with first engineer go to fuel point and try to capture it or get in the house to hold the enemy until you go to retreat to tech up. While you hold you can spam mines( 7 muni mine in the infarty paths, like between houses or at the houses door, 30 muni to the main road, choke points,like semois behind the church, it may be familiar to you from coh1)
then go T2, whynot t1? because it has good AT gun not that doctrinal call in inpotent At gun which is useless against heavy tanks,like tigers, tiger ace. Attention, dont bring immediatly At gun, you should bring later,when enemy is building t3. The doctrinal HMG able to deal t2 vehicles.
After t2 go to t4 and bring katyusa. Why? because it is more effective that chasing the enemy with t70, need less micro, and in case you have anti artillery, anti blob weapon.
Then bring 1 su85, bring more in case of tank spam or 1 more katyusa.( i usually bring 2katyusa,1 at gun, 1 su85)
Later if the game went to long,you have lots of fuel, you can build t3 to bring mobile anti inf tank.
doctrinal choice: useless to say, soviet defensvie commander

i forgot to say, tech the molotov, at nade, healing center too. You will feel it when, but after 2 conscript i would bring molotov. and, you can switch the sequence, so bring su85 first then katyusa.
