Given the subject, I thought I'd throw in this older document; it's quite relevant, and is not referenced elsewhere on SWC:

Conference Report: Assessing the Role of Stability Police Units
On April 4-5 2005, the Center of Excellence for Stability Police Units (COESPU), the Institute for National Strategic Studies, the United States Army Peacekeeping and Stability Operations Institute (PKSOI), and the United States Institute of Peace (USIP) conducted a two-day assessment of “The Role of Stability Police Units” in peace operations at the National Defense University in Washington, DC.

The objectives for the workshop were to advance the development of common doctrine and operational procedures for all parties involved in the employment of Stability Police Units (SPU) and to assist CoESPU in establishing a network for discussion and harmonization of SPU doctrine. The focus of the discussion was on the international response to the riots in Kosovo on March 17-19, 2004, and the lessons that should be learned from that experience.

This report summarizes the panel discussions, with an emphasis on what doctrine currently specifies and how the response to the Kosovo riots might inform that doctrine. The report concludes by identifying gaps in current doctrine and discrepancies among the international organizations that field SPUs.
