Which officer is designated to operate the DFSG during an encounter?

• A. Backup officer
• B. Primary officer
• C. Subject
• D. Counselor

Answer: (B)

The key idea is clear responsibility during a high-stress encounter. The officer designated as the primary operator is the one trained and positioned to deploy the DFSG. This setup ensures consistent action, precise training, and accountability, since the primary officer is the person authorized to initiate and control the device's use according to policy and safety procedures. The backup officer, while ready to assist and take over if needed, supports rather than directly operates the DFSG. The subject is the person involved in the incident, not the operator, and a counselor is focused on crisis intervention and de-escalation, not weapon deployment.
