As part of these Assurance Measures, NATO's Air Policing mission is enhanced across two Implementation Areas. NATO members are authorized and encouraged to provide additional assets to the Alliance supplementing existing Baltic Air Policing capabilities in the northern Implementation Area and, in parallel, augmenting national Air Policing capabilities in the southern Implementation Area.
Since 2014, Baltic Air Policing has been continuously augmented as part of the Assurance Measures by a second detachment, based at Ämari, Estonia
. In the South, Romania's and Bulgaria's national Air Policing capabilities are and have been temporarily augmented by detachments from various Allied Air Forces. Whilst these nations are fully capable of conducting Air Policing operations on their own, aircraft and pilots of augmenting detachments can also be scrambled to conduct intercepts.
