| 英文摘要: | Recovering downed airmen is a critical task for the U.S. Air Force, which devotes considerable resources — including personnel, equipment, and training — to ensure that it can carry out this task. In light of the impending drawdown of forces and the pressure to reduce defense budgets, the Air Force has been reassessing its personnel recovery (PR) force structure, along with other organizational aspects. It asked RAND Project AIR FORCE to assist in this reassessment with an examination of the operational risk associated with Air Force PR. Specifically, the Air Force sought "to refine the metric used to assess PR's operational risk, [which] is the degree of likelihood of mission success." |
