Echo Station 3-T-8 was a defensive outpost on Thuban, manned by the Lyran Star Empire during the Battle of Thuban. It was manned by a hundred Stalkers in an attempt to stall an entire corps from the Interstellar Concordium Pacification Army.
The Berlusconi Institute for Excellence in Profiteering was built near where Echo Station 3-T-8 stood. (Star Trek: False Vacuum: "Structural Unemployment")
