History
It was unknown when did Section 9 was founded, but according to the files related, they were founded as a special unit to assisting SAS 22nd Regiment during Operation Nova Prospekt.

Although the unit was still active, it was put on-hiatus after the Nova Prospekt case has been closed.

In Episode 7 and 8, Section 9 was rebooted to joint operates with Special Assault Team and Tokyo Police Department in an effort to suppressing the terrorist act inside Tokyo Station.

Since Episode 9 and later, the team has officially dismissed entirely, in favor of Team Alpha's multi-nationality task force until General Hirashi betrays the team and puts it in the "domestic terrorist" files.
