Company of Heroes

I know I'm not that good as pro and famous players but I think I'm pretty decent top 100 player and can someone please explain to me how to beat this abuse...

NOTICE: This guy has 31/0 score and I think its all because of the same strat he is using...

You destroyed most of his buildings early on. You knew there would be no snipers/nebels.

You had a MG42. All you needed was a ATG with this MG42 cover to protect your base.

Why no earlier WSC with Snipers??

uhmm
