View Range ---> Stealth Detection

Does a boosted view range, also boost Stealth detection radius?

In short, yes.

I was looking at the FAQ. Ironically I read this few hours ago but forgot where...

EDIT: 4.6 - Stealth detection

Qu0t3:

Stealth units can be detected if they come within enemy's detection range. Detection is only performed in the beginning of a turn, and discovered stealthy units are announced in the Events menu.

Click on the 'show visibility range' button under the minimap to see your detection range (which is different for land/naval/air units. Detection range is directly proportional to unit's visibility range and also depends on that unit's type.

The bigger the stealth stack the more visible they should become. 200 units roaming around can be seen from miles. 1 a few meters.
