This report summarizes selected congressional roll call votes related to instances in which U.S. Armed Forces have been sent abroad in potentially hostile situations. These votes reflect the type of congressional actions that observers maintain bear directly on issues affecting policy and the funding of troops abroad, often in the context of the War Powers Resolution, continued presence or withdrawal of troops, and the "use of force." The cases of Lebanon (1982-1983), Grenada (1983), Panama (1989), the Persian Gulf War (1990-1991), Somalia (1992-1995), Haiti (1993-1996), Bosnia (1992-1998), Kosovo (1999), the terrorist attack against the United States (2001) (including the use of U.S. Armed Forces in Afghanistan), and the use of U.S. Armed Forces against Iraq (2002-2003) and Iraq and Afghanistan (2001-Present) are examined, as are the revolution in Libya and its aftermath, the uprising and war in Syria, and military action against the self-proclaimed Islamic State (IS a.k.a, ISIS/ISIL). The roll call votes that are available online (since 1990 in the House and 1989 in the Senate) are hyperlinked in the text.
