The mobile stockade served as a transportable holding cell. It employed force fields created by a control box located outside the stockade to keep prisoners confined. The main force field manifested as a hemispherical dome projected onto the ground. This dome could be divided into two separate holding areas, or even further into four distinct sections. The control panel of the mobile stockade not only managed the main power supply and the force field divisions, but also allowed adjustment of the field's overall strength using a dial ranging from one to eleven. Without the proper key, the field's intensity could not be reduced below level two. Additional dials on the panel controlled the specific strength of each individual force field subdivision within the stockade.
Thrackan Sal-Solo and his soldiers from the Human League utilized a mobile stockade as a means of imprisoning Jacen, Jaina, and Anakin Solo, along with Chewbacca, Ebrihim, and Marcha, during the events of the First Corellian Insurrection. After secretly contacting the droid Q9-X2 using a concealed comlink, who then adjusted the field to the minimum possible setting without the master key, Anakin, along with the Solo twins, managed to gradually force their way through the barrier and break free.
