Maybe simpler, but it does make gunships etc very easy to kill... although then they'd be AIR for AoS, so I guess by that reasoning you'd target them with SAMs only, whilst identical in movement and capability AIR movement mode units are targeted by everyone as normal
Ahhh, the joys of rules wrangling
It's at least 18 months since my "Red SkY Squadron" took to the field and I'm not sure anyone actually managed to shot at them then anyway!
