6th Military Police Group (United States)
The 6th Military Police Group (or 6th MP Group) is a brigade-level federal law enforcement agency of the United States Department of the Army based in Joint Base Lewis–McChord and part of the United States Army Criminal Investigation Division (CID). Its primary function is to investigate felony crimes and serious violations of military law and the United States Code within the United States Army. The 6th Military Police Group's area of responsibility includes all of the United States west of the Mississippi River as well as Korea and Japan. Mission and purpose
The 6th Military Police Group's stated purpose is:

The special agents under the 6th MP Group do not fall under a given installation's regular chain of command, instead reporting directly to military police officers under the CID. The 6th MP Group agents investigate felonies including deaths but are often specialized; there are dedicated personnel including a dedicated drug suppression team, sexual assault investigators and civilian victim advocates, and a suicide task force. The 6th MP Group also conducts preventative outreach programs such as with domestic violence intervention. History
The 6th MP Group was constituted on March 9, 1965, and activated on March 25, 1965, at the Presidio of San Francisco in California and deactivated on March 29, 1972. The 6th MP Group was reactivated on October 16, 1994, at Fort Lewis in Washington. Elements of the 6th MP Group operated within Afghanistan as part of Operation Enduring Freedom. After the murder of Vanessa Guillén at an armory at Fort Hood in 2020, an investigation found that issues with drugs and violent crime had gone unaddressed under the 6th MP Group at Fort Hood, largely due to the CID agents stationed at Fort Hood being understaffed and largely comprising new, inexperienced apprentice agents. The investigation also raised concerns about CID leadership comprising regular MP officers who are unaccustomed to running a specialized investigative unit like CID. An investigation into Fort Hood's leadership resulted in fourteen commanders and other leaders being relieved or suspended, and led to the formation of a People First Task Force which aims to address issues at Fort Hood and overall Army policy. A separate investigation was also conducted to review the available resources of the 6th MP Group at Fort Hood as well as their policies and procedures. Subordinate units
