Corrected some spreads. All shotguns do enough damage to kill with one shot again.
[Edit]
Someone suggested a
Kamov Ka-52 some days ago (a russian attack helicopter). What about that one or the
Mi-24 Hind?
Not part of the pack, but I never made any flying vehicle yet. The pilot would be able to shoot with the main gun and the co-pilot would have control over laser-guided rockets or something. Long time between shots, and the rockets would basically be able to "lock onto" vehicles and points at the landscape. Then the pilot wouldn't have to aim directly at a point or vehicle to shoot it with rockets.
