@Melonhead: Excuse typos, at work.

#1: Post clearly states: "in front of the APC"

#2: Most APC's are back loaded. It's simply the most practical way to design a metal box with soldiers in it. Still, I will keep in mind to mention such details in the future.

#3: Knowing where the wolves are (attacking front of APC) and knowing where chainsword bastard is, (back attacking door) we can deduce you are viewing the side of the APC via geometry. Through extrapolation, we can deduce that even if you don't know where the door is, you know that if the chainsword beastie went around a side of the apc and you were viewing the front or back, you would still be able to see him. Therefore, for him to vanish from sight without chameleon, you would have to be viewing the side of the APC.

You have all the details you need mate. Just didn't read it correctly and I didn't clarify that standard APC configurations put the door on the back.

Hope that clarifies enough.
