Thanks for the vid Viper. I don't know if that tactic would have been particularly viable in the server last night due to other unknown threats but it's good to know in some way that it's possible.
While Magnum did pull off some impressive shots from cover, before I left (as a shark pilot) we ended up pulling in SU-25Ts and just launching 4+ HARMs at single targets to take them out.
I'm still not entirely sold on their high level of effectiveness, but I'm also not convinced the feature itself is way out there.
