Once you gain control, stick to the left side and stay behind cover whenever possible. Cross over with the armor until they ask you to scout up ahead so they know if it's ok to advance. Then you'll need to cross to the right side. Do so and follow the street to the end. The street will turn left into a group of enemies. They aren't anything you can't handle without patient use of cover.
The road will curve back around and do a U-turn to the left. Cross the street on the right side and take cover behind the potted plants in the area. Advance cautiously up the right side until you get to a truck you have to go around. Get around it and then get back on the right side. Slowly make your way to the large open area at the end of the road. Just be careful not to spend too much time in the middle of the road, lest you get run over by your own tank.
When you are just about to the open area, there is a hole in the wall on the right that will allow you to drop down and provides much better cover and angles. Keep following along with the wall to your right until you get to the west side and a group of enemies will pour out of a building just south of you. Keep shooting and you'll make short work of them. Follow the wall along and you'll come to some barbed wire. You'll then be told to get into the tank's turret.
Climb in and start shooting. Eventually the tank will have to back off but when you get a second chance, open up on the area to the right. The tank will hop the barrier and head into the parking garage. The tank will keep to the right-side. Clear the RPG to the left and then head forward. You'll pass a wall at some point where there are plenty of enemies beyond. Shoot the cars near them to clear them out quickly. If you aren't quick enough, you'll die pretty fast. Once you clear them though, it's smooth sailing until you fall through the ground for the third time in six missions.
Back to the infantry game. Exit the vehicle and follow the squad, sticking tone side or the other until you get to the jeep. Clear the area and climb blackout of the garage and into the streets. Make your way around the corner ahead and then head into another building. Make your way slowly along the right wall and watch left because you'll hit a point when you think you've cleared every enemy and he'll still jump out and melee you if you aren't paying attention. Soon the building leads back to the street.
Outside, you'll find a section that reminds me of Rainbow Six Vegas. I found the left side was easiest side to take cover in. Move up the left side and then turn right to thin out the enemy. Once you're through this section, move into the next section of street. Kill the enemies here and head into another building. Go up the stairs and breach the next room. Clear the room and you'll rescue the Goalpost.
