The LE battalions will be a force multiplier to the operating forces forward deployed by assisting in an array of missions from law enforcement, route regulation, humanitarian assistance, nonlethal weapons training, and military working dog employment. Marine Corps Bulletin 5400, released in September 2011, called for the reactivation of the 1st, 2nd, 3rd, and 4th Military Police Battalions, now designated as law enforcement battalions, in each Marine Expeditionary Force and Marine Forces Reserve. Three law enforcement battalions were activated in June 2012, with each battalion consisting of a headquarters and service company and two or more law enforcement companies. Each included "500 military police officers ["sic"] and dozens of dogs." (Note: As military units, each battalion contains only about 30 to 40 "officers," as the majority of the military police Marines are enlisted members and not officers. "Officers" as in any military organization, command the battalion and its organic companies and platoons and serve as staff officers in the battalion headquarters.)
