Totenkopf Skull Badge for Cap

In the early days of the NSDAP, Julius Schreck, the leader of the Stabswache (Adolf Hitler's bodyguard unit), resurrected the use of the Totenkopf as the unit's insignia. This unit grew into the Schutzstaffel (SS), which continued to use the Totenkopf as insignia throughout its history. According to a writing by Reichsführer-SS Heinrich Himmler the Totenkopf had the following meaning:
The Skull is the reminder that you shall always be willing to put your self at stake for the life of the whole community.
The Totenkopf was also used as the unit insignia of the Panzer forces of the German Heer (Army), and also by the Panzer units of the Luftwaffe, including those of the elite Fallschirm-Panzer Division 1 Hermann Göring.
Both the 3rd SS Panzer Division of the Waffen-SS, and the World War II era Luftwaffe's 54th Bomber Wing Kampfgeschwader 54 were given the unit name "Totenkopf", and used a strikingly similar-looking graphic skull-crossbones insignia as the SS units of the same name. The 3rd SS Panzer Division also had skull patches on their uniform collars instead of the SS sieg rune.
