"The Alcatra League 1 is the first prison vehicle of its kind to be designed since 2045. Supplied to prisons both on Earth and the prison planets of Solart and Alcatra,. the League 1 is used in preventing the escape of convicts. As soon as the alarm is sounded, signalling a breakout, the League 1 goes into operation scanning the district. It cordons off vast areas by producing a force field enclosing the area. By the use of video radar anyone inside the force field can be instantly detected."
