Watch things unfold and when you are told to find Price, look just above the clock for a glint of light. He will repel down the side and after a minute, you'll be instructed to take out the guards. Just keep knocking them down and Price will breach the room. Inside will be more guards so keep providing cover.
Once you gain control of your feet, start running after Price. Don't stop, just keep running until you set down for a moment and Price gives you his weapon. Now you shoot. Try and keep to the left side and move slowly, clearing one room at a time.
You'll come to a point where a few black SUVs will pull up. Try to drop grenade under them to get rid of some of the enemies coming out. Head through the building to the left and back out across the street. When they finally put Soap down again, you'll have to hold off the enemy until the resistance shows up to help. Go inside and tend to Soap, then leave.
