What is the role indicated by the abbreviation SAC?

The abbreviation SAC stands for Special Agent in Charge. This title is used within law enforcement and intelligence agencies to designate a senior official responsible for overseeing specific operations, investigations, or units. The Special Agent in Charge manages the activities and personnel under their supervision and often serves as the principal advisor in matters related to criminal investigations and enforcement actions.

In the context of immigration enforcement and related activities, understanding the structure and roles, such as that of the Special Agent in Charge, is crucial for effective coordination and communication among different entities involved in maintaining national security and upholding immigration laws. The other options represent roles that, while relevant in different contexts, do not align with the established use of the acronym SAC in law enforcement and national security.
