Russians seem to to quite well for close range (More chance of critical hits), so use G43s and Vet them only offensively, and use MP44s and vet them defensivly, go TD, get some Hetzers (If nessecary) and definitly get some Marders, but what ever you do DONT BLOB!!!! You never will need more than 4 squads (3 G43s and 1 STG44)
Use Armored Cars for Support and keep it BEHIND your infantry, and keep a HT safely behind your main force, P4s arent too good against Russians (Because the squads are too large), so you might be safer for using a Hotchkiss (Get nebels).
Get Panthers ASAP, the T34s are fast and will destroy your Marders and Hetzers. Use your Panthers wisely by having a Marder behind them, and lock it down. 2 Panthers and 1 Marder can defeat an IS2, 2 T34s, and an Upgunned T34, thats ALOT of Fuel and MP on thier side, and you may loose A panther and Marder, ALWAYS defensively Vet your Panthers, and Offensively Vet your Marder.
Ive never made a Mortar HT against Russians, they tend to get too close to your troops and they spread out too wide when they "Get on line" Scout Cars however are a critical if they use Snipers (Obviously). PE is a GREAT faction, you just need to know how to use em.
