The Sieza MDS guards a military checkpoint for the US forces base in the United Kingdom
A military checkpoint is a permanent feature where access by civilian visitors and vehicles is controlled by a military authority. One of the US forces bases in the United Kingdom receives dozens of visits a day at its checkpoint, and all cars are checked for unauthorized transport of people inside or out. The system they used so far did not work as the checkpoint guards expected. Detection of each vehicle lasted longer than 5 minutes and was unreliable with frequent jet flights over the object.
