Just finished the CODA mission... the trick is to help the Mi-24 to stay alive because I think they destroyed the buildings on Abraham compound (i didn't, neither my wingman). What I did was to take down at least two AA's in the convoy before the Mi-24 come close to it. Then, go to the base, but atack them through the north side, where they are not concealed by trees, hiting them by far. The problem is my wingman is always refusing "atack air defenses" orders, but if you get dangerously close, he will atack them. The helicopter took of a few minutes after we took down a couple of targets and we followed it and my wingman took it down, aldo I got a good lock and fired one vikr (but he dodged it). Mission complete!
However, we still had fuel and amo to go back to the base, and we did and kicked some more ass. One Mi-24 kept flying arround, he survided the mission too :)
