The NATO Response Force (NRF) was a high-readiness North Atlantic Treaty Organization (NATO) rapid multi-national deployment force comprising army, navy, air force, special forces, and special operations-capable forces units capable of being deployed quickly within short notice. The NRF comprises more than 500,000 troops. Its forces included units from several non-NATO member partners, including Ukraine (since 2014), and Georgia (since 2015).
The NRF was formed in June 2003 per endorsements at the 2002 Prague summit. Units assigned to the NRF were only used for disaster relief and security until February 2022, when it was activated for the first time in response to the Russian invasion of Ukraine. In 2024, it was replaced by Allied Reaction Force (ARF).
