Following its recent commitments for the European Union in the Central African Republic in the framework of a training mission to the benefit of the local defense forces (EUTM RCA), Eurocorps is entering a preparation phase for a NATO operational certification. In 2020, Eurocorps will take on a standby phase for the Atlantic Alliance. By then, several exercises are foreseen to reach a high level of interoperability and meet the operational criteria set by NATO. This will be Eurocorps’ third standby phase for the NATO Response Force since 2006. Eurocorps hence demonstrates its capacity to ensure uninterrupted switching from EU to NATO operational commitments.
