To remove insensitive zones of the police radio, the Squad installs temporary radio relay stations. They install surveillance cameras and operate helicopter television systems that enable police officers to grasp the detailed situation of the distribution of the units, surrounding areas and to prevent accidents in crowds from occuring.
  In 2017, at the 68th Zenkokushokujusai (tree-planting ceremony), the 72th Kokumintaiikutaikai (national athletic meet) and the 37th Zenkokuyutakanaumidukuri (nationmal meeting for the healthy ocean) to which Imperial couple made visits, the squads deployed relevant organizations contributed to the police activities like securing Imperial couple and preventing crows from an accident by transmitting the images of the concern, installing temporary radio relay stations to remove insensitive zones of the police radio and so on.
