Sure about that? In some cases,knive > gun
Well, that's when you have so much volks that you've got more men than they got bullets
so what should axis use,spam inf and support them with P4's?
Not really, you can use what you like to be honest... but players opted to use Super Heavies and Elite Inf (from what I can see... and its working well)
For myself, I simply use infantry & snipers. Arty (hotchkiss, nebel, mortar, hummel [not sure how good it is, never used it]) is a good counter, so are P4s.
There really is a plethora of options available.
