Target Elevation Table

Here is something I've been wanting to do for quite a while, a game aid for PB. This is one of several, and probably the easiest to get started with. A good side effect is that I get much more familiar with the rules as a result of ensuring the game aid is correct.

Note A

When firing FROM a hilltop or slope TO a ground-level target, the Line-of-Sight is obstructed if the TARGET UNIT is directly behind a Gray or Green hex-side: i.e. "directly behind" means that the intervening Gray or Green hex-side(s) forms one or more of the hexagon sides of the target hex itself.

Note A is the converse of Note B.

Note B

When firing FROM ground-level TO a target on a hilltop or a slope, the Line-of-Sight is obstructed if the FIRING UNIT is directly behind a Gray or Green hex-side.

Note B is the converse of Note A.

Note C

When firing FROM a hilltop TO a ground-level target, the Line-of-Sight is obstructed by intervening Brown hex-side symbols if such a symbol is closer to the TARGET UNIT than to the firing unit or if the symbol is exactly mid-way between the two. To determine the relative position of the Brown symbol, count the number of hexagon SIDES through which the Line-of-Sight is traced (including the side of the firing hex and the side of the target hex).

Note C is the converse of Note D.

Note D

When firing FROM ground-level TO a target on a hilltop, the Line-of-Sight is obstructed by intervening Brown hex-side symbols if such a symbol is closer to the FIRING UNIT than to the target, or exactly midway between the two.

Note D is the converse of Note C.

Note E

The ONLY case in which a unit may trace an unobstructed Line-of-Sight through more than ONE Orange (hilltop) hex-side symbol is when both the target unit and the firing unit are on hilltops. In all other situations, the LOS is obstructed if it must be traced through more than one Orange hex-side.
