ok i have beaten the game now and can help you on anything you want.just post on this topic and i can help you.only PS2.

Hi, I am stuck on the mission that you escort the tanks. You blow the road blocks, kill what Mexicans there are - the ones from the copter too and then the enemy tank comes on the hill and the mission is failed - our tanks destroyed. How do I get the tank destroyed? I can't figure out how to get to that area. I don't have a weapon to destroy the tank from the roof. Where do I go and what do I do? Help, please!
