Recovery of personnel is a joint responsibility which embraces a wide range of situations requiring different levels of responses.
Member nations provide NATO with the personnel and assets necessary to carry out NATO operations. In its turn, NATO must ensure there are means available to recover personnel under its responsibility who have become isolated. In the same vein, troop contributing nations must ensure their personnel have been appropriately trained and equipped to assist in their own recovery.
NATO has the responsibility of establishing an architecture capable of recovering the personnel who have become isolated while participating in NATO operations. This document provides the fundamental principles for the recovery of personnel in a hostile environment, during North Atlantic Council approved NATO operations, taking into account national responsibilities and considerations.
