Thanks Don and Andy. Lots of good information there and explains other odd events that happen periodically. But I still find it strange that units can spend a whole turn firing at each other through a hex with visible smoke but have their LOS blocked by non-visible smoke. Presumably visible smoke is denser.

Also, just what does a height level represent, 1 meter, 5, 10?

In this case there was an infantry unit moving down that road before there was any fire or smoke present and it couldn't see the 75 until it got up on level 2. Does it mean that blocking heights are different for different types of units?
