"Ośrodek Szkolenia Poligonowego Lipa" is a military area - a reactivated firing range. It should be tagged "military=exclusion_zone" as it's forbidden to enter it without official permission from the military. This excludes the main roads running though it (Borów-Łążek, Chwałowice-Łążek, etc) but there are "no entry" signs placed on every intersection with the forest roads.
