From Halopedia, the Halo wiki
Law enforcement agencies, often referred to as police and sometimes termed civilian security forces, are civilian organizations involved in the prevention of crime and apprehending criminals, maintaining public order, as well as other duties. These establishments are found on nearly all worlds within the Unified Earth Government's sphere of influence.
Many police forces utilize Special Weapons And Tactics teams for more dangerous situations.
In the early 26th-century during the Insurrection, the law enforcement in Promesa became reputed for corruption amidst a multi-faction conflict between them, various Insurrectionist factions, and UEG peacekeepers. The Colonial Administration Authority employed an organisation known as the CAA Marshals to serve as frontier sheriffs throughout the Outer Colonies.
Known police forces
They often use lighter weaponry than military personnel, though in some circumstances there is overlap.
During the Human-Covenant War, police forces were known to employ military weaponry for the purposes of assisting UNSC forces in the defense of their cities against the Covenant invasion. During the Battle of Mombasa, NMPD officers working alongside the Marine and ODST units deployed into the city employed M6C/SOCOM handguns, M90 shotguns, M7S SMGs and MA5C assault rifles among other weapons.
Law enforcement units were also known to employ the "Peacekeeper" variant of the Cyclops exoskeleton for riot control purposes, with NMPD employing its own specialised "Sector 12" variant equipped with a riot shield. Most units, however, would be destroyed in the war once pressed into active combat duty.
Law enforcement agencies often make use of land vehicles to be more mobile. Specialty sedans are sometimes elements of police forces.
Law enforcement agencies in some instances will use air vehicles as well. The D77C Pelican is manufactured for law enforcement needs, though the NMPD has their own offshoot of the design known as the D77C-NMPD Pelican.
