Hit the beach and help wipe out the resistance. When that's done, get up the hill, enter the tunnels and find that intel. When done, go through the forest and find POW camp. Take the guards out and rescue the POWs. Go to the beach and take the boat back to the carrier. Report to the commander to finish.

A couple of lame problems at the start with this as there are quite a lot of things in the water. But if I took them away it wouldn't look so good. If you trun your head to one side the lame problems seem to vanish. Once you're on the beach the lame issues go away. Enjoy it!
