Clear the nearby small building again

Go to the first floor window and snipe any remaining German soldiers in the bunker. Finally attack the German command, return to the northern street and find a residential building, your teammates will come up and kick the door open, go through this building to the estate area north of the town, use the fence to move in on the target small building in layers, there are plenty of bunkers near the small building, use them to throw grenades at the windows and then go in and sweep.
