Timeline of United States military operations
This timeline of United States government military operations is based on the Committee on International Relations (now known as the U.S. House Committee on Foreign Affairs). Dates show the years in which U.S. government military units participated. Items in bold are the U.S. government wars most often considered to be major conflicts by historians and the general public. Note that instances where the U.S. government gave aid alone, with no military personnel involvement, are excluded, as are Central Intelligence Agency operations.
