  ARMY DEFENSE SUPPORT OF CIVIL AUTHORITIES TASKS
  6-5. The four core tasks in support of DSCA are—
  * Provide support for domestic disasters.
  * Provide support for domestic civilian law enforcement.
  * Provide support for domestic chemical, biological, radiological, or nuclear (known as CBRN)
  incidents.
  * Provide other designated domestic support.
  6-6. Within these primary tasks, Soldiers may perform various tasks such as firefighting, responding to
  civil disturbances, protecting critical infrastructure, or supporting federal and state counterdrug efforts.
  Each task may include personnel recovery as an implied risk. In the domestic environment, training and
  equipping only a few specialized personnel, such as aviators and special operations forces, does not
  significantly mitigate risk to the force.
  6-7. The response to any emergency always begins at the local level and grows from the bottom up, based
  on the National Response Framework and the National Incident Management System (discussed in
  ADP 3-28 and ADRP 3-28). Local first responders initiate response activities. If first responders cannot
  manage the situation, they request support through their civil authorities at the state level. Normally, the
  first Soldiers to provide response assistance are state National Guard forces. If additional forces are
  required, civil authorities may request additional support from the joint force headquarters state. As the
  need grows, so does the response. Eventually, National Guard units from several states through the
  emergency management assistance compact (known as EMAC), federalized National Guard units, Regular
  Army, and Army Reserve units may become partners in a coordinated response with federal, state, and
  local civilian partners. Army leadership coordinates the command and support relationships among these
  military and local, state, and national authorities based on the doctrine principles in ADP 3-28, ADRP 3-28,
  and JP 3-28.
  ACCOUNTABILITY CHALLENGES IN DEFENSE SUPPORT OF CIVIL AUTHORITIES
  6-8. Emergencies present significant personnel accountability challenges. Initially, Army leaders may
  lack critical details on the numbers, types, and precise locations of military responders in the AO. Soldiers
  potentially disperse across vast AOs in small teams. They may work in terrain encompassing multiple
  regional, state, and local jurisdictions. Wide dispersion, coupled with the effects of a disaster, increases the
  potential of isolation and complicates the personnel accountability challenge. This physical dispersion
  precludes immediate accessibility to mutual support and reduces the responsiveness of the forces if
  isolation incidents occur.
  6-9. Accountability is one of the immediate challenges, as leaders coordinate the differing civilian and
  military personnel accountability systems. Accountability proves difficult because of the desire to respond
  to the incident and immediately begin operations. Individuals, units, and their associated headquarters
  deploy, establish a presence in the operational area, and establish a chain of command. During initial
  deployment, the risk of isolation is greatest since Army and civilian leadership may still be coordinating
  who is working in what locations. The initial need to establish a personnel recovery structure with a
  doctrinal foundation includes wide-ranging personnel recovery guidance. This critical time requires fully
  staffed PRCSs and comprehensive ISG be provided to both military and civilian responders. Leaders must
  remind Soldiers that the greatest danger of isolation is during the initial deployment in DSCA.
  RESTRICTIONS ON THE USE OF FORCE
  6-10. Circumstances of DSCA may require the use of force. Commanders employ the minimum necessary
  force, in accordance with the rules for the use of force (known as RUF). These rules are similar to rules of
  engagement (known as ROE) used by forces in combat, but they are more limiting. The rules of
  engagement are permissive while the rules for the use of force are restrictive. Soldiers have the inherent
  right to self-defense. The rules for the use of force relate directly to individual Soldier skills. The command
  develops personnel recovery guidance and ISG concerning the use of force for each operation. The
  authorization to use lethal force remains with the President for federal military forces (operating under
