Joint Functions III-25 mission with the fire and movement of friendly forces is not required. The JFC is responsible for the planning and synchronization of the overall interdiction effort in the assigned operational area. The JFACC normally is the supported commander for the JFC’s overall air interdiction effort, while JFLCCs and JFMCCs are supported commanders for interdiction in their AOs. (b) At the direction of appropriate authorities, forces engaged in homeland defense (HD) or defense support of civil authorities (DSCA) may perform interdiction against specific targets. For example, military forces also provide DSCA to US departments or agencies responsible for domestic law enforcement interdiction activities when requested and approved by SecDef or the President. These activities include actions to divert, disrupt, delay, intercept, board, detain, or destroy, as appropriate, suspect vessels, vehicles, aircraft, people, and cargo. Federal law and DOD policy impose limitations on the types of support that the US military may provide and what type of military mission (e.g., HD or DSCA) is being conducted. See DODD 5525.5, DOD Cooperation with Civilian Law Enforcement Officials, for more information on DSCA to domestic law enforcement interdiction activities. (c) Many elements of the joint force can conduct interdiction operations. Air, land, maritime, and SOF can conduct interdiction operations as part of their larger or overall mission. For example, naval expeditionary forces charged with seizing and securing a lodgment along a coast may include the interdiction of opposing land and maritime forces inside the amphibious objective area (AOA) as part of the overall amphibious plan. (d) JFCs may choose to employ interdiction as a principal means to achieve an objective (with other components supporting the component leading the interdiction effort). For example, one of the JFC’s objectives associated with the seize initiative phase of an operation might be to prevent the enemy’s navy from interfering with friendly force sea transit through a choke point in the operational area. The JFC might task the JFACC to accomplish this through an interdiction effort supported by SOF. Interdiction during warfighting is not limited to any particular region of the operational area, but generally is conducted forward of or at a distance from friendly surface forces. Likewise, military interdiction that supports HD is guided and restricted by domestic law to a greater extent than other interdiction. Joint interdiction can be planned to create tactical, operational-level, or strategic advantages for the joint force, with corresponding adverse effects on the enemy. Interdiction deep in the enemy’s rear area can have broad operational effects; however, deep interdiction may have a delayed effect on land, maritime, and selected SO. Interdiction closer to land, maritime, and joint SOF will have more immediate operational and tactical effects. Thus, JFCs vary the emphasis upon interdiction operations and surface maneuvers, depending on the strategic and operational situation confronting them. (e) Counter threat finance (CTF) incorporates efforts to interdict money that funds terrorism, illegal narcotics networks, weapons proliferation, espionage, and other activities that generate revenue through trafficking networks. Illicit finance networks represent a critical vulnerability of state and non-state adversaries threatening US national security. Employing CTF activities are the means to detect, counter, contain, disrupt, deter,
