Gashok the Hutt's criminal empire used several Perimeter Defence Stations around its land on the planet of Masr. They consisted of very basic walls and a few buildings for guards to live in. Often they held one or two light tanks which the guards would use to defend their station. These stations were often built near small settlments such as farms or villages which the guards could get supplies from, but were a few miles from them to avoid enemies finding the settlement. There were very few stations in many areas, but some areas had two per square mile.
