Conflict Denied Ops

This is a story line achievement. After you have planted both remote charges in the submarine facility, you will be told to get to the extraction point, which is about 270 meters away. As you are just about to reach the extraction point, someone will say over the radio that there is a hostile jump-jet in bound. You MUST destory this jump-jet (press the B button to switch to Lang and then hold Y to bring out his heat seeking rocket laucher) to secure the landing point, so your friendly chopper can land and pick you up.
