If you get in the cockpit of the helicopter AH-9 as a pilot and you pass in the third person, you can see the missiles come out a little bit from the launcher. They disappear when you look in the first person. The problem is only for the pilot seat with any soldier (east or west), any class.
Third person view outside vehicle OK
