The Directorate of Military Intelligence (MI) provides intelligence to the Army, while the other main branches are served by Naval Intelligence and Air Intelligence. The intelligence services in each branch are tasked with providing intelligence on foreign operations, performing counterintelligence operations, and identifying and eliminating sleeper cells, foreign agents and other anti-Pakistani elements within Pakistan. Additional functions involve monitoring high-level military and political leaders and safe-guarding critical military and non-military facilities. The director-generals of each intelligence branch are usually two-star officers.
