Council Security is a civilian agency within the Fleet that is responsible for security considerations of the civilians.
View on Council Security by the Warriors
It is evident that Council Security are viewed with disdain by Colonial Warriors (Greetings from Earth, Baltar's Escape). For instance, Colonel Tigh comments to Siress Tinia that Council Security couldn't stop an escape from the Orphan Ship (Baltar's Escape).
In addition, due to the color of their uniforms, they are also referred to as "Blackshirts."
Reese is a member of the organization.
- Continuity errors: In earlier episodes, such as "Lost Planet of the Gods, Part I", Blackshirts were merely referred to as Security officers. Two such officers attempt to discover who raided the officer's mess for supplies, until being thwarted by Colonel Tigh. Also, the Blackshirts seen in that episode do not have Galactica's patch; however, they seem to recognize Tigh's authority, while later episodes' Council Security officers challenge the authority of the military personnel.
