Fifth Order

From Memory Alpha, the free Star Trek reference.

The Cardassian Fifth Order was a military division of the Cardassian Guard.

The Fifth Order was known for their sophisticated military encryption codes, which used a recursive encryption algorithm, and was comparable to Elgol-red and Courier Code 5-9. Fifth Order Military Codes were among the miliary codes ruled out as belonging to the communique received at Deep Space 9 from the Gamma Quadrant. (DS9: "In Purgatory's Shadow")
