Through its multinational workforce, the Centre plays a critical role in preparing the Alliance for current and emerging security challenges.

The department we are supporting is responsible for the planning, preparation, and execution of operational and strategic-level exercises and training activities, while integrating warfare development, experimentation, concept development, and lessons learned into NATO's training programmes.
