Your assumptions are incorrect. I will use your example

If the visibility is set to 11 as in your final example on a flat map you will be able to spot and fire at an enemy unit out to 11 hexes unless you have IR gear. There is no "hindrance level"....the game is set to 11 vis and that is how far you see on an unobstructed map.

On a normal map hills, trees, houses all restrict that maximum visibility. Then battle effects are factored in....smoke for one can offer a lot of variability to spotting because it dissipates from turn to turn. Then toss into the mix the level of suppression that your spotting unit has as well as it's experience level....ALL of that determines a units ability to spot but because this is a game and not reality once one of your units spots an enemy then the enemy's location is known to all...even though it might be an isolated unit but it also applies in situations where there might be other units of yours close by but all of the unique factors that will allow your unit to spot..experience, moral, position on the map, suppression level....all contribute to whether you can see an enemy unit or not .

What you are suggesting would create ENDLESS " bug reports" not unlike the one currently active. Clicking on a unit automatically puts that unit "on alert" because it has been selected
