You pretty much hit it on the head yourself when you said you lost from losing squads to commander arty and map control. Personally I wouldn't have gone MG, Volk, MG. You also starting researching skirmish before getting your second volk squad which delayed it slightly. It would've been better to get it first to help you gain back some ground. Defensive was also a poor choice in my opinion, as I've had bad experiences against Soviets using defensive. The mortar did well and you were unfortunate to lose the halftrack, though it arrived much later than it should've. You should also never put an MG in a building against Soviets, you will simply not be able to leave in time.
