When moving detainees by foot what vehicles should be positioned at the rear of the formation?

When moving detainees by foot, it is essential to position support vehicles such as an ambulance and a tactical transport vehicle at the rear of the formation. This ensures that medical assistance is readily available if needed and provides a secure means to transport detainees in case of emergencies or complications. Additionally, a mobile command unit can be placed at the rear for coordination and oversight during the movement.
