  the political, civil and military environments, and can disrupt illegal activities. Military operations in stability
  are characterized by indirectness rather than directness.
  TYPES
  4-276. Stability operations typically fall into ten broad and often overlapping types. For example, a
  force engaged in a peace operation may at the same time conduct arms control or a show of force to set
  the conditions for achieving an end state. This paragraph introduces stability operations. (See FM 3-0
  and FM 3-07 for more detailed information.) The LRSU can participate in any of the following
  operations in a stability environment:
  • Peace operations (POs).
  • Foreign internal defense (FID).
  • Humanitarian and civic assistance.
  • Foreign humanitarian assistance.
  • Security assistance.
  • Support to insurgencies.
  • Support to counterdrug operations.
  • Combating terrorism.
  • Noncombatant evacuation operations (NEO).
  • Arms control.
  • Show of force.
  PEACE OPERATIONS
  4-277. Peace operations (PO) support strategic and policy objectives and the diplomatic activities that
  implement them. POs include peacekeeping operations (PKOs), peace enforcement operations (PEOs),
  and support to diplomatic efforts to establish and maintain peace. Peace operations monitor and ease the
  implementation of agreements, such as a cease-fire or truce. They can also support diplomatic efforts to
  reach a long-term political settlement. They usually consist of observing, monitoring, or supervising and
  aiding the parties to a dispute. The mission of a peace operation is fluid, and is based on a review of
  METT-TC. LRSU activities supporting PKO include, among others—
  • R&S of a demilitarized zone.
  • Surveillance of confrontation areas.
  • Surveillance of cease-fire areas.
  • R&S of refugee camps.
  • Damage assessment.
  • Monitoring of chemical, biological, radiological, or nuclear activity.
  • R&S of smuggling routes.
  FOREIGN INTERNAL DEFENSE
  4-278. Foreign internal defense (FID) is participation by civilian and military agencies of a government
  in any action programs taken by another government to free and protect its society from subversion,
  lawlessness, and insurgency (FM 1-02). The main objective is to promote stability by helping a host
  nation establish and maintain institutions and facilities responsive to its people’s needs. Army forces in
  FID normally advise and assist host-nation forces conducting operations to increase their capabilities.
