Capabilities Development Documents is the operational support requirement that

• A. Specifies training manuals
• B. Identifies capability shortfalls and possible migrations
• C. Sets budget
• D. Determines weapon procurement

Answer: (B)

Capabilities Development Documents focus on what’s missing in current capabilities and how those gaps could be bridged, including possible migration paths to reach the desired end state. In the JCIDS process, the document lays out operational shortfalls and evaluates options to close them, such as upgrading existing systems, integrating new components, or transitioning to alternative solutions. This emphasis on identifying gaps and outlining how to address them is why this option is the best fit. It isn’t about training manuals, it doesn’t set budgets, and it doesn’t by itself determine procurement decisions—the CDD guides the problem statement and potential approaches that inform later steps in capability development and acquisition.
