Once you have control of the tank, move forward at full speed. You'll have to clear some tanks and you want to clear all six of them quickly for a chievo/ trophy. Just make sure you keep moving and firing at them. Lead them a little bit if you have to and definitely make sure your shots count because the reload time is rather long. Once they are clear, you may have to wait for the next phase of the mission to begin before you can advance, otherwise you will be told to return to the mission area.
You'll have to scope the next area out from above and paint some targets but it won't be successful. Instead, you'll return to your tank and advance toward the target. You'll be attacked a by a few tanks as you approach (you'll be given orange targets for them). Clear them and proceed into the base. Once inside, move your tank to the right side and then into the back of the base to get rid of the trucks here. You'll be told there is a second objective so move through the back of the base and continue on.
Eventually you'll be told there are tanks ahead. Once you get closer so you can eliminate them, you'll be flanked (to the left) by four more tanks. Get rid of all of these but remember to keep moving as best as you can. Once they are gone, approach the road beyond and destroy the convoy. After the trucks are destroyed, you'll have to sweep the area with your machine gun to get rid of any remaining infantry. They can't harm you so just move up the middle and around the outside of the convoy to clear it out.
Head out on the highway and you'll get to a bridge. You'll find Engineers under the bridge who are supposed to be clearing mines. They'll want you to do it for them so wait for your tanks to move up and sprint up the highway, using cover when you can so that you can collect the detonator. Head back to the engineers and you'll be prompted to detonate it. Do so and then jump back into the MG of your tank. You'll move up a highway and have to clear enemies to your right and in between the two strips of road. Clear them out and you'll keep moving. Watch for enemies scattered around rooftops with RPGs and cars/trucks that are moving because they'll be packing explosives.
Once you come to another bridge, you'll be attacked by a car. It will shoot past you and into another tank. I've never managed to stop it. After that, you'll be attacked by multiple vehicles. You need to take them out before they reach you. After this, you'll head into the city for the next mission.
