'Lessons must be learned' call from tank blast soldier's widow
The widow of one of two soldiers killed in a tank blast on a live-firing range, after a key design flaw went undetected, has said "lessons must be learned" from the deadly incident.
Corporals Matthew Hatfield and Darren Neilson, both of the Royal Tank Regiment (RTR), died of their injuries after a "high pressure" gun breech blast and "ferocious" fire in their Challenger 2 at the Castlemartin firing ranges in Pembrokeshire, south-west Wales, on June 14 2017.
At an inquest on Tuesday, Louise Hunt, senior coroner for Birmingham and Solihull, concluded the "main cause" was that the gun could be fired when a key component - the bolt vent axial (BVA), which forms an air-tight seal to stop 3,000C hot gases escaping into the crew turret - was missing.
Ms Hunt said: "The main cause of this incident was the tank being able to fire without the BVA assembly being present.
"During production and manufacture of the gun, this hazard was not adequately considered or investigated and therefore the ability of the gun to fire without the BVA present went undetected."
After the inquest, Cpl Neilson's widow, Jemma Neilson, said health and safety should have been "world class" and called for immediate changes by the Ministry of Defence (MoD) and Army.
She said: "No soldier should ever be killed in training.
"Lessons must be learned, cultures must change and the MoD must accept failings and implement change immediately.
"An incident of this nature must never happen again."
The Army said it had already improved training, weapons drills, and procedures.
Mrs Neilson added that the coroner's findings had ruled out any suggestion that the two "highly professional" expert regimental gunnery instructors may have been, as one witness had told the hearing, "showing off" ahead of the incident.
Ms Hunt concluded there were "other issues which contributed to the incident", including a lack of written procedures for soldiers to follow when handling the BVA, handing over tanks to new crews, communication, and equipment drills.
There was no set system in place to check for the key piece of equipment - the BVA - and an unknown loophole in the tank's gunnery system meant it could be fired when not fitted.
The inquest also heard that four of tank's high-explosive ammunition bags, known as "bag charges", which propel the shell out of the tank's barrel, were "incorrectly stowed", and this was down to a culture within the armoured corps.
Ms Hunt concluded: "Failure to correctly stow charges caused a secondary explosion following failure of the breech block due to the absence of the BVA assembly, and the practice of unstowed charges was routine."
The coroner heard a succession of troopers give evidence that the charges were sometimes stored out of heat-proof storage bins within the turret, including an occasion when one was "on a soldier's lap".
Cpl Neilson, 31, from Preston, Lancashire, was the tank commander and was thrown from the turret during the blast, while Cpl Hatfield, 27, and a father of one, from Amesbury, Wiltshire, was loading ammunition.
Both men were taken to hospital but died of their injuries the following day.
Two other soldiers, Warrant Officer Stuart Lawson and Trooper Michael Warren, were also injured but survived.
Cpls Neilson and Hatfield, both highly-trained gunnery instructors with combat experience in Iraq and Afghanistan, were taking WO Lawson out for a "guest shoot" experience, to show how the tank performed when firing.
But the inquest heard that the RTR commanding officer, Lieutenant Colonel Simon Ridgway, was supposed to have written authorisation from a more senior officer for the guest shoot, as required by Army rules, but told the coroner he "had not appreciated that at the time".
He also "failed" to spot a culture of crews wrongly storing high-explosive charges in their turrets.
Asked if it was a failure of his leadership during his evidence, Lt Col Ridgway said: "I think I failed to identify it was happening.
"I'm not sure it's a failure of leadership."
A report to prevent future deaths with three recommendations has been sent to the Ministry of Defence and BAE Systems, which designed and manufactured the British Army's main battle tank.
Afterwards, Cpl Hatfield's fiancee, Jill McBride, speaking on behalf of the soldier's wife, Abigail Hatfield, from whom he was separated, said a "weight has been lifted".
Thanking the coroner, she added: "It was important to us to make sure the reputation of both Matthew and Darren was protected and remained true."
Colonel Jim Taylor, of the British Army, said it had already overhauled training but would look at "what further changes need to be made".
He added: "We are sincerely sorry for what has happened and we will do everything we can to ensure this never happens again."
