Complete the street section without Goliath taking any damage in Chapter 4: The Wall

---

There are eight RPG guys that are going to try and shoot the Goliath. Simply take these guys out before they can fire a shot. This can be done on any difficulty.

This starts at the "Goliath Returns" checkpoint and there may be a RPG KPA in the right corner. The achievement will pop right before the tank breaks through the wall.
