If you keep the Ost Sniper alive until Vet1, it can use its normal shot + vet1 to doubletap the Soviet sniper team.
Well thats the freaking problem... Ost sniper was bad idea agains Soviet even before it got nerfed... Its even more taxing to micro and keep it alive, it gets badder as there is Soviet-scout sniper shooting at you, that god-forsaken 120mm mortar if not blasting you then flaring you out of cover... And of Yeah there might even be that intercource with those double penals or more that can one volley kill that poor sniper...
Adamircz's advice is spot on, push with Grens and flank with the 222. There's a good chance to pick up the sniper and probably do a good chunk of MP bleed to the Penals in the process.
I just had OST who used that strat against me with Counter-Sniper, 222 flanking, double engis flanking, triple Grens pushing trying and even MG42 trying to make movement hard... Well got some easy demo kills, one and one captured MG42...
My conclusion on the new Penal+Scoutsniper BS is that russian sniper should lose it second model and make it in bar with ost and UKF snipers...
