If you commit your troops too early you will risk running out of troops before the end of the battle. Patience, grasshopper! In this one I committed the Soviet tank forces too soon and watched them vaporize 1/3 of the way in. The Germans then methodically (is there any other adjective when discussing 1941 German army efficiency?) mopped up the rest. A less impetuous Soviet defense could have caused much more of a headache to the Germans. I'm afraid that my silly use of armor handed this one over on a silver platter.
