Kevin Holt was the only one of the three former soldiers who also saw combat in Afghanistan. While in the army, he was given mental health treatment including a period of hospitalisation in 2007. The army makes judgements about who can handle weapons and go on tours based on medical, as well as physical fitness, but Kevin assured medics that he could cope and wanted to soldier on. During that tour, the trauma he experienced - including losing five members of his battalion in one attack - had a lasting impact on him, cutting short his dreams of an army career.
