It's also strange that you can sell it in a context of 'being prepared', with the offroad capability and everything - I don't know a better example for a vehicle being dependent on an always-on infrasructure than an armored electric truck.
Why? It is so, so much easier to produce your own electricity than your own gasoline. A truck running on slightly impure ethanol or gasified wood would still be more independent, but there are performance issues to consider there.
Why?
It seems to me people like the martial aesthetic and function(!) as a status symbol, maybe without reflecting why the martial aesthetic is what it is. To keep people in a metal shell with guns on it from being shredded.
A civil society should find these things ugly but respect their necessity, not celebrate them. And if civil society has a real need for these things, it's in a sad state.
Also, weapons and weaponry can be aesthetically pleasing without accepting the inevitability of violence.
