In support of these policies, provost marshals and CID units must inform the
correct civilian police agency in certain cases. They must do so if, during a
criminal investigation, it is found that persons not subject to the UCMJ are
involved. Such involvement may be that they acted alone or jointly with Army

(1) To establish jurisdiction in cases that involve military, Federal,
or civilian interest thereby preventing duplication of investigative effort.
(2) To aid in planning and conducting investigations.
(3) To develop information not available from military sources.

certain agencies of certain offenses.

(7) To exchange information of mutual interest.
(8) To develop information of value to the commander in identifying and
correcting problem areas.
