Beta-5 Division

The Beta-5 Division is a United Nations Space Command Office of Naval Intelligence Section Three subcell. It is extremely secret, known by very few UNSC, or even ONI, personnel for that matter.

It is charged with the SPARTAN-III Program and is also known for its extreme decryption facilities. The helmet used by Beta-5 security forces is a shared asset between branches of the UNSC military and has also been adopted as a MJOLNIR variant.
