It is not a problem for a UAV to fly in light winds or fog (depending on the quality of the payload). However, the parameters for a sniper to make precise shots are very specific. The slightest change in the weather directly affects their ability to hit their target.
Meanwhile, you can develop a tactic with more than one squad, independent of each other, taking off via cable and monitoring different areas. Thus, you ensure situational awareness at the company level.
Sniper shots in these situations are really very difficult.
The most stable position is prone supported, or any other modified supported sitting position where the muscle relaxation is at the maximum level. The problem here is that the drone operates at a higher altitude and there will likely be trouble with finding suitable conditions for a supported position that will allow taking a shot in such a steep angle. Also the drone is a little target and must stay steady in order for the Sniper to have a chance to take it down.
TSK is dealing with drones for sometime now and thankfully PKK drones are of low quality so their success is small. TSK found solutions in both anti-drone EW "guns", but most importantly some of the units depending on the mission are deployed with a shotgun as a hard kill measure. Usually an ARMSAN RS-S1 is delivered to the units.
When it comes to an air defence system there are a lot of solutions already both in terms of soft kill and hard kill. If we talk about a self defence measure on platoon level I think the best solution would be a shotgun. In certain scenarios there is a dedicated breacher that carries a shotgun. It may be full sized and underbarrel. Judging by the developments a small shotgun will start to take a place in the default configuration within a platoon. Anti-drone EW guns may be good, but they are too big to be carried in a offensive scenarios. A stationary position is better suited for it while the shotgun is both able to shoot down drones if they are close enough, but also can be used in other scenarios with different kinds of munitions.
