Like Grenade Launchers, Grenades and the best are the helicopter missiles. Now destroy it with anything that makes a bang. Inside the cargo door, you will be able to see something greenish. (I hope that you know how to place the C4 charge) When the charge blows up, it will blow the cargo door as well. Place the C4 charge and run as far as you can from the doors. (The objective marker may seem to point on the cargo doors but thats wrong, its pointing on one side of it.) Once you are there, you will see a place for the C4 charge. You can see a objective marker on the cargo doors too. Land on the ship after that, go to one of the cargo doors. Before landing, you can see 2 red doors from above.Those are the cargo doors. Now, to do that, you have to land on the ship and go on foot. Destroy all the patrol boats and after destroying each and every one of them, another objective will pop up. To blow up the cargo ship:First of all,when you approach the ship, there will be an objective to destroy all patrol boats.
