First of all, remember that you need to follow the 'Who can Shoot' rules on page 13 of the ORB. Secondly, if you can see the target, most walkways or 'level' flooring will get the target partial cover, but if the target is under the template he is hit. Remember that a flamer ignores cover so the walkway would not prevent the target from being hit.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
