On 1 January 2014, Feodosia Detached Battalion of Marines of the Ukrainian Navy began an operational stand-by in the NATO Response Force (NRF).

Engagement of military units of the Armed Forces of Ukraine in the NRF is a vivid example of successful development of NATO-Ukraine constructive partnership. It is also an efficient instrument for maintaining high level of combat readiness of Ukrainian Armed Forces, improving their interoperability and capabilities.

For reference: The NATO Response Force (NRF) is a highly ready and technologically advanced multinational NATO force, one of the core combat instruments of the Alliance. The NRF is made up of military units which are committed by allies and maintain high readiness in their home countries for a set period of time prepared to deploy into an operation theatre in case a decision to activate the NRF was made. Once the decision is made, the NRF is capable of deploying within five days.
