Follow the trail until you encounter some hostile forces. Clear the initial group of enemies then proceed along the large, open path while taking out the enemies along the way. Be careful of the cartel thugs attacking from the rooftops. Follow Cordova to the alley next.
Head to the next street again and engage more enemies. Move up the street and hold out until more enemy reinforcements arrive. There's a wall to the left that will be blown open so enter it and go upstairs. Repel another enemy attack then push the ramp ahead for a scene.
Proceed to the next rooftop and kill the last brute inside the building. Follow the path to end the section.
