Well I bought the game and skirmish is pretty hard. I won my round. Really my tip is to rush the enemy. What I do is setup very good defences, machine gun nests etc. Then I build more and more Tanks and what not and rush the enemy then send my troops in to cap the point. I had around 30 Tanks that I rushed in with lol, they didn't expect that and I easily wiped them out. Btw playing as Axis and selecting the Terror doctorain I think it is gives you a V1 bomb on the last part of the command part. Thats what I use to wipe out the Shermans, they are a tough nut to crack.
