Not a huge fan of this mission, simply because it's hard to see. You'll have to make your way towards the bank through all the dust and dirt. You won't have much to do until you enter an alley and you're told to come back into the tank so they can close the hatch. You'll take control of the tank at this point. Follow your tank buddy until he gets it. Head around the corner behind him and when you see the giant mound of debris, turn right and go through a store rather than over the mound. Push through and clear enemy infantry on the far side. Move up the street towards the bank and take out any tanks outside the bank. Keep heading towards the bank. Drive right up the steps and you'll get immobilized.
You'll be forced out onto the Machine Gun. From here, you'll have to fend off waves of enemies to provide cover for the marines in the bank. Just keep at it as long as you can. Eventually a chopper will arrive to pick up the marines. Keep shooting and shooting until the mission ends. Just make sure you keep an eye out for RPGs.
