  Figure 5-4. Typical organization for cordon and search operations.
  Command Element
  5-66. An overall commander controls the unit conducting the cordon and search. He identifies the
  subordinate element leaders.
  Cordon Element
  5-67. This force must have enough combat power to cordon off the area. An effective cordon that both
  prevents the egress of individuals from the search area and prevents outside support to the search area,
  is critical to the success of the search effort. Based on the mission variables (METT-TC), two cordons are
  often established: an outer cordon to isolate the objective from outside reinforcements or disruptions,
  and an inner cordon to prevent individuals from leaving or communicating with someone outside the
  search area. Both cordon elements must maintain 360-degree security. UAS, scouts, attack reconnaissance
  aviation, or sniper teams should be considered by tactical units for use in observing the objective area
  for enemy both before and during the operation.
  Search/Assault Element
  5-68. The search element conducts the actual search operation. A search may orient on people, on
  materiel, on buildings, or on terrain. Normally, it is organized into special teams. The most basic search
  team is a two-person team consisting of one person who conducts the actual search while another person
  provides immediate security to the searcher. Establish discipline and standardized search SOPs to ensure
  searches are thorough, PIR-focused, and of minimal risk to Soldiers.
  5-69. All search elements must be prepared to handle male and female personnel, key equipment,
  hazardous materials (biohazards or other toxic elements), ordinance, and record key events. They must be
  trained to understand and on order execute information engagements, tactical site exploitation, detainee
  operations, and adjacent unit coordination. Search personnel must be trained to operate with HN security
  forces and within the established ROE. First aid and other medical training is critical. Soldiers must be
  proficient with signaling and marking devices as well as detection and recording equipment. Biometric
  and video/audio recording device proficiency is crucial in COIN search operations. Basic language training
  is essential to maintain effective searches and overall operational tempo.
  5-70. Typical search teams are organized in two- to three-Soldier teams. Female Soldiers are a proven
  combat multiplier during search operations, because few cultures tolerate males searching females. Search
  teams clear each room or area in accordance with FM 3-21.8. Units should not confuse entry methods
  and their levels of aggression with the requirement to respect the Host Nation’s people and homes.
  Typically, once a room is cleared, one team member provides security while the other(s) searches. All
  search element personnel are prepared to fight. Basic considerations for any search team include the
  following:
  • Detailed instructions including prohibited items such as weapons, chemicals, medicines,
  and machine tools.
