i will try to describe where the window is, as you leave the allied spawn and you see on your right a building with two archways, one has sandbags blocking one arch while you can run through the other. you can continue out the building by using the exit ahead or you can go upstairs, if you go up the stairs you pass two windows, keep going around the corner and there is a single window which you can shoot out and look down the road toward the direction of the center flag. this window is clear if you look from the inside but if you look from the outside the shutters are still in place and you cannot see the sniper at the window.
if this explanation is not clear enough, (which is more likely the case),next time i see you in game i will show you.
Excellent description Smegga. I found it right away.
The problem is that the inner shutter is breakable, but it is not tied to the outer shutter, which is not breakable. Thus, you can see and fire out, having broken the inner shutter, but can not do so firing in, as he shutter will absorb the bullet impacts..
The solution is either to remove the shutters entirely on both sides, or to tie breakable shutters on BOTH sides to the trigger.
