This documented briefing reflects the results of an Arroyo Center assessment of the implications of the war on terrorism for the United States Army. Much of the analysis was done shortly after operations in Afghanistan commenced in 2001. It is largely the product of a series of structured brainstorming sessions conducted by a group of RAND researchers at the time. Thus, it represents an initial look at possible implications and not the results of a long-term research effort.
However, in the intervening period some aspects of the work were further developed analytically. Also, where appropriate, reference to official U.S. policy documents bearing on the war on terrorism are now included. These documents did not exist when this work was originally done. Finally, in the context of the war on terrorism, the war with Iraq and subsequent occupation of the country are addressed where appropriate. This research was conducted in the Strategy, Doctrine, and Resources Program of RAND's Arroyo Center. The Arroyo Center is a federally funded research and development center sponsored by the United States Army.
