Is there one of the trees as well? Seems like during certain engagements tanks can shoot through the trees and I can't.
Something you always have to remember:
What you see on your screen is not necessarily what your enemy sees on his screen. This is particularly true for the flight path of shells.
Your own shells flight is accurately rendered in detail on your screeen, your enemy's (end everyone else's) is not. It's merely an approximation. Next time you see an enemy (wirbel or any other GV) taking down a town, watch his shells: Often they seem to go right through the town hitting the ground behind it, yet the buildings still explode. And that's the reason while it can seem the enemy is shooting through the ridge of the hill you are hiding behind, when hes actually lobbing his shells right over it.
In short I just want to know without a shadow of a doubt that if I put this round throught this spot on this GV it dies.
In real world this doesn't always work this way either. Of course there a spots that are more or less vulnerable, but even then kills are rarely guaranteed. Distance, shell angle of arrival, the enemy tanks angle relative to you and a few other parameters that you can almost sum up as "luck"...
That being said, M3's in AH seem to be made out of a lightweight ultra-tech armor with an amazing protection factor
