The TADEN was a British experimental light machine gun firing the .280 in (7 mm) intermediate round. Alongside the bullpup EM-2 rifle design, it formed part of a proposal to reequip the British Army with new small arms which would use a round smaller than the .303 inch which was shown to be impractical for use in a modern assault rifle.

The TADEN used the action and gas system of the Bren but would fire from 250-round non-disintegrating metal-link belts rather than box magazines. The light machinegun model used a buttstock and trigger group like the Bren and the medium machine gun model used spade grips and a butterfly trigger like the Vickers.
The TADEN and EM-2 projects were discontinued when the United States Army refused to consider the .280 cartridge for the new NATO standard on the basis that it was less powerful than their .30-06 Springfield round (and, as others have suggested, the reluctance to adopt a round developed outside the USA).
It was decided that the TADEN and EM-2 could not realistically be reworked to take the new NATO round and alternatives were sought. The British Army reequipped with licence-built variants of the Belgian 7.62 mm FN MAG and FN FAL respectively. A belt fed derivative of the Bren gun had been considered for the GPMG role, but although not selected the Bren was kept on after adaptation to use the NATO round.
