Headquartered in Ādaži, Latvia, the Division's command comprises personnel from Canada, France, Germany, Italy, Lithuania, Poland, Slovenia, Spain, Sweden and the United Kingdom, in addition to Denmark, Estonia and Latvia as the Division's framework nations. It was established in 2019, alongside the already existing Headquarters Multinational Division North East from Elbląg, Poland, in order to provide MNC NE with more robust C2 functions and greater situational awareness in the north of the Baltic Sea region. While summarizing his staff's work, Major General Flemming Mathiasen, Commander MND N, highlighted:
We succeeded in working together, combining efforts and maximising the effects of our actions.
GRLI23 took place across multiple locations in the region, e.g. Poland, Latvia, Lithuania and Germany. Of particular importance for the training output was the contribution by external stakeholders, including the German 1st Armoured and Polish 12th Mechanised Divisions. Their willingness to participate was an integral part of MNC NE’s ability to improve its operational capability and accomplish exercise and training objectives. By including so many Allies, GRLI23 was able to enhance NATO's interoperability based on the common use of doctrines, tactics, procedures and functional services.
Upon the completion of GRLI23, von Sandrart stated: "While this exercise is an important milestone, we have to make sure that we remain vigilant and continually improve our interoperability and readiness. Accordingly, this exercise is a milestone, not an endpoint."
