Question: Soviet infantry bt vs. infantry/tanks

[Wiking]

You've certainly set yourself a tough row to hoe! Like Imp said, your lack of experience will make things harder than it would be even as the Germans or Japanese. The engineers in particular are somewhat lightly equipped at the start of the war, and their poor morale doesn't help either. I do think that playing a purely infantry force in WINSP is difficult prior to the advent of launchers, but it is doable if you really want the challenge. Most of what Imp said is sound advice but I'd add the following:

Your BT's can handle anything any other country out there except France maybe can throw at it. They have essentially no armor for all practical purposes, but their incredible cross country ability and speed coupled with a fairly good 45mm gun means you can position them almost like self-propelled anti-tank guns if you're clever about it. The main thing to remember is that with their low experience, they'll do better if they get op-fire instead of trying to have them shoot on the move. Try to position them and then let the enemy come to you.
