If you need help on the last level here is how you can beet it. When you
start there will be a guy on top of a cliff with a grenade launcher.
After you kill him you then go to the left and follow that until you see
an opening on the left. (do not go up on the hill) When you see that
opening go threw it. Then just follow that and it will take you to the
end of the level. Then just blow up the helicopter so he can not escape.
So just wait for him to come and then just capture him. It might take a
while for him to show up but he will come. That is how you beet the last
level and none of your guys died. GOOD LUCK
