I don't really care about the heavy MG, it's not too bad to face. But fuel-cheating commanders always piss me off. Opel, Industry and now Lend Lease. It seems to trivialize map control. The sherman will get a small nerf I'm sure next patch, but even so, I think these commanders are conceptually problematic. People used to whine about the Brit trucks and secured resourcing in the first game for similar reasons.
1. Get a scout car.
2. Upgrade to 222
3. Watch how the supply planes get obliterated.
I guess fuel caches also piss you off.
