I did a pic to try and show what I think the cover rules mean,
The Wood is Med-Heavy So couunts as Cover.
If the wood was instead light scrub, I would be inclined to say Obscured and LOS for all.
Using A as the Active Model.
The Distance between A & D is 1" or less
They have LOS to Each other, Both also have Cover from each other
A to B & A to C are the same (goofed the drawing see below)
A to edge of woods is less than 1"
A has LOS to B & C, A is in Cover, B & C are Obscured
A to E
There is no LOS, to much woods
C to D
C has no LOS to D as there is too many " of wood.
If the woods between A & B was over 1" then they would not have LOS.
(which I meant to draw but goofed)
If E was a size 3 or greater, (and the distance between D to E was 3" or under) Then E & D would have LOS to one another, and both would have cover.
This is again what I think is meant.
This also works for models in buildings, as cover takes many forms.
