An “officer on duty” refers to a member of an organization, such as the military, police, or other services, who is currently working and responsible for specific tasks during their assigned shift. The term “duty officer” is often used interchangeably to denote an officer assigned to oversee operations during a particular period.
Military Context: In the military, a duty officer is assigned on a rotational basis, typically for 24 to 48 hours. They handle administrative tasks and address incidents requiring attention at any time, supplementing their regular duties. The outgoing duty officer briefs the incoming officer on relevant information before returning to their normal responsibilities.
Police Context: In police forces, the duty officer is responsible for overseeing operations during their shift. They manage patrols, respond to incidents, and ensure law and order within their jurisdiction. The specific duties can vary based on the department’s structure and the time of day.
Civil Services in South and Southeast Asia: In countries like India, the term “Officer on Special Duty” (OSD) refers to a civil service position between the ranks of secretary and undersecretary. This role often involves special assignments or projects, and the practice dates back to British colonial rule.
Overall, being “on duty” signifies that an officer is actively engaged in their professional responsibilities during a designated time frame.
