What are the four steps in the IPB process?

• A. Identify Threat; Define OE; Describe environment; Determine COAs
• B. Define the OE; Describe environmental effects on OE; Assess Risk; Determine Threat COAs
• C. Define the OE; Describe environmental effects on OE; Evaluate Threat; Determine Threat COAs
• D. Define the OE; Describe weather patterns; Evaluate Threat; Determine COAs

Answer: (C)

IPB builds the intelligence picture by moving through four linked steps: first define the operational environment to set the boundaries and key variables; then describe how that environment affects operations within that environment; next evaluate the threat’s capabilities and likely actions in light of those environmental effects; and finally determine threat courses of action that the enemy could pursue given the environment and capabilities. This sequence ensures planners understand how weather, terrain, civilian factors, and other environmental elements shape both sides’ options and risks, then translate that understanding into plausible enemy actions.

That’s why the option that lists defining the OE, describing environmental effects on the OE, evaluating the threat, and determining threat COAs is the best fit. Other options either omit environmental effects, insert non-IPB steps like risk assessment, or focus too narrowly on weather patterns rather than the full environmental context.
