The key is prioritizing the MG micro over units micro (since that's the unit he wants to kill first anytime) and continue to apply damage till level 1 pops up.
Also remember to always retreat units in time, even if it means losing all the map for a while, but be ready to massively push forward and regain all the territories as soon as you have enough forces.
Featuring a recrewed vet3 MG42 with 32kills, effective use of medpacks from grenadiers (they heal each other incredibly fast even under fire!) vs 4 conscripts squads with PPSh + Hit the Dirt + molotovs with increased range bulletin. At some point I thought he would have switched to tanks (so I prepared a pak and a PG squad just in case) but instead he prefered to go for Guards/Maxim/ZiS-3
Hope you enjoy (at some point I had too many units xD)
