Joint Task Force Aztec Silence is a United States Department of Defense task force conducting anti-terrorism operations. In testimony before the Senate Armed Services Committee on 1 March 2005, then-United States European Command commander General James L. Jones said:
The 'assets' at Sigonella are a rotational squadron of United States Navy P-3 Orions. "In March 2004, P-3 aircraft from this squadron and reportedly operating from the southern Algerian base at Tamanrasset were deployed to monitor and gather intelligence on the movements of Algerian Salafist guerrillas [the GSPC, now known as the Al-Qaeda Organization in the Islamic Maghreb operating in Chad and to provide this intelligence to Chadian forces engaged in combat against the guerrillas." Aztec Silence has also involved Special Operations Command, Europe personnel deploying to Algiers.
