What is DD 5580/21 used for?

• A. Desk Journal
• B. Field Test Results
• C. Field Interview Card
• D. Evidence property custody receipt

Answer: (C)

The Field Interview Card is used to document in-the-field contacts with people encountered during patrols. It provides a concise, standardized way to capture essential details at the scene—who was involved, when and where the contact occurred, why the interview happened, descriptions of individuals or vehicles, what happened, and the disposition or outcome. This helps with situational awareness, supports later reports or investigations, and ensures information is preserved while it’s still fresh. It’s not meant for desk journal notes, which are broader and not tied to a specific interaction; not for recording field test results, which relate to tests or experiments; and not for evidence or property custody receipts, which track possession and transfer of physical items under chain-of-custody procedures.
