While trying to research mp occupation units in ww2 I found this.
Mobility,Vigilance and Justice: The US Constabulary in Germany 1946-1953
by Kendall D. Gott. GWOT paper 11 at combat studies institute press.

I did not know but people were complaining that we won the war but were going to loose the peace in Germany much like Iraq!! So the Army developed new Constabulary units to rebuild the government. They even had their on unit patch. A big C on their uniform. It also includes the actual troopers hand book issued to them. Also a constabulary includes a MP-force,court, and jail all designed to work together. Also includes the rules to be enforced and how to do it. This is really a good stuff!!! Like they say history will get you if you forget. Dave can you help with the link it can be downloaded as a PDF file.

ps Jed read this please!!!
