After you have followed the tanks, you will need to make your way into the building that has a blue item above it, once you are inside you will need to destroy everything that is located in side the building. Once you have done that, you will need to take out the enemies and the enemy tanks.
After you have taken out the tanks and the enemies, there will be one more tank that will appear, you will need to take this tank out too.
Once you have cleared the area, head towards the marker, once you have reached the marker you will need to protect the soldiers you can see in this location.
To protect them, you will need to look into the distance and take out the enemies. Once you have taken them out, there will be two more waves of enemies.
Once you have made it to the third wave of enemies you will be killed as it is really hard to see the enemies through the thick cloud of dust, you will then enter a cut-scene.
