Assessment, Coordination, and Engagement

The Assessment, Coordination and Engagement (ACE) Branch provides cross-functional capabilities and expertise in concept development, doctrine and vision in support of the JAPCC’s activities and projects. The Branch’s Subject Matter Experts (SME) coordinate support to training and exercises, provide information and assessments available in the NATO Lessons Learned Process, as well as focused analysis of INTEL products. Additionally, they make sure that the newest developments in capabilities and defence planning related to NATO’s warfare development agenda are considered in the JAPCC’s program of work. The branch also supports planning and organization of the JAPCC’s main engagement events (the annual Joint Air & Space Power Conference, the Think Tank Forum and the Joint Air & Space Power Network Meeting) and manages the process to draft, layout and distribute the JAPCC’s publications.
