Common Questions For This Mission:
Mission 5 is more difficult, how can I beat all of them plus the APC?
You probably waited for the APC to unload the bad guys inside. You'll really have a problem approaching the convoy, I suggest running immediately to the convoy and get the rocket launcher before it unloads the baddies.
Objective 1: Destroy The APC Using The Rocker Launcher Found In The Convoy
I did this mission the fast way so I can avoid those guys unloaded by the APC and the baddies from the choppers. When the mission starts run to the convoy and massacre all those who breathe (except you). Use your m16 grenades before getting close and kill the rest. Quickly pick the rocket launcher at the back of the 2nd truck and aim at the APC before it unloads more soldiers.
Objective 2: Pick Up The EMP Chips From The Trucks In The Convoy
After that run to the first truck where the chips are and activate the panel on the back to open the door. Pick the EMP chips and you'll notice two choppers landing on your starting point. That's a No No, because that's not your chopper.
Objective 3: Await The Helicopter For Evacuation
Head far north before more enemies approach you, I ran on the hill north of the first objective compound. Check your map and look for your helicopter (the chopper with #3 in it) and wait for it to pick you up.
