Tactics
UW is asymmetric warfare, which attempts to meet a conventional force under conditions that optimize the UW force's strengths; UW forces avoid combat when conditions are unfavorable to them.
Since UW and other special operations may precede operations by other military components (e.g., regular ground forces, air and missile attacks, etc.), friendly fire is a serious concern, since the special operation may be highly classified, such that the other components are not aware of the UW operation or its location. Deconfliction is the military term for avoiding fratricide, and it is the responsibility of the JSOTF commander, who must balance operations security (OPSEC) against the need for other components to know where they may operate freely.
The basic mechanism for deconfliction is establishing a Joint Special Operations Area (JSOA), defined by the overall joint force commander (JFC).
While establishment of a designated JSOA for SOF to conduct independent operations assists in the ease of control of SO and the prevention of fratricide, the JFC should always evaluate the value of isolating SOF against the greater benefit of integrating SOF into the overall campaign plan
Interdiction is the basic UW combat activity, which uses a variety of tactics to "drain the hostile power's morale and resources, disrupt its administration, and maintain the civilian population's morale and will to resist." UW attacks should be unpredictable, but widely dispersed and occasionally against a target previously struck, so the enemy must disperse his forces. Even in a guerrilla context, the dispersion of hostile forces may become so great that the guerrillas can temporarily gain a local superiority of force.
No target should be attacked without a specific reason for doing so; the selected targets should be part of neutralizing a system of targets. For example, if it is known that the enemy has limited supplies of fuel, attacks against tanker trucks, pipelines, refineries, and storage farms all contribute to damaging his petroleum, oil and lubricants (POL) system. If POL is deemed the critical target system, other attacks support the attacks on POL. If an attack on a barracks will draw away soldiers that otherwise might guard POL resources, such an attack is both diversionary and supportive of the main attack on a critical resource.
