Here "Commandeur-Capitain til Søes" was placed below Schout-bij-nacht, above Captain and equal to Major. As of 2022, the rank is positioned below Commander and above Captain. It holds the grade of M401 within the Ministry of Defence's pay structure. Officially, the rank is translated as "Commander, Senior Grade".
