How tough is the secretary who photocopies and sends out the forms to order the new tires? Does she get the same bus home every night?
How tough is the guy who sells the radiator for it? Does he live in a nice home in the suburbs?
It’s vulnerable, very vulnerable indeed. You just have to find out where it’s weak spots are.
Except that takes planning guerrillas do not always have time for.
I don’t deny what you say. But there are more things to consider.
I think the main point is that you can't expect to attack the points that are reinforced the most and succeed.
The better questions are... how far will it go on an empty tank? Can it drive over that plywood covered hole you dug in the road last week? How long can the driver stay in there without supplies? How well does it run with the exhaust packed full of mud?
It's always the easy stuff, it's almost always right in front of your eyes, but as people, we tend to make things more complicated than they really are. The designers are no different. They created a "bomb-proof" vehicle, but it still has the most basic of weaknesses.
