S.O.S Observer

Observers are the Stationers who formerly worked at the communication center at the Hizare DC Tower. After the outbreak, they have set up a new base at Medlife Tower, where they can relay orders to those on the field and keep tabs on where everyone is and what is needed. They also look over what surveillance footage they can and have access to at least a third of the station's systems, be their security or not.
Some brave few follow with Contamination Slayers on mission through various areas on the station and use their experience and tools to forcefully access systems that are either isolated or overtaken by the station A.I. That or help them put up additional surveillance and warning equipment.

Equipment

First-Aid Kit

Each Observer is given the First-Aid Kit to use on the field if they or someone else become wounded. A one-use gun pre-loaded with a single bullet has been packed down as well, to be used when there is no other salvation but eternal darkness.

Holo-Mobile

All Observers carry a Holo-Mobile: A handheld computer capable of projecting holograms. It can be used as both a databank, a high definition camera, and a communicator. It also functions as a short-range radar and a digital key.
Most will attach it to their person in some way or another.
