  Defense Support of Civil Authorities
  ARFOR demonstrate the Army’s core competencies by combining offensive,
  defensive, and stability or DSCA tasks. The continuous, simultaneous combinations of
  offensive, defensive, and stability or DSCA tasks is known as decisive action. In
  DSCA, decisive action refers to how ARFOR combine DSCA tasks to support
  homeland security and, if required, DSCA tasks with offensive and defensive tasks to
  support homeland defense. The MEB is well suited to provide support to civil
  authorities because it has the most complete multifunctional staff of any Army brigade.
  The MEB also has the skills needed to provide command and control for units that are
  frequently needed by civil authorities. This appendix discusses the MEB support to
  DSCA.
