Exactly. I definitely wouldn't mark this as the end of stealth tactics. Far from it. Remember that the grass in front of your face that prevents you from seeing anything but rooftops is the same grass in the face of the sniper across the same field. This exploit is only possible if you are in an exposed position, like those rooftops, with a long vantage into grass. In the wide relatively flat fields, there are few features that elevate you enough to see over the grass in front of you. Even if the grass supposedly concealing the other guy exposes him, the sniper won't be able to see unless the sniper is in one of those few and relatively easily recognizable positions that give him that vantage. It is elevation irregularities that expose these long views to a sniper.

That being said this exploit presents a number of tactics that are difficult to counter as infantry. The exploiting sniper in a elevated hide has a ring at ranges ~100m or greater with little or no effective cover that must be crossed by attackers. Even would be counter-snipers don't often have the opportunity because such hides are in the open with no covered, non-hostile approaches within mist range, let alone exploit range. So a single sniper, so deployed can effectively kill an entire squad unable to engage him when prone due to the grass around them. And crouched or standing fire is too inaccurate at these ranges. I am at a loss to think of a counter-tactic to this that does not involve a vehicle.

Other AM riflemen can even know the exact position of the sniper hide and not be able to engage because there is simply no where they can go prone that gives them a clear vantage to the target. Or if there is, his approach will be quite obvious to the exploiter. He would need a long, clear area(a road), pointed generally at the exploiter hide. Then he could stay in the mist range and look for the hide as it appears out of the mist during his approach. Then the counter sniper should get a shot at the exploiting sniper in the first moment he himself would be in danger.

A quick Jeep deployment by a counter sniper into close building cover that allows him to deploy in still-drawn grass was a successful counter. Interestingly enough though an OPFOR tank parked directly under my hide immediately after I redeployed and wasn't maintaining a constant overwatch. The tank was not an effective counter.

This is not theoretical, this is exactly what I did. I don't think this warrants any rule changes as it is just a fact of the game to be aware of.
