look at the most recent replay posted. The enemy team had a jagd, a vet3 kt, and 2 tigers with multiple repairs. Those are also top EIRR players with those tanks.
On a side note, its silly to expect to not take huge losses vs 4 elite enemy tanks like that...
EDIT: Also, used a balanced company.
saw the replay that was not even close to a heavy armor spam.
Again if anyone can post a replay on how the US can stop a blob of heavy armor (KT, Jagd, Tiger, etc) more than just one time. Like a repeating wave of them, then please post. B/c i dont think you can unless you got 7 ATGs per company. Which ofcourse leaves you defenseless against inf. Blobs of heavy armor just run over everything.
