The information will be passed to the PM operations section, where it will be reviewed and forwarded to the G1 and the appropriate unit commander. See FM 19-20 for more information on criminal investigations. Two types of criminal investigations are performed by MP on the battlefield. Minor crimes are investigated by personnel from MP company operations sections. In a combat environment, few MP investigations of minor incidents will be required.
Major incidents involve death, serious bodily injury, war crimes, and major property loss or damage.
MP may verify such major incidents if operational priorities permit. The number of MP used for criminal investigation operations is directly related to the level and intensity of the battle. MPIs are assigned to MP companies in division and above to conduct criminal investigations. These MPIs are shown in their company's TOE by the skill identifier V5. Although each company has trained investigators, in combat these investigators may not be available at all times.
