William Isherwood, a former sergeant in the Irish Guards, sues the UK Ministry of Defence seeking £75,000, claiming his hearing was permanently damaged during Army training in Northern Ireland. He alleges that prolonged exposure to the noise of machine guns affected his hearing and that the condition persists. According to reports, Isherwood is bringing the claim as a former member of the Irish Guards, a regiment that guards the Royal Family. The Independent reports that he argues he was provided with inadequate or sub-standard ear protection during the relevant training period. The Daily Mail reports that he attributes the damage to the noise he experienced while training to serve in Northern Ireland and seeks compensation for lasting effects. The cases are reported as allegations by Isherwood; none of the outlets provide evidence of the outcome or a response from the Ministry of Defence in the excerpts shared. The lawsuit centers on whether the Ministry of Defence provided suitable hearing protection and whether his hearing damage is linked to machine-gun noise during his service.
