You can see the answers to the first two questions by checking his player card. He plays a lot of Soviet and UKF. I'd bet his answer to the third question is OKW with Panzerfusiliers. PGrens can be difficult also because of their grenades.
Thank you EffenNewbie My question were answered that way
Short Instructions to counter Blobs:
-Mines are great! Forget about the Geneva Convention and spam them!
Just remember that, "every mine shoots down a flying swine
This is especially punishing for 4 men Axis squads.
-Demolition charges are a bit more difficult to pull off. Place them behind buildings, sightblocker or in bushes.
-MG gunner guys are always shortsighted. No idea why, but you need to adapt to that fact. Thats why a MGs always need a second squad to spot for them. ("Spotter squads" give vision and act as a meatshield, keep that in mind. An isolated MG can´t stop 3-4 squads.)
-Since you play mostly allies...well....actually allies are better at blobbing, just make your own awesome blob
-Grenades are good to punish "heavy tactial battlegroups". Try to throw them over hegdes or sigthblockers.
-Any light vehicle with suppression is also great to stop infantry blobs
