Just Cause 3 - This was Supposed to be a Western Trophy / Achievement Guide - Destroy all Chaos Objects in a Base without leaving your vehicle. [Bronze / 20G]
This doesn't work in Outposts, Towns or Villages. It has to be a Military Base! You can reset every base after the final story mission.
The easiest location is the Military Base "Cima Leon: Silo" in the Lacos Province of Insula Fonte. There's a tank at the back of the base. Get in the tank and destroy all Chaos Objects in the base. Chaos Objects are the ones displayed in the bar on the left side (you don't need to destroy small explosive barrels, only the stuff that is required to conquer the base).
Make sure you do it with a tank. Don't use a helicopter, it will only get shot down. If you have already captured this base, either start a new game and go there right away or reset if after the final story mission.
