52 the target, maintained by appropriate sensors or sensor combinations; a sensor prioritization scheme (if required); and updates on the target’s window of vulnerability (if required). The process may also be run partially “in reverse” in cases where an emerging target is detected and engaged, but once it becomes clear it is a valid target, the sensors detecting it can examine recorded data to track the target back to its point of origin, such as a base camp, and thus potentially eliminate a wider threat or destroy more lucrative targets where only one might have been engaged without the benefit of newer tracking technologies. Such “point of origin hunting” has proven especially useful during stability and counterinsurgency operations such as those in Iraq. Target The target phase takes an identified, classified, located, and prioritized target; finalizes the desired effect and targeting solution against it; and obtains required approval to engage it. During this phase, COD personnel must review target restrictions, including collateral damage, ROE, LOAC, the NSL, the RTL, and FSCM. This phase accomplishes the equivalent of the “target validation” stage of the larger tasking cycle. It also accomplishes effects validation and weaponeering. COD personnel match available strike and sensor assets against desired effects, then formulate engagement options. They also submit assessment requirements. The selection of assets for a specific target will be based on many factors, such as the location and operational status of ISR and strike assets, support asset availability, weather conditions, ROE, target range, the number and type of missions in progress, available fuel and munitions, the adversary threat, and the accuracy of targeting acquisition data. This can be the lengthiest phase due to the large number of requirements that must be satisfied. In many cases, however, dynamic targeting can be accelerated if target phase actions can be initiated and/or completed in parallel with other phases. Engage In this phase, identification of the target as hostile is confirmed and engagement is ordered and transmitted to the pilot, aircrew, or operator of the selected weapon system. The engagement orders must be sent to, received by, and understood by the “shooter.” The engagement should be monitored and managed by the engaging component (for the air and space component, by the CAOC). The desired result of this phase is successful action against the target. Assess In this phase, predetermined assessment requests are measured against actions and desired effects on the target. ISR assets collect information about the engagement according to the collection plan (as modified during dynamic targeting) and attempt to determine whether desired effects and objectives were achieved. In cases of the most fleeting targets, quick assessment may be required in order to make expeditious re-
