You can enter with your men and shoot everyone in sight, however it's easier to eliminate the capo with a sniper rifle . Find your target and shoot him from a distance .
Go back to Florida. Paul Morales  can be found under a flyover - drive there from the left side. .
Don't shoot the target, your bruisers has to kill him. Eliminate all the enemies . Leave only a man with the bruiser speciality in our team, send the others somewhere else. Finally approach Morales, quickly run to him and grab him. When your man will appear nearby, let him go and let the bruiser take care of him . After killing him, join up with the others.
Johnny Salazar , the last capo left alive, is on the roof of a multilevel car park - go there .
At the rear of the ground floor you can find some Molotov Cocktails (they're behind a fence; your engineer will cut through it easily). Drive your car to the highest floor accessible by a vehicle  and get out of the car. You can replenish your weapons by the boxes. Get higher while eliminating every single enemy .
Wait for Salazar to come down to you, or go to the top floor yourself. Whichever option you choose, throw a Molotov cocktail at your target . Once he's on the ground, throw another one .
Stanley Jimenez, Granados underboss, has to be strangled . Drive to his favourite place with your team .
Let the engineer cut the fence  and get rid of the guards together with your soldiers .
Look for your objective inside the building if he hasn't showed up yet. Grab him as fast as you can and start to strangle him . This way, you have eliminated almost the whole Granados family .
Bruce Rivera is still alive (you may not be able to kill him, because no one has information about him in Florida and he's staying on Cuba), as well as the boss himself.
