Weaponized migration

"Refugees as weapons" is a term used to describe a hostile government organizing, or threatening to organize, a sudden influx of refugees into another country or political entity with the intent of causing political disturbances in that entity. The responsible country (or sometimes a non-state actor) usually seeks to extract concessions from the targeted country and achieve some political, military, and/or economic objective.

The United States military U.S. Army Center for Army Lessons Learned released a handbook entitled "Commander's Guide to Support Operations Among Weaponized Displaced Persons, Refugees, and Evacuees". The handbook provides a basic overview of considerations and methods of reaction should CBRN warfare be executed using dislocated civilians.
