You check the progress of the attack on the east street. The situation there is better, but only slightly. rubble lies across the street in several places, allowing a couple soldiers to crawl from cover-to-cover, but crawling is slower than running for your life, and so the attack hasn't gone as far. You'd probably be able to make it across without losing too many men. Still, you decide that heading through the ruined building is a better option at this point.
You order one of your riflemen to execute the old Helmet-at-the-End-of-a-Rifle trick. The helmet comes back unscathed, so you order the remaining sub-machine gunner to go through the hole, followed by the rest of the squad.
The upper levels of the building have all collapsed, but on the ground floor the walls are more or less intact. After finding some cover behind a pile of rubber, you quickly check your objective. The next house is in better shape, with most of its superstructure intact, meaning that you can't see inside. Judging by the amount of fire that the building is spitting out, you assume that the Germans are definitively holed up in that building. The roof of the building is more or less destroyed. If you had a couple mortars you could probably lob some bombs into it.
As far as you can tell the building has only one entrance, a heavy wooden door facing your position. The building probably has another door leading out onto the street, but which street is a different question altogether.
