Which roles define the official deployment of GSDs in law enforcement?

Patrol, narcotics detection, search and rescue

Official deployment of German Shepherds in capacities governed by law enforcement and military organizations utilizes the breed's core attributes of intelligence and strength for critical tasks. Specifically, their roles within police agencies across continents such as the Americas, Asia, Europe, and Australia commonly encompass patrol duties that require physical presence and control, specialized scent work like narcotics detection, and critical rescue operations, including search and rescue (SAR) missions. These duties are distinct from the specialized assistance roles mentioned elsewhere.
