Timeline of United States military operations

Note that instances where the U.S. government gave aid alone, with no military personnel involvement, are excluded, as are Central Intelligence Agency operations. In domestic peacetime disputes such as riots and labor issues, only operations undertaken by active duty personnel (also called "federal troops" or "U.S. military") are depicted in this article; state defense forces and the National Guard) are not included, as they are not fully integrated into the U.S. Armed Forces even if they are federalized for duty within the United States itself.
