Answer:
The Hitler-Jugend (Hitler Youth) was a branch for German boys that trained them to become "men" and loyal servants of Adolf Hitler. They marched in rallies and trained for combat when the impending war was eventually to come. They were given knives as well that showed the boy was a part of the Hitler-Youth. It was created in 1922 and those who had joined early eventually became members of the SS (Schutzstaffel) or SA (Sturmabteilung) but most likely in the German Wehrmacht (Regular Army). During the end of the war in 1945, the Hitler-Youth advocated for an all-out war, sometimes allowing the kids of the program ages such as 12-17 to fight and defend their cities.
