4-198. Information collection is a task of the intelligence warfighting function. In operations outside the United States, the intelligence warfighting function supports the exercise of command and control. As a function, intelligence facilitates situational understanding and supports decision making. The intelligence process supports the operations process through understanding the commander's information requirements, analyzing information from all sources, and conducting operations to develop the situation. The Army synchronizes its intelligence efforts with unified action partners to achieve unity of effort and to meet the commander's intent. In DSCA, the intelligence process normally used by Army staffs and units performing other decisive action operations (offensive, defensive, or stability) must be modified. There are four steps in this process (plan, collect, produce, and disseminate); and two continuing activities that occur across all four steps (analysis and assessment). Commanders drive this process. In DSCA, commanders determine their priorities for information collection, which the battalion or brigade intelligence officer (S-2) or assistant chief of staff, intelligence (G-2) satisfies.
