  SUPPORT TO COUNTERDRUG OPERATIONS
  4-286. Military efforts support law enforcement agencies (LEAs), other US agencies, state
  governments, and foreign governments. The goal of counterdrug operations is to stop the flow of illegal
  drugs at the source, in transit, and during distribution.
  • DOD may provide training, assistance, equipment, and facilities as long as doing so does not
  affect US military readiness.
  • The Posse Comitatus Act applies only to federalized forces, and only within the US.
  For example, federal military forces may not search US civilians, arrest US civilians, or
  conduct any related law-enforcement activity involving US civilians.
  • Title 10, United States Code, Sections 371-378, gives military forces the authority to assist
  civilian LEAs.
  • DOD may pass information collected during normal operations to law-enforcement agencies.
  • Military efforts support and complement--not replace--the counterdrug efforts of other entities.
  (These entities can include US agencies, states, and cooperating foreign governments.) The
  Army can support any or all phases of a combined and synchronized effort to attack the flow of
  illegal drugs at the source, in transit, and during distribution. In counterdrug operations, LRS
  normally supports law-enforcement agencies. LRSU activities supporting counterdrug
  operations include but are limited to—
  — R&S of shipment facilities.
  — R&S of shipment routes.
  — R&S of marijuana, cocoa, and poppy fields.
  — Surveillance of narcotics traffickers.
  — Surveillance of air and vehicle traffic.
