"Roll dice and kick ass!"
To quote the rule book on terrain hexes:
Walls: Cover; none, or 2 if a Fire Attack crossed the wall as it entered the target hex (not applicable when firing Mortars or Artillery). Do you only get 2 cover when hiding directly behind a wall ( and a wall isn't for instance two hexes away)?
Correct: the wall must be one of the hexsides of the target hex to give cover to unit(s) in that hex.
LOS: Obstacle, or Clear if the wall is one of the six hexsides of the sighting or target hex.
I'm reading the rules not having a copy of the game so these questions might seem dumb. LOS would be clear if the target unit had walls on sides that are not directly between the target unit and my firing unit?
Yes, LOS would be clear in the situation you describe. If a wall is a hexside of firing or target hex then it doesn't block LOS into/out of that hex. Otherwise- ie. if the wall is a hexside of a hex somewhere between firing and target hex, then it is an obstacle.[/q]
Can you fire at a unit hiding behind a wall? I mean it says LOS: Obstacle
Yes, because a wall isn't an obstacle to LOS to/from the hex in which the wall is a hexside.
Please shed some light on this!
Hope all this helps.
