The OPNAV 5580/21 form serves as a field interview card, which is utilized by military police and security personnel to document information gathered during field interviews. This form is instrumental in recording details such as the interviewee's information, the location of the encounter, and the reasons for the interview. It helps law enforcement maintain accurate and consistent records of interactions, which can be crucial for follow-up investigations or assessments of safety and security.

While the other options represent important functions of military documentation and procedures, they do not pertain specifically to the purpose of the OPNAV 5580/21. Acknowledging military suspects' rights, documenting property custody, and authorizing search and seizure are handled by other forms and protocols within the military law enforcement or legal framework. This specificity highlights the focused role of the OPNAV 5580/21 as a practical tool for immediate use in field operations.
