Use whichever gun you'd like to as you move on toward the west-northwest. Head back outside, eliminate any soldiers along the west wall and around the corner, and pick up additional MP40 ammunition.
Kill those on the same level as you, and then swap out your SVT-40 (secondary gun) for an MP40. Run through the hole in the wall, and shoot the Germans on the staircase to your left and up above on your right. When everything is clear, charge over the puddle of blood and up the steps. If you can't figure out who's shooting at you, don't forget to check the windows. Take cover, shoot whenever you can, and be ready to return grenades to their senders. Shortly afterward, Germans will emerge from the nearby building and start firing upon you.
They'll start running southwest, and you'll want to stick with them, else you'll get blown up by a grenade that's tossed behind their group. Collect it, then meet with your fellows and listen to the Commissar's words. Prior to actually meeting with your comrades, run directly south of your starting point, and turn left to descend into a dead end.
