Its missions included the defense of the Twelve Colonies from the Cylon threat, should they ever decide to return; and it conducted research and development into technologies that could improve the success in those missions.
The Armistice Officer's uniform was adorned with this patch.
Dr. Gaius Baltar was a consultant for the Ministry and worked on the development of the Command Navigation Program which became an integral part of much of the Colonial Fleet's systems. One of Baltar's lovers, a contractor at the Ministry, assisted him with the CNP's programming.
On the day of the Fall of the Twelve Colonies, this woman reveals to Baltar that she is a Cylon agent, sixth out of 12 humanoid models, and that with the access she gained through Baltar, she was able to penetrate extremely sensitive assets such as the Colonial Defense Mainframe. In the course of fixing over half of Baltar's CNP programming algorithms, she secretly added backdoors into the program that would cripple the bulk of the Colonial Fleet and expose the Twelve Colonies to Cylon attack.
During the attack, the captain of Colonial Heavy 798 established contact with Jack at the Ministry, whom Laura Roslin was barely able to debrief prior to 798's detection by the Cylons (TRS: "Miniseries").
- In the Miniseries, Roslin refers to a Ministry of Civil Defense. It is unknown if this is a synonym for the Ministry of Defense or a separate ministry akin to the American Department of Homeland Security.
- The patch's lower text, "Kobol HQ", is likely a continuity error based on early drafts of the Miniseries script, where Kobol itself was originally the single homeworld of the Twelve Colonies.
