Kurt von Schleicher
Bock stayed on as an officer of the post-war "Reichswehr", and rose through the ranks. In the 1920s, Bock was together with Kurt von Schleicher, Eugen Ott, and Kurt von Hammerstein-Equord a member of a secret group known as "Sondergruppe R", selected by and responsible to Hans von Seeckt, who were in charge of helping Germany evade the Part V of the Treaty of Versailles, which had disarmed Germany.
