campaign scenario setup help

[Ts4EVER]

Ok, the big finale in Russia...

So close and yet so far... the frozen terrain and strong Russian counterattacks finally stopped the great offensive before Moscow could be taken. What's more, the Russians brought in reserves from Siberia and forced us to withdraw. Now our front is under attack at several points. Not even the thought of service in warmer areas can lift the spirits of your men, as you are tasked with holding a quiet part of the front, along a major river. Only occasional sniping and the nightly attacks of those blasted biplanes attest to the presence of the Bolsheviks.
Recently the river has frozen over. This gives you an idea: You will not leave the Ostfront without a final feat of heroism. Radio intelligence confirms that there is a Russian command post in a major school building in a village behind the lines. You will pick a special force of platoon strength from your infantry, let them sneak through the lines in the night and take out that post. The rest of your force will hold the western bank of the river against similar Russian incursions. You have three bunkers at your disposal which you can place whereever you like.
