Chapter 23 Military  Assistance  To  Civil  Authorities

“DOD  has  traditionally  played  a  role  in  domestic  security  matters  only  when  absolutely  necessary.  DOD  wouldprovide  support  to  federal,  state  and  local  responders  when  civilian  capacities  become  overwhelmed.  For  instance,DOD  could  provide  transportation  or  medical  support  in  the  event  of  a  natural  or  man-made  disaster.  Also,  DODcould be called upon to provide additional security at national security special events (e.g., the Olympics). In the eventof multiple requests for DOD assets, domestic and international, the President would be the one to make the allocationdecisions,  using  the  coordinating  mechanisms  of  the  National  Security  Council  and  the  Homeland  Security  Council.”Donald  H.  Rumsfeld,  Secretary  of  Defense,  May  2002  testimony  before  the  Senate  Appropriations  Committee.Section  IIntroduction23–1.  Constitutional  and  policy  basis  for  military  assistance  to  civil  authorities  (MACA)a. The  basis  for  the  use  of  military  forces  to  assist  civil  authorities  stems  from  our  core  national  values.  Article  I,Section  8  of  the  Constitution  states,  “Congress  shall  have  power  ...  to  provide  for  calling  forth  the  Militia  to  executelaws of the Union, suppress Insurrections, and repel Invasions.” Article II, Section 8 states that the President shall “takethat  the  Laws  be  faithfully  executed.”b. The  military  serves  to  support  and  defend  the  nation;  this  responsibility  extends  to  military  responses  to  domesticemergencies  and  disasters.  From  our  nation’s  inception,  the  Army  has  provided  support  to  civilian  authorities  to  assistin times of crisis and need. Floods, riots, hurricanes, earthquakes, unknown substances, and forest fires are examples ofsituations  that  have  required  states  to  call  upon  the  National  Guard  or  request  support  from  federal  armed  forces.c. The  NSS  incorporates  the  aforementioned  national  values  and  sets  forth  three  key  national  interests-protect  thelives  and  safety  of  Americans,  maintain  the  sovereignty  of  the  United  States,  and  provide  for  the  prosperity  of  thenation  and  its  people.  Military  assistance  to  civil  authorities  (MACA)  in  times  of  need  contributes  significantly  tosatisfying these national security concerns. The strategy recognizes that America’s military may respond to a variety ofnational  needs  other  than  waging  war.  It  specifies  that:  “Terrorism,  WMD,  illegal  drug  trafficking,  and  other  threats  athome  or  abroad  may  exceed  the  capacity  of  other  agencies  and  require  the  use  of  military  forces.”d. The  National  Homeland  Security  Strategy  calls  for  the  military  to  support  civil  authorities  during  emergenciessuch  as  responding  to  an  attack  or  to  forest  fires,  floods,  tornadoes,  or  other  catastrophes,  as  well  as  to  assist  during...
