Many people reported connection issues in the last days, the servers appear to br screwed in some way. Probably related to this issue, but then again I'm not a tech guy
About the first picture: Does it really happen almost everytime? Or just from time to time cuz then it's normal. (it can happen if 1 of the players has horrible connection or if someone presses Alt-F4 early enough)
And about the second picture it's the same question: Does it happen always or just from time to time? Cuz lately, nearly all of us encounter these server issues from time to time
USF have the best spammable core inf in the game, very good long range M36 tank and Rengers (rengers are very effective), now if you use Pershing + 2x M36 + inf you can win every game. this is my favorite tactic and is tested.
