Don't throw your units into the meat grinder.
If you attack a point two or three times and make little progress in breaking your opponent's defence then it's time to change tactic.
Not to interrupt the flow of this forum, but I've had this issue a lot lately. Any additional specifics as to how to go about this would be quite welcome.
My biggest issue seems to be (As Soviets)
1. Germans get 1 or 2 MGs. If I can't flank them properly (through my own lack of skill or bad infantry management) or get a bunker up, I tend to stall out until either I get tanks or they get tanks. Based on what I've seen, I tend to try to go t3, but it seems like T70s don't do as well for me as they do for people in the VODs I watch (hi TFN guys and Imperial Dane, if you visit these forums!) and usually after I upgrade, the Ostheer commander(s) will tend to get out heavy tanks, and I feel like I've wasted my investment.
I know I'm super nooby, but I appreciate any constructive criticism that could be provided. I can get replays or twitch casts up tonight if that would help.
