do you honestly think that the perimeter guards will be vunerable? I am thinking eye in sky and drones
How do the perimeter guards get to work? Do they live at their post, like robots? No.
I’m thinking cutting wheels and thermite on hundreds of thousands of miles of buried pipe and steel high tension towers.
Yeah, that can be guarded.
Yes.
Even the most competent professionals protecting the upper echelon are vulnerable to "shoot and scoot" attacks. They plan and train to react appropriately. But unless they have a quick-reaction force in reserve, the perpetrators may get away clean.
And there aren't enough competent professionals to cover everybody.
Lesser ranked members of the elites will have a minimal security screen. They won't have reserve forces in multiple rings around them. They won't have drones or access to the real-time surveillance feeds. They will have part-time coverage at their offices during the week days.
The second and third-tier officials will be reasonably safe from attack while their guards are on duty. Their guards won't be safe at all. They will be targets.
