The background for its existence was changes in NATO's structure, in the European security situation and as a direct response to Denmark's involvement in UNPROFOR.

The purpose and design of the Brigade was to, in part or as a whole, to rapidly deploy in peacemaking, peacekeeping, humanity or similar missions under NATO, UN, OSCE or national supervision.

On 1 January 1996 the Brigade was also assigned to the NATO Allied Command Europe Rapid Reaction Corps and fell under the organisational control of 1 (UK) Armoured Division when required.

The DIB headquarters was located at Vordingborg barracks and made regularly exercises with 1 (UK) Armoured Division.

80% of the brigade consisted of volunteers who agreed to participate in up to two possible six-month international deployments during their four-year reserve commitment (originally this was only three years).
