What does the acronym FID stand for?

The acronym FID stands for Foreign Internal Defense. This term is used in military and security contexts to describe the assistance provided by a nation to help another country maintain its internal security and stability. It encompasses a range of activities, including training and support for a host nation's security forces to combat internal threats, such as insurgencies or terrorism. This concept is vital in Security Force Assistance as it emphasizes the role of external support in enhancing the capacity and capability of foreign military and paramilitary forces to defend their country's sovereignty and maintain public order. By focusing on training, advising, and equipping local forces, FID aims to create self-sufficient defense mechanisms within the host nation, reducing the need for direct military intervention by external forces.
