I'll post the update in IC, butto summarise, changes.
the truck will be placed behind the corner (hidden from view and car node also hidden)
the gauss will be mounted on the doberman drone (node hidden)
I'll be by the truck (few meters from the drone) hidden, jacked into the drone.
We need to be in open (on the berm (whatever it is - I assume it is a pile of dirt)), daring the world without care for anything, because they won't attack us otherwise.
After few shots (at the airpoirt, tower, then at the car), I'll unmount the gauss. slow if possible (depending on the time barghest will need to run 1 km), bruteforce otherwise.
