Prototype

All vehicles count toward this. Civilian cars, APCs, tanks, and helicopters are all fair game. You will destroy plenty of vehicles throughout the story, but it will not be enough to unlock this trophy. The easiest way to rack up credit for this is to steal a tank or APC from the military, and just run over civilian vehicles. As long as you don't fire at any military vehicles or otherwise kill a lot of military personnel while they are watching, you will be free to crush vehicles without consequence.

You can track your progress under the Statistics -> Vehicles page on the pause menu.
