It includes forewarning of enemy actions or intentions; the imminence of hostilities; insurgency; nuclear or non-nuclear attack on the United States, its overseas forces, or allied and/or coalition nations; hostile reactions to US reconnaissance activities; terrorists attacks; and other similar events. (¶2-19) |
| *indicator | (Army) Positive or negative evidence of threat activity or any characteristic of the AO which points toward threat vulnerabilities or the adoption or rejection by the threat of a particular capability, or which may influence the commander's selection of a COA.

| *intelligence | A line that designates the boundary between AOIRs. The G2/S2 |
| coordination line | establishes ICLs to facilitate coordination between higher, lateral, and subordinate units; coordinates with the G3/S3 to direct subordinates to track enemy units and HPTs in their areas; and hands over intelligence responsibility for areas of the battlefield. The establishment of ICLs ensures that there are no gaps in the collection effort; that all echelons are aware of the location, mis-sion, and capabilities of other assets; facilitates asset cueing, and provides timely exchange of information between assets. The G2/S2 keeps abreast of collection activities in progress (all echelons) and battlefield developments through the ICLs. (¶3-13) |
| intelligence discipline | (joint) A well-defined area of intelligence collection, processing, exploitation, and reporting using a specific category of technical or human resources.

| INTREP | intelligence report |
| INTSUM | intelligence summary |
| *intelligence | (Army) Those requirements generated from the staff's IRs |
| requirements | regarding the enemy and environment that are not a part of the CCIR (PIR and FFIR). Intelligence requirements require collection and can pro-vide answers in order to identify indicators of enemy actions or intent, which reduce the uncertainties associated with an operation. Significant changes (i.e., branches and sequels) with an operation usually lead to changes in intelligence requirements. (¶2-7) |
| *intelligence running | The intelligence running estimate is a continuous flow and pre- |
| estimate | sentation of relevant information and predictive intelligence that, when combined with the other staff running estimates, enable the decisionmaker's visualization and situational understanding of the AOI in order to achieve information superiority. The intelligence running estimate requires constant verification to support situational understanding of the current situation as well as predictive assessments for future operations. (¶5-30) |
| *intelligence | The task that ensures ISR operations are linked to the comman- |
| synchronization | der's requirements and respond in time to influence decisions and operations.

(¶1-24) |
| *intelligence | The plan the intelligence officer uses, with staff input, to synchro- |
