Exercise STEADFAST JUNO 10 (a Command Post [CPX]/Computer Assisted [CAX] exercise), which took place from 3 to 16 December 2010, trained expeditionary forces of the rotational NATO Response Force (NRF) and served as a final step in the training and evaluation of NRF 16.

Exercise STEADFAST JUNO 10 was an Allied Command Operations (ACO) sponsored NRF exercise designed to serve as a major step in the training and evaluation of NRF within its certification process. The aim of the exercise was to train, evaluate and certify NATO's Joint Operational Level headquarters together with their respective Component Commands for the sixteenth rotation of the NRF in 2011. The exercise was conducted simultaneously at six locations in Italy, Belgium, Norway and Turkey. Based on an austere expeditionary scenario, STEADFAST JUNO 10 was conducted on all three main levels: Strategic, Operational and Tactical for a NATO-led Crisis Response Operation to restore peace and security and to support reconstruction and humanitarian assistance. The main aim was to train and exercise NATO's Joint Force Command Naples (JFC Naples) as Joint HQ Main (JFC Naples currently leads NRF 16) as well as Allied Land Component Command (ALCC) Madrid for the Deployable Joint Staff Element (DJSE).

STEADFAST JUNO 10 was conducted by Admiral Samuel J. Locklear, III, U.S. Navy, Commander JFC Naples, and directed by Lieutenant General Wolfgang Korte, German Army, Commander Joint Warfare Centre.
