United States Army Military Police (MP)

U. S. ARMY MILITARY POLICE - Military police (MP) are law enforcement agencies connected with, or part of, the military of a state.  The word can have different meanings in different countries, and may refer to:

• A section of the military responsible for policing the areas of responsibility of the armed forces (referred to as provosts) against all criminal activity by military or civilian personnel
• A section of the military responsible for policing in both the armed forces and in the civilian population (most gendarmeries, such as the French Gendarmerie)
• A section of the military solely responsible for policing the civilian population (such as the Romanian Gendarmerie or the Chilean Carabineros)
• The preventative police forces of each Brazilian state (Polícia Militar), responsible for policing the civilian population, which become auxiliary forces of the Brazilian Army in time of war
• The status of military police is usually prominently displayed on the helmet and/or on an armband, brassard, or arm or shoulder flash.  In the Second World War, the military police of the German Army still used a metal gorget as an emblem.
• Naval police members are sometimes called "masters-at-arms".
