Kasukabe Defence Force: Futaba Headquarters
Kasukabe Defence Force's Mobile Fortress SP-X
The Kasukabe Defence Force or Kasukabe Defense Organization (かすかべ防衛隊 Kasukabe-bōeitai), also known as the Kazhukids in the Vitello, Phuuz and Dutch dubs, is an "organization" that Shin-chan and his best friends created in episode 143.
The purpose of this group was to promote peace in the city of Kasukabe. However, this so-called organization is little more than just a name for Shin-chan's clique and often they hardly do anything meaningful during their operations, but they ironically cause many troubles when they do "defend". They also want to protect Kasukabe and the world. Their secret base is located at kindergarten teacher Midori Ishizaka's house, and she is also known as the group's manager, much to her chagrin. Even though they usually bicker and fight about who is going to be leader, eventually Shin-chan is the leader as he mostly stands in the middle when doing something important or shouting their slogan while the others follow. Plus, they had a fixed standing position when shouting their slogan as shown in the movie 2004 and 2015 where they stand according to their position naturally. Kazama is not seen in the scene but they naturally left a spot for him. Their position from left are Masao, Nene, Shin-chan, Kazama and Bo. As you can see, Shin-chan is in the middle. Also, Shin-chan is the one who first remember this group and their slogan when they forget everything in the movie 2004 which brings back the group's aura and teamwork. It's something a leader will do. Furthermore, it will only be logical and make sense if the main character is the leader. Moreover, the producers, directors and staffs of the show confirm that Shin-chan is the leader as well.
Their rival is the Kasukabe Guardian Force, which appeared in several episodes.
In the English Funimation dub, known as "Kasukabe Defense Corp" or "Haruhibu Military Corp".
