A Patriot Missile Weapon System managed by soldiers from the 3-43 Air Defense Artillery Battalion who are deployed from Fort Bliss, Texas., faces the blue sky at Al Udeid Air Base, Qatar, Jan. 22, 2014. The Patriot is the Army’s primary surface-to-air missile system and also functions as an anti-ballistic missile system, which protects the base from air and missile attacks. The Patriot is the only anti-ballistic missile system to have successfully engaged and destroyed a tactical ballistic missile in combat. (U.S Air Force photo/Senior Airman Jared Trimarchi)
