Smoke Effectiveness?

[ComradeP]

LOS can go "around the corner", so unless both hexes along a hexside are blocked by smoke, a stack over 50% stacking limit or terrain, you'll be able to see the hex on the other end of a hexside as seen from the hex of the spotting unit.

This can make placing smoke to block the LOS of units that are located along a diagonal line from your unit tricky. I tend to load another instance of the scenario and place smoke to see what works and what doesn't for those situations.
