As double Ostheer facing this Soviet strategy one of you should pick Spearhead Doctrine and wait to call in two Mortar Halftracks available at 2 CPs which can harass Soviet Snipers comfortably and escape easily once in danger due to their mobility. It is an comparatively expensive but worthy investment to counter Snipers (as well as basic infantry). The player who does not play with Spearhead should tech to Tier III as fast as possible to bring out a Panzer IV or Ostwind (Ostwind if your foes did not tech up to Tier III/Tier IV) in order to inflict losses upon hostile infantry and to threaten the Snipers permanently. 222 seems not worthy in 2v2 since your opponents can get counters out pretty quickly (Guards, AT nades, mines, etc.) whereas a Tier III tank is able to withstand more damage whilst being not so fragile and mostly surprises opponents who wait for call ins.
Alternatively you can produce Granatwerfer Teams which lack the mobility and flamer barrage. You or your partner can pick Elite Troops Doctrine if you possess it in order to bring one Mortar to veterancy 3 which results into the Granatwerfer Team having more range and higher rate of fire.
thanks a lot gonna try that out!
