you possibly can to all kinds of operations all over the place so that they can watch, see what's going on, learn something, and talk to their colleagues. That's the normal way of doing things.
