The problem with snipers is the disruption they cause which can slow down the game if they are used correctly, particulary if you dont have any vehicles.
If you cant see him fire arty light mortars (AGLs in MBT) & Z fire usingthe furthest unit.
Anything to raise his suppresion making locating him easier.
Kill him with MGs or by getting close, hence the smoke, better yet if you have vehicles (especially accurate ones in MBT) hide & let them get an easy kill,
snipers die fast vs a high tech armies autocannons & tanks. They are much more of a headache in WW2 due to its more infantry based nature.
The good thing is the disruption they cause is expensive snipers rarely kill their point cost. Cheap ones (no fire control) dont kill a lot.
5 FC often cost more than a squad so have to kill 8 plus men. etc
