Having a tough time with enemies? Well, all you have to do is choose an air strike that uses a sattilite and scout out enemy positions (they are little greyish brown guys.)this really helps when you are finding the third ace.
Get a sniper rifle and infinite ammo (optional) and get on the U.S.'s bad side and go to the us mash stand on the hill near the cliff with a high way below and wait for a helicopter and then shot the piolet the chopper will swing out of otroll and crah some times up right to take.
Ok for this you need to be at the U.S mash and need 4 c4s. Go to the right where their is a cliff and below a high way. Kill a civilian and put the car his in the middle of the road, put a c4 charge on each side, front back left right, get up the hill and look straight not at the car and pull the trigger it will send the car flying like a rocket.
