Section 9

Japan Ground Self-Defense Forces' Tactical Advising and Counter Terrorism Act Special Unit, morer commonly refers as "Public Security Section 9", often shorten as "Section 9" is an on-hiatus counter-terrorist unit of JGSDF. The unit is currently maintained and managed by SONARTac, and is under supervision of Colonel Miyoko Hikari.

Technically speaking, both units operate the same way, with the major difference being one is a national unit of a military branch, the other (Team Alpha) being a multi-nationality task force that is owned by a military corp division.

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.
