The Artillery Battalion is in charge of organising the Four Days of the Yser.
In carrying out this mission, this battalion – some of whose barracks are located in Lombardsijde – is assisted by the 1st Carabiniers-1st Grenadiers Battalion, the 14th Medical Battalion, the military police and the military command of the Province of West Flanders.
The walk is organised in close cooperation with the municipality of Koksijde and the cities of Nieuwpoort, Diksmuide, Poperinge and Ypres.
