Division intelligence support element

Overview
The division intelligence support element (DISE) is a small, forward intelligence support element of a split-based operation. As such, it is not a specific organization but rather an ad-hoc, tailored team uniquely configured to support the initial entry commander.

Once deployed, the DISE performs two major functions. First, it provides the initial entry commander a link from his forward command post back to an intelligence support base located outside the area of operations. This link provides the initial entry force J2/G2/S2 access to multisource Army and joint intelligence collection assets, processing systems, and databases. From these sources, the DISE can "pull" specified intelligence products. Second, the DISE provides the deployed commander timely, relevant, accurate, and continuous intelligence support that the commander needs to develop his intent, refine his concept of operations, and execute his mission.
