Step van in the context of SWAT vehicle

A police armored vehicle, also referred to as a police rescue vehicle, armored rescue vehicle, tactical police vehicle, or SWAT vehicle, is a non-military armored vehicle used by police, primarily police tactical units and riot police, to respond to incidents that necessitate their use. They are most often in configurations similar to military light utility vehicles, infantry mobility vehicles, or armoured personnel carriers. They are generally designed to have armor that can sufficiently block high-caliber rounds, space to carry the unit's equipment, and sufficient passenger seating; some also allow for additional personnel to hang onto the side of the vehicle in transit.
