There were Germans running over and over

The hut on the right has gunmen at the windows and doors, so hide on the side of the door and slowly clear out the ghosts, during which time some Germans will come up and kill them for ammunition. When the Germans are almost clear outside, hide behind the crates outside the door and throw grenades through the windows and doors of the command post, then go in and sweep in. Go out the back door of the command post and clear out the Germans from the nearby houses.
