Instances of Use of United States Armed Forces Abroad, 1798 - 2004

This report lists hundreds of instances in which the United States has used its armed forces abroad in situations of military conflict or potential conflict or for other than normal peacetime purposes. It was compiled in part from various older lists and is intended primarily to provide a rough survey of past US military ventures abroad, without reference to the magnitude of the given instance noted. The listing often contains references, especially from 1980 forward, to continuing military deployments especially US military participation in multinational operations associated with NATO or the United Nations. Most of these post-1980 instances are summaries based on Presidential reports to Congress related to the War Powers Resolution. A comprehensive commentary regarding any of the instances listed is not undertaken here.
