Security for corperations

I think that corps should have the option to defend themselves in case of a conflict by having a security option. A corp could employ security teams to guard there property and assets in case of war. They wouldn't be able to move and would only defend the Corp they are assigned to protect.

Maybe it's pointless with the real war battle, because any corp can't have a real weapon level power to defense itself, that's why the real world does the same.
I guess maybe you are a CEO want to build your army, but maybe this's not enterprise target.
Play as country, it's what I can suggest.

And this system hasn't design crimes system for every city and town.
But if it has...
WOW!
it'll be Amazing game to play.
