Camo and wheels are ugly.
So's your faec!!!!111!!!11!!1! >:O
That's what a noob would say... I agree with the tires, but I like the camo. The tire needs more... texture in it. Like treads, and a black color.
Why not a 105mm Howitzer? :D
Because that's a cannon that goes on an AC130... and AC130's CARRY Humvees. It wouldn't make sense to have 105mm cannon inside an airplane with a 105mm cannon. Plus the kick of the cannon would most likely knock the Humvee over. I'm such a smarty!!!

EDIT: The cannon is also gigantic. It would send the Humvee off balance.
No.
