When moving detainees by foot vehicles should be positioned at the rear of the formation to provide which types of support?

When moving detainees by foot, vehicles positioned at the rear of the formation provide critical support in terms of security and rapid response. They ensure a secure perimeter, deterring potential threats from behind, and allow for quick evacuation or transport of detainees if necessary. Additionally, this positioning facilitates easier communication and coordination between foot personnel and vehicle operators. Overall, it enhances the safety and efficiency of the movement operation.
