Put this clip under the marching or group-walk section itself, not over the introduction. Follow it with a short drum sting when the group stops, and place a brief alert sound just before it if the scene cuts suddenly to the formation.
O tym dźwięku
This is a 34-second excerpt of "Wenn die Soldaten", a German marching song performed with male vocals and a brisk band accompaniment keeping a steady parade rhythm. It feels rousing and old-fashioned, cheerful on the surface while carrying the stiff, formal energy of soldiers marching through town in formation together.
