SONARTac

SONARTac (abbreviations for Special Operations and Anti-Reactionary Tactical Organization) is a military organization founded by Zero-X Foundations. The first arc of Project Zero-X took place here.

History and Developments
SONARTac was founded in Feb 2005 to combat rising tensions prior and during "The Great Tokyo Attack" in 2005, and was later adapted by Japanese Gorvernments' to approves as "Special Military Unit".

The organizations consists of 5 different units, each accompanying different tasks according to their ability. Each units have 4 smaller branches (dubbed seeds, signed as Alpha, Bravo, Delta and X-Ray, with X-Ray being the reserved team for QRF and always-on-call stand-by)

The whole team infrastructure were based on British's SAS 22nd Regiment, Germany's GSG-9, America's Navy SEAL and Marine Corps.

Callsigns and Designations
SONARTac's callsign follows the same rules as Standard Military Call Sign.

Unit Seeds + Unit Code + Team Order Code (1-6, with 1 being the leader of the team and 6 for the last person in the order). e.g: Alpha 2-1 means the personel is from seed Alpha, belong to Team 2, and is the leader of the team (1).
 * Team callsigns following this pattern:

Personels
As of the end of the 1st arc, employees' number are estimated more than 2000 (although the actual number is higher due to their activities outside the Country and within the facility)

Trivia

 * Alpha 2 (Unit 2) was the only team in the whole series to only have 3 members instead of 6 like all other teams.
 * In the original plans, Bravo was designated as the "highest ranking team". The ideas was then scrapped as it's may cause confusions.
