Cao Pi nods his agreement to both of them - what a good, healthy discussion. "There are things that can be set up officially," he acknowledges, "and other things we simply need to remind everyone to pick up as habit. For example, I admit that it isn't my habit to check in or make a report, if only because others always made their reports to me. So someone like me ought to learn the habit of picking up their tablet and reporting in."

Maybe by phrasing it as something he, too, would need to remember to do, he can convince others to do it. It is rather disturbingly telling that no one grabbed their tablet and put in a call on the network this last time - again - but they also had a pretty good read on where people were.

"Patrols are one thing and an organized sense of who is doing it when would not be bad. But the Commander has a fine idea: to have a plan that would only go into effect if someone called an alarm. Both the barricades, and the manpower, or whatever other form it takes."
