Forces at different readiness levels
In order to provide flexibility for conducting the full range of missions, as well as describing the availability of Allied Forces to NATO commanders, HQs and forces can be further sub-divided into two types of forces reflecting readiness levels: High Readiness Forces (HRF) and Forces of Lower Readiness (FLR). Together, HRF and FLR form the Graduated Readiness Forces (GRF). Graduated Readiness Forces Headquarters (GRF HQs) provide these forces with the appropriate command and control.
HRF readiness should range from 0 to 90 days and include capabilities for an immediate response (from 0 to 30 days and in the framework of the NATO Response Force). FLR should be reported with readiness ranges from 91 to 180 days and normally used to sustain deployed HQs and forces.
Graduated Readiness Forces and HQs
The NFS includes packages of capabilities consisting of GRF HQs (joint, land, air and maritime), Special operations and other combat forces and appropriate supporting assets. The NATO Defence Planning Process ensures that capabilities are made available by the nations (either individually, multinationally or collectively) in the requested quantity as well as with the appropriate quality, including their state of readiness.
Joint GRF HQs capable of commanding joint operations of differing scales to provide deployable joint command and control capabilities alongside the capabilities within the NCS, including their Joint Logistic Support Group (JLSG) HQ. This Joint capabilities are currently provided on the basis of GRF (Land) HQs.
NATO's Combined Joint CBRN Defence Task Force (CJ-CBRND-TF) provides a high readiness combined joint CBRN deployable force in support of NRF or other NATO commands and missions.
Land deployable headquarters will be able to command and control assigned forces up to the corps-size level. The following High Readiness Forces (Land) Headquarters are available to NATO:
- The Allied Rapid Reaction Corps (ARRC) HQ in Gloucester, United Kingdom;
- The Rapid Deployable German-Netherlands Corps HQ in Munster, Germany;
- The NATO Rapid Deployable Corps-Italy HQ in Solbiate Olona;
- The NATO Rapid Deployable Corps-Greece HQ in Thessaloniki;
- The NATO Rapid Deployable Corps-Spain HQ in Valencia, Spain;
- The NATO Rapid Deployable Corps-Turkey HQ in Istanbul;
- The Rapid Reaction Corps-France HQ in Lille;
- The EUROCORPS HQ in Strasbourg, France, sponsored by Belgium, France, Germany, Luxembourg and Spain. EUROCORPS HQ has a different international military status and is available to NATO through a technical arrangement with Allied Command Operations (ACO).
- The Multinational Corps HQ North-East in Szczecin, Poland, sponsored by Denmark, Germany and Poland (in the process of increasing readiness as HRF).
- Multi-National Division Southeast (MND-SE) HQ in Bucharest, Romania.
- Multi-National Division Northeast (MN D-NE) HQ In Elblag, Poland.
Additionally, there is significant future growth for the Land Domain with Multi-National Division North (MND-N) in Riga, Latvia; and the Joint Sustainment and Enabling Command (JSEC) in Ulm, Germany. Both are approved and moving toward IOC and FOC over the next 1-3 years.
