Objective: Weaken the Granados and Tony Rosato: Take over 12 of the Businesses
I remind you that you haven't completed the task of eliminating the enemy soldiers - the strike at the airport prevented you from doing that. You can find some people that need help and gather the required information. After that eliminate the enemy families members (you can read about this in the last chapter of the guide).
However you can start with taking over the Businesses. Start with the diamonds - by owning this crime ring, all of your soldiers and guards (including you) will have a bulletproof vest. Strike the Emilio Packing Company.
Firstly climb the ladder at the side of the building and order your engineer to cut the power off . Beside you will find windows , through which you can enter the building.
Crack the safe and eliminate the guards afterwards. You will find the owner at the top . Take over the Business with a couple of punches. Beside, behind a net which your engineer can cut, you will find a better sniper rifle . Set up a strong defence, even 7-8 guards in every place of the diamond crime ring.
There should be only one place left - Lansky's Deli . Attack the place and prevent the guards from calling for backup  or send your engineer to the box located on the roof.
Eliminate the guards, crack all the safes  and use your fists to take over the Business, set 7-8 guards.
Objective: Find a phone and call the next contact
A new objective will show up before you know it - never the less, finish taking over the diamond crime ring in order to obtain the bulletproof vests. Afterwards find a phone.
Objective: Meet with Fredo at your safehouse in Florida
Drive to your house in Florida. You will find out that someone wants to eliminate you .
Objective: Talk with Fredo
You don't know for sure who it was, but after talking to Fredo think they were Mangano men. You also receive one more capo slot.
Upgrade one of your soldier to capo, find s new soldier
Choose a soldier with a speciality that the first capo doesn't have. If it's possible, it would be great if it would be someone with good gun knowledge. Upgrade him to a capo  and choose a speciality that no one else has (for example - bruiser)! Of course try to quickly fill up the empty space by recruiting a new man .
Objective: Meet with Charlie Green to get into the warehouse
Once more you have an option to choose - you can either follow the objectives or start to eliminate the enemy soldiers and capo and take over Businesses. However there will be always time for this. However it's worth to take mission from pedestrians while cruising the streets. You will gain important info regarding the enemy soldiers that will come in hand later on. The assassinations and beating are by far the easiest but you can also take on robberies and sabotages, but they're more complicated.
Go and meet with Green . He will agree to help you, but not for free.
Objective: Assassinate Hector Santos
You have to kill Santos, who should be quite near Green. Do it quietly - use a pistol with a silencer, strangle or beat him to death .
Objective: Use your connections to enter Mangano warehouse
Drive to the designed place and talk to the man by the bridge . Green already phoned to him, so you don't need to do anything - he will lower the bridge.
