the jurisdictions primary 911 EMS, fire and rescue service. ESUs also provide tactical emergency medical support, rescue of confined space victims, wildland/urban interface initial fire suppression, underwater rescue/recovery, high angle rope rescue, wildland search & rescue (SAR), auto accidents victim rescue, building collapses. In rural areas, ESUs perform suppression of wildland forest, brush and grass fires that occur, cliff and mountain search and rescue, underwater search and rescue, swift water and flood rescue operations. The key rationale for the integration of the functions is that many rural and remote communities do not have dedicated staffing, resources and infrastructure to sustain immediate 24/7 emergency response. A local ESU may exist to mainly provide emergency training such as CPR/AED, first aid, 1st responder, etc. to citizens, communities, OSHA work site and to marine/boating. This mobile training capability uses a light-duty emergency vehicle that is fully equipped with a basic life support (BLS) responder medical, wildland/urban interface firefighting system, powered hydraulic and air bag rescue systems, self-contained breathing apparatus and protective fire gear and other equipment and, when requested, can support the local emergency response system as a rapid intervention vehicle. A state or local public health Emergency Services Unit manages the Department’s emergency supplies, supporting technologies used during disasters, and helps fulfill the National and state Emergency Support Function (ESF) #8 Health & Medical Services and ESF #6 Mass Care & Sheltering needs of community citizens during a major emergency or disaster. Local chapters of the American Red Cross often maintain an Emergency Services Unit to provide disaster relief assistance to individuals and families affected by local disasters at fires and local disaster shelters as well as mobile emergency response vehicles (ERV)/ mobile canteens. Scores of our Nation's hospitals and medical centers use Emergency Services Unit to denote their specific organizational section that encompasses their emergency department (ED), Hospital Emergency Incident Management System (HEICS)-Emergency Coordination Center (ECC) and/or their "First Receiver" outside patient decontamination system, and sometimes includes a hospital operated emergency medical service (EMS) paramedic ambulance program. An Emergency Services Unit can also often denote a government or non-government entity emergency mental health or family crisis intervention team. Criticism Critics claim that the increasing number of ESU and SWAT indicates that the police in the United States are becoming increasingly "militarized". Among the critics is journalist and political analyst at the Cato Institute, Radley Balko, who has written several books and
