We can prevent the village's destruction by capturing the enemy's Air Force Headquarters building. The enemy base is heavily guarded, though.  You will not have enough time to build a force big enough to overpower the Soviet defences. You will have to find a way to sneak in!\n\nGood luck, Commander!\n
