NATO missions are operations conducted by the North Atlantic Treaty Organization to ensure collective defense and security among its member countries. These missions can include military interventions, crisis management, and cooperative security efforts, often in response to threats or conflicts that affect regional stability. In addition to military operations, NATO also engages in training and support missions to help partner nations build their defense capabilities. This includes initiatives like NATO's Partnership for Peace, which fosters collaboration with non-member countries, enhancing security and promoting democratic values across Europe and beyond.
