Quick Summary

Jonathan Bevan, a former tank commander, is suing the Ministry of Defence for £500,000 after claiming his hearing was damaged while testing the Army's Ajax armoured vehicles. Bevan alleges that chronic tinnitus and mental health issues were caused by "acoustic shock" from headset alarms sounding every six to seven seconds during tests of the £6.3 billion fleet. His lawsuit challenges a previous dismissal by Judge Nigel Bird, arguing that his symptoms are directly linked to acoustic shock syndrome.

Story summary

Jonathan Bevan, a 46-year-old former tank commander, is suing the Ministry of Defence (MoD) for £500,000 after he claims his hearing was destroyed while testing the Army's new Ajax fleet. He suffered chronic tinnitus and mental health issues, which he attributes to 'acoustic shock' syndrome caused by repeated piercing alarms in his headset during tests. Bevan alleges that the emergency alarms sounded every six to seven seconds, leading to severe auditory damage. Initially dismissed by Judge Nigel Bird last April for lack of evidence linking acoustic shock syndrome to his symptoms, Bevan's case is now before the Court of Appeal, where his lawyers argue that Judge Bird's conclusion was incorrect. The Ajax fleet, which has been described as 'troubled,' costs an estimated £6.3 billion and its effectiveness is under scrutiny following a report by the Public Accounts Committee noting that armoured vehicles causing injury when operated outside rigid parameters are of little use on the modern battlefield.
