List of deployments of the United States military forces overseas

Last updated

The Congressional Research Service (CRS) of the United States Congress [1] provides a list of "notable deployments of the United States military forces overseas" from 1798 through April 2023. [2] The CRS report is updated approximately annually. [3] [4]

Contents

The report explains, "The instances vary greatly in size of operation, [duration,] legal authorization, and significance. ... [I]nclusion in this list does not connote either the legality or the level of significance of the instance described. ... Because of differing judgments ..., other lists may include more or fewer instances." Footnote 1 of the report cites three sources of alternative lists, as well as a source for a discussion of the evolution of such lists. The data in this article are from version 41, published on June 7, 2023.
