This is an incredibly powerful helicopter gunship that is armed with rapid-fire 30mm cannon (grenade launcher), anti-air missiles, anti-tank missiles, and dumb-fire rockets. You must have an anti-armor rifle and a RPG or anti tank rocket. Grenades work somewhat, but are not recommended. You cannot use an anti air. Find one flying (try the North Korean Allied MASH, when you complete the second ACE contract you will "unlock" this). Once you are there, find a YAH-56 Gunship with the binoculars. Then, go to it and make sure it is over flat land. Take out your RPG or your anti tank rocket and shoot above it. It will fly down slightly. Then, take out your anti armor rifle and shoot the pilot (located the back seat of the helicopter). If you cannot see him through the glass, shoot under the cockpit. Once he is dead, you will have about $25, 000 depleted and your helicopter should land on the ground safely. Try again if it falls on its side or something else happens. Do not be afraid of the tail rotor. If it is half way in a rock, it does not effect it. Note : This strategy can be used with any helicopter.
