Stratos, Try using what the US Army calls 'marching fire'. Use the 'z' key to shoot up suspected ambushes with area fire. It won't kill anything ( maybe once in a blue moon, if you get very very lucky) but it will put supression on hidden units. That supression will make it harder for them to see you and easier for you to see them. It will also lower their to hit percentage when they do open fire.
This isn't 'gamey', since Rommel and Patton Both demanded it of their troops while advancing. On defense, it just gives you position away, but it's great when on the offensive.
I have no idea if this was Soviet Doctrine also. The Soviets had a LOT of logistics problem before mid '44 when the US got the supply line thru Iran working and sent the Soviet Union a bunch of trucks.
