Start in the south, where Preiss and Hellmann once again can do the job on their own against the Flame Bunker (notice that it’s low on power because you took out the Power Plant?), the Wurfrahmen, and the less-than-enthusiastic guards. Move the dynamic duo to the southern entrance of the Research Facility to lure out and obliterate the Flammwagen APC. Guards will come running to attack and then, like everywhere else at this odd place, turn and flee into the snowy woods. Advance closer to the southern base entrance and guards from the other side of the base will also come to investigate—and they too will head for the hills after just one taste of Hellmann’s rocket launcher.
Now circle in a clockwise motion around the map and deal with the guards at the northern entrance to the base. Weakened by the sentries who ran to the south earlier, you should be able to easily defeat these guards and their Flammwagen by luring them into an ambush a bit up the road from the checkpoint. Just arrange your troops and APCs in a semicircle and send Hellmann close enough to get their attention, and they’ll walk into a crossfire that will cut them down (or have them running like cowards) before they even get off a shot.
