What is the first step in the Intelligence Preparation of the Battlefield?

The first step in the Intelligence Preparation of the Battlefield (IPB) is to define the operational environment. This step establishes a common understanding of the battlespace, including where operations will be conducted and the factors that will influence those operations. Defining the operational environment involves analyzing the terrain, weather, and the socio-political aspects of the area, which collectively help to shape the intelligence efforts to follow.

It sets the foundation for the subsequent steps in the IPB process, as it dictates how the environment will impact both the friendly and enemy forces. By clearly defining the operational environment, military planners can better assess capabilities, vulnerabilities, and the dynamics that will affect operations, leading to more informed decision-making as they progress through the IPB. This clarity is crucial for effective mission planning and execution.
