Hundreds of times in the last 210 years, the United States has deployed its military forces in conflicts abroad, although the U.S. has only formally declared war on eleven occasions.

A newly updated tabulation of those military deployments (pdf) — which do not include covert actions, disaster relief, or military training exercises — has recently been prepared by the Congressional Research Service. A copy of the updated report was obtained by Secrecy News.
