Barnett linked to a Small Wars Journal article on the need for Expeditionary Police.

Here is what I jotted down when I read (limited Internet Access has reduced my postings):

• US Constabulary Service
• Office of the Justice Department (or future Department of Peace) for International Deployment
• Separate Uniformed Service
• Runs international police academies and schools
• Runs exchange program
• Law Enforcement Officer Training Corps – like ROTC but going to the Constabulary or other US service for 6 years
• Civilian rules, not UCMJ.
• Includes a police core cadre of permanent employees and local/state police on 1 to 3 year exchange programs
• Contracts with state/city/county police forces, Private Security Companies, and Foreign Governments, in exchange for money and other services.
• The cadre core consists of organizers, logistics, managers, and support and maybe has 10% to 20% of the maximum deployable folks (the first people in maybe).
• The size of could grow and shrink because it contracts out for most of its workforce (police and/or security are what hey normally do).
• Has police/security mission
• Has a foreign advisory/training

Here is a United States Constabulary post-WW2.
