Yeah that's right,i fultoned every single one of them and used a sleeper sniper to take out the captain.I did it again on EO 107 to get the M202A1.If you like spending time going the difficult and more patient Path with the Smoke Grenade and Fulton Mine,you won't get spotted unless you mess up.But you really don't need to,just fire away with the Fulton launcher.Yeah the chopper will fire at you and you need to stay on your feet,specially if it's a Bomber chopper that flies over you and dropping bombs.The Raider Choppers are easier to avoid though,it fires Missiles and Machine gun so if you stay behind cover you'll be fine.
