The Military Security Service (or MSS) was a plainclothed Terran Confederacy military investigative unit. They had an intimidating reputation among the soldiers.
MSS members were present on Turaxis II during the Guild Wars, as they hunted for Confederate Old Family heir Ark Bennet. While they did discover him, Bennett was able to convince the agents to keep him in the Confederate Marine Corps.
