Fallshirmjaggers, my nemesis
In this replay you did a good job initially pushing off the volks and spios but then followed that up immediately with a 700mp float that crippled you for the rest of the game. You had enough MP and fuel to build a SU76 at 11 minutes (something which you have a bulletin for) but skipped that tier completely when you knew the enemy team had a fuel advantage since they had not put out a light vehicle. That map is not the best for shocks as it has a lot of open ground. Guards and AT guns with SU76 (free barrage vs the zis) would have been a better choice overall in this situation IMO. Also sticky nades.
A paradigmatic defeat
In this replay you start by fighting a spio in a building loosing 2 models. You take the far green cover which is good but better is avoiding them completely. In fighting him there you were fighting on his terms. I assume your teammate is a friend so I hope you let him know the Wehr player had sent his MG to the OKW side. With that in mind the two of you could have doubled up on the north fuel to make sure it didn't get lost. You did a better job this time recognizing the need for sticky nades early but lost both upgraded engi squads by being too hyperfocused on the flak truck. You didnt need to focus on it after the nade was thrown since there was nothing else you could do to it. And once agian I see you floating
700mp 850MP! After 11 minutes i dont think you were floating less than 500mp. Hit a mine? Immediately pull the tank out and start moving AT assets to cover hte tanks retreat.
Something else you could have done is use inf and an AT wall to stall for a KV1.
Ultimately your main problem you need to work on is floating MP. Address this and unit preservation and you will see yourself doing better in game.
