The MoD has published its response to the damning report on the deaths of James Dunsby from Trowbridge and 2 others.
Earlier this year a coroner ruled that neglect played a part in the deaths of the three Army reservists, who collapsed during a 16-mile SAS test march.
The coroner at the inquest into a soldier from Wiltshire who was one of three to die on an exercise in Wales has begun giving her verdict. Cpl James Dunsby from Trowbridge died from multiple organ failure and hyperthermia (overheating) on the SAS exercise in the Brecon Beacons on a hot day in July two years ago.
The Birmingham coroner Louise Hunt said the organisers of the exercise had failed to made dynamic risk assessments, gave inadequate briefings and left the reservist candidates confused as to where water would be.
The trainees were given no advice about water consumption and organisers identified the wrong hospital as being the closest for casualties. One commander admitted he did not know the day's weather forecast.
The MoD has described the deaths from heat exhaustion of three SAS reservists - including James Dunsby from Wiltshire - as "unacceptable".
