After rounding the bend to a large city square, stop moving and start firing on the heavy armor in the square. Focus on the half-tracks first, then turn your attention to the Panzer tank.
Eventually, a third half-track arrives on the square. After it goes down, a squad of rocket launcher enemies appears in the building on the other side of the square. It’s best to remain back at the entrance road, as it’s easier to dodge the incoming rockets. Shell the building until no enemies remain. Now, patrol the plaza killing any stragglers. Once the all-clear signal is given from the soldiers, control switches back to Daniels’ perspective.

To earn this achievement, you must make it through this entire tank section without taking more than 20% damage. This is extremely difficult, so attempting this on Recruit difficulty should be considered. Using the “Last Checkpoint” trick mentioned previously is a good way to avoid having to restart the whole level if you fail.
