Hitlerjugend: An In-Depth History: HJ-Invalid
by Arvo L. Vercamer

The HJ leadership quickly recognized that a small percentage of Germany's youths suffered from type of medical or physical challenge, such as loss of vision, loss of hearing, etc., through no fault of their own. To encourage these individuals to join the HJ movement, a special HJ-Invalid organization was created. It contained a main parent organization and two sub-components for vision and hearing impaired members.

Reichsbann "B" (Blinde) was for the vision impaired.
Reichsbann "G" (Gehöhrgeschädigte) was for the hearing impaired.

Members of the above cited HJ-Invalid groups wore a special shoulderboard indicating their status.
