Question - What Counters the Stealth Special Rule?

[AZKAMAT]

Well? What I mean is, are there any abilities that nullify it directly? I'm looking for something along the lines of "ignores Stealth" or "removes the automatic 1/3 cover bonus units with Stealth gain when out in the open."

And yes, I'm aware explosions are good against hordes of stealth units.

Tracking
Tracking Specialty: Cost:+1CP; automatically Detects Stealth; allows Marking of targets for +1 Attack Bonus
Besides being masters of Stealth, the Scouts' keenly-refined paranoia and sixth sense for danger also makes them masters of Detection. Except when the Scout is busy with remaining Hidden himself, the Stealth bonuses of any enemies within his field of view are canceled, and hidden and Invisible units and objects are automatically revealed to him and his allies.
