The obers getting wiped was just unlucky. Any indirect fire weapon can do that, even say a mortar.
The other two were just a-moving blobbed volks into specialist anti infantry weapons.. Yeah, perhaps you shouldn't do that...
Most weapons will do these kind of things nowadays, PIVS, tigers, t-34/85s, you name it.
blobbing? no. I will upload the replay if you want, it's not blobbing or a-moving (I very rarely use a-move). The USF player was blobbing 5 rifles squad together, I was simply moving my AT towards his tanks. in fact you can see his blob in the first gif
so now I can't even use my inf is what you're saying? just leave them in the corner in case of squad wipe.
The only tanks I've seen wipe like that are IS-2 and Tiger I, besides scott.
