Specialized preventive and detective groups, or [[Specialist investigation department|Specialist Investigation Department]]s, exist within many law enforcement organizations either for dealing with particular types of crime, such as traffic law enforcement, [[Police dog|K9/use of police dogs]], crash investigation, [[homicide]], or [[fraud]]; or for situations requiring specialized skills, such as [[Police diving|underwater search]], [[Police aviation|aviation]], [[Bomb disposal|explosive disposal]] ("bomb squad"), and [[Cybercrime|computer crime]].

Most larger jurisdictions employ [[police tactical unit]]s, specially selected and trained [[paramilitary]] units with specialized equipment, weapons, and training, for the purposes of dealing with particularly violent situations beyond the capability of a patrol officer response, including standoffs, counterterrorism, and rescue operations.

In [[counterinsurgency]]-type campaigns, select and specially trained units of police armed and equipped as [[light infantry]] have been designated as [[police field force]]s who perform [[paramilitary]]-type patrols and ambushes whilst retaining their police powers in areas that were highly dangerous.<ref>p.Davies, Bruce & McKay, Gary ''The Men Who Persevered:The AATTV'' 2005 Bruce & Unwin</ref>

Because their situational mandate typically focuses on removing innocent bystanders from dangerous people and dangerous situations, not violent resolution, they are often equipped with non-lethal tactical tools like [[chemical agents]], [[stun grenade]]s, and rubber bullets.
