The Ministry of Defence has been ordered to make immediate changes following the deaths of three Army reservists who fell ill during SAS selection tests on the Brecon Beacons.
Craig John Roberts, 24, Edward John Maher, 31, and James Dunsby, 31, all died after becoming unwell in July on one of the hottest days of the year.
The Health and Safety Executive has now issued the MoD with a Crown Improvement Notice, which requires it to take immediate action to deal with potential risks arising from its military selection exercises.
A joint Health and Safety Executive (HSE) and police investigation into the circumstances surrounding the soldiers' deaths is continuing.
A third soldier who died following an SAS reservist training exercise in the Brecon Beacons suffered multiple organ failure, an inquest has heard.
Corporal James Dunsby died in hospital 17 days after collapsing on Pen Y Fan on 13th July. Lance Corporals Edward Maher and Craig Roberts also died in the incident.
The opening of an inquest into Cpl Dunsby's death at Aberdare Coroner's Court heard that the 31 year old was one of six soldiers to collapse on Pen Y Fan.
Coroner Louise Hunt said a post-mortem found his died of "multiple organ failure." The inquest was adjourned until September. A full inquest into the deaths of all three men will be held at a later date.
Tributes have been paid to 31-year-old Corporal James Dunsby, who died yesterday in hospital after falling ill during SAS selection training in the Brecon Beacons.
In a statement released through the Ministry of Defence, his family said he "adored the Army" and had the "most infectious enthusiasm for life".
He was the most loving and dependable husband, not to mention the most handsome of men of whom could not be more cherished.
James was and will remain a dearly loved, son, brother and husband. He had the uniquely wonderful ability to endear, enchant and captivate all who he met with his naughty sense of humour and highly intelligent wit.
With James as your friend you were ensured loyalty, strength, allegiance, protection and most of all a damn good laugh.
James adored the army and believed so passionately in his duty as a protector of Queen and country and of the realm.
James was so dearly loved by so many and will be sorely missed. Hurrah and Huzzah for James Dunsby; a greater man you could not meet.
We ask to be allowed to come to terms with our grief and loss of our beloved son and brother James.
