Here is a conversation I has with Martin at PP, about LOS in squarebashing
ME >For weapons that have a range >1 (artillery , mortars) do you need to keep LOS? is that from centre of the square to centre of the square
Also, can you shoot over intervening troops (friendly or enemy)
Martin >Guns can shoot overhead of other troops but cannot shoot over hills, buildings and woods.How’s ythat
ME >So, Martin, do you measure from square centre to centre to determine LOS through trees etc? or can it be any part of the square that blocks LOS?
Martin >Square centre to square centre. Of course it might TOUCH the corner of a wood square etc but that is OK. Thus a diagonal of squares can ignore buildings etc that touch that diagonal
