The posts in the Command Group rotate between the three Framework Nations – Denmark, Germany and Poland. The Chief of Staff has three Deputies (DCOS) with the rank of Brigade General who support him and supervise the work in the subordinated Divisions.
Each "J" Division, which, in turn, is divided into a number of branches, is headed by "Assistant Chief of Staff" (ACOS) with the rank of Colonel or equivalent. The positions "Assistant Chief of Staff" and "Branch Chief" have been firmly allocated to the nations. Each Division has one goal: to advise the Commander in its field of expertise and to pursue the common objective – to fulfill the tasks assigned to the Headquarters.
The multinational character of all branches, including the smallest cells, makes this Headquarters unique. This structure ensures an extraordinary working environment that the Headquarters takes pride in.
Successful cooperation among officers and non-commissioned officers from as many as twenty two nations – Canada, Croatia, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Latvia, Lithuania, Netherlands, Poland, Romania, Slovakia, Slovenia, Spain, Republic of Türkiye, the United Kingdom and the United States – depends not only on understanding the challenges involved, but also on making the best out of the opportunities available.
In its peacetime structure, the Headquarters has 460 posts, including 60 civilian ones. This manning may be supplemented in case of any contingency.
