No... We have trees and some shrubs... Look at the "clever SOB" image... If that were modeled in AH, you know what we'd have? A giant porcupine sticking out of a flat terrain.
AH doesn't have ditches, draw, gulleys, ravines, natural land formations you can just roll a tank up to and remain mostly hidden except for the gun barrel. We don't model all the millions of natural real-world elements that conceal your location (sometimes) in the real world. This is not a ground combat simulator. They were tacked on as an afterthought, almost. They've developed into a fun part of the game, but by no means is it very realistic.
Again, it's trying to interject a no-icons request into a thread totally unrelated to it. If you set up a wirble in real life like we have in AH, put it in open fields where it's firing at you, put it near trees, buildings, of similar size and shape as AH has, and there's no damn way you'll miss it.
You want camouflage, take it to the wishlist forum. Don't go claiming GVs ought to be invisible to planes just because you don't like being bombed. (I say this to "You all" not just "you" -- as it's a common thread in all these GV icon threads)
