Training pushes soldiers 'to the edge of their endurance'

James Hopkinson, a former instructor at the Infantry Battle School in Brecon, has described the challenging conditions that the two soldiers who died would have been up against.

He said that military exercises in the Brecon Beacons were designed to push soldiers "to the edge of their endurance," but that measures would "undoubtedly" have been put in place to mitigate the effects of the hot weather.

He added that while the exact circumstances of the deaths remain unclear, such endurance training is needed to make the British Army "the best in the world".
