Bomb one of their casino businesses in Florida, then take over the casino business that is not bombed. Take over one of the gun running warehouses and bomb the other. The bombed casino business should be reopened by now. Take it over before more guards are hired and wait until the bombed warehouse is open. Takeover that warehouse. Go to Cuba. Take over the remaining two Mangano businesses. Go back to Florida. Go to the Mangano compound and bring one Bruiser, along with two people that have more than one specialty (for example, a Demolitions Expert who also knew Medic), and a Safecracker (another Medic). Make sure they both know Medic so you don't have to worry about anything if one of them goes down along with you. Note: Do not let them go to New York. If they get one of your businesses there, they will start spreading rapidly. Also, if one of your businesses are attacked by the Manganos while you are going to take over a Mangano business, send in your men and simply wait outside of the business you are going to take over. For the Manganos, you need all the help you can get.
