I have lost to him THRICE already

Anyways..... my advice is don't rush anything when against Viking... don't take the hills, don't take the good positions, don't take the VHes, nothing...take them much later cuz he'll hit you from long-range and slowly very slowly but inevitably move forward and roll over you, with infantry and everything. Beware of the Quad .50s too.
OK,OK, I'm out of this thread, sorry for interrupting
