You'll unlock the Quantum Aperture through completion of the Eurekabator! venture. This is basically a shield that allows you to see and shoot enemies through any surfaces for a limited time, including through tanks.

Once you've unlocked it, you'll need to equip it through the Skills App, it's the final skill listed. You'll then want to cause some trouble until you get max noteriety with the police, if you wait until you've unlocked the KAKTS Radio venture you'll have to max out noteriety for that anyway. Once you've maxed it out a tank should come after you, so activate the Quantum Aperature and shoot the outline of the tank driver for this trophy.
