This sounds like such a bad idea, what if one of your employees has a concealed carry permit and chooses to defend themselves?

I think GP meant "tell employees that there's going to be a drill with men carrying fake weapons, act as if you were too terrified to defend yourself".

Er, definitely no fake weapons either, that seems like a massive unneeded risk and stress factor. Tell them that there is a drill and they're supposed to work with the red team to the same extent that someone might if being coerced with guns. They're not actually on the red team since they aren't working as trusted team members, but they are also helping the red team/not working against them. It's more like they're part of the environment and their job is to help run the simulation.

The adversary for the red team is the rest of the company that isn't being occupied, not the office that they did "occupy".
