It usually pays to overload one flank, simply because you will take no fire from off the edges of the map. Sometimes you'll take victory hexes well behind the first line of defense, earning additional honors for your leader. Position most of your bazooka teams in the center of the map, a bit to the rear, where they can quickly rush to wherever the enemy armor might be. Use your own armor with care, but don't be too cautious. You have far more replacement armor available than the Germans, and a failure to use these powerful resources will make your struggle only that much more difficult.
Tanks are particularly effective against enemies in pillboxes and stone buildings, as are bazookas.
Don't move tanks closer than sixty or seventy meters from German infantry positions, because within that range they'll use their Panzerfausts on you. Stand twice as far from Panzerschrecks. According to Atomic, each inch on the screen is 15 meters, at 800x600 resolution. To get your tank to go in reverse, issue a Move command just a little behind the tank. Use your mortars against Germans hidden behind hedges, firing just a little behind the lines.
