During November 2017, I took part once more in ARRCADE FUSION, the annual training exercise of the Allied Rapid Reaction Corps. This year, the exercise took place at Imjin Barracks to test the corps-level warfighting capabilities of the ARRC. It brought together more than 1,500 troops from across 23 NATO nations.

The tempo was not quite as demanding as on previous occasions, but the pace did pick up every now and then. During my stay, I encountered a broad range of legal dilemmas, inlcuding questions relating to targeting, the treatment of prisoners of war, rules of engagement, internally displaced persons, international responsibility and various other problems concerning the means and methods of warfare. As always, it was a hugely rewarding experience – fun and educational in equal measure.

Below is a short video to give you a taster of the exercise.
