In this case, artillerie would counter this as said earlier.
artillery? you mean infantry support gun? that was already my original suggestion. i sure hope you dont mean actual artillery
Flanking sturm pios.
sturm pios are forced to retreat instantly since 2 snipers take them down to half a squad after the first shot. the flank wont be successful and youll have some expensive reinforcing to do if youre even able to get away.
blobs of volks (but keep them spreaded a bit to avoid grenades) if you like the frontal single unit assault.
like i said before, blobbing will help you force the snipers back, but completely contradicts the whole idea of out capping your opponent.
Keeping the guards busy with an armored unit they can button while you move up. This one is very theorical.
probably my favorite suggestion. "keep the guards busy" aka sacrifice a vehicle
Capping the rest of the map and dodging the blob to force it to spread and then pick it out one by one (this is an expensive, slow and low model count blob) divide and conquer!
they are the exact same speed as your units. the difference is you will be losing mp and running from them every time you see them. you cant run forever.
Ubersoldaten LMG wreck the sniper in a second.
not even going to bother with this one again
as enjoyable as this is, and after having seen your playercard, im going to have to call this. i think the fact your suggestions include the most expensive late game infantry, sacrificing light vehicles into guards and flanking with sturm pios speaks for itself
