G4S's fortified 15-passenger transportation van was built under a contract with U.S. Immigration and Customs Enforcement (ICE) to transport removable aliens using these fortified vans. By driving aliens in custody to processing centers, or any other number of locations such as court appearances, hospitals, or prisons, G4S officers and these vans help ICE free up time and resources that can be put to better use, for example in tracking and apprehension.
