HQ ARRC is currently on stand-by for short-notice call-up and subsequent rapid deployment (5 days notice to move) in support of any potential NATO Response Force (NRF) mission that may develop during 2013.
An NRF is a coherent, high-readiness, joint, multinational force package of up to 25,000 troops that is technologically advanced, flexible, deployable, interoperable and sustainable. Its role is to act as a stand-alone military force available for rapid deployment as a collective-defence, crisis management or stabilization force, or to act as an initial entry force for a subsequent primary deployment.
The NRF traditionally comprises land, air and sea components provided by NATO members. An an NRF Land Component Command, or LCC, the ARRC will essentially be in command of all land combat troops on the ground during an NRF deployment.
