The Angolan Armed Forces, known by its Portuguese acronym FAA, are headed by a chief of staff who reports to the civilian minister of defense. There are three services--the army, navy, and air force. Total manpower is about 140,000. The army is by far the largest of the services with about 130,000 personnel. The navy numbers about 3,000 and operates several small patrol craft and barges. Air force personnel total about 7,000; its equipment includes Russian-manufactured fighters and transport planes. The "Casa Militar," or presidential guard, answers directly to the Office of the President and is separate from FAA command and control structures.
