The second of two reservists who died during a selection exercise for the Territorial Army's SAS section at Brecon has been named.
Edward Maher died alongside Lance Corporal Craig Roberts after they collapsed in soaring temperatures while scaling Pen Y Fan in the Beacons on July 13.
A Ministry of Defence spokesman said, "Our thoughts are with his family and friends at this difficult time.Investigations are being carried out by Powys police and the army. We cannot comment any further until these investigations are complete."
Inquests of both reservists are due to be opened and adjourned this afternoon by Powys coroner Louise Hunt.
Although the full facts of the case will not be heard, the hearing will see the issuing of interim death certificates - allowing the bereaved families to begin funeral preparations.
It is also anticipated that a brief medical cause of death will be read into the public record for both cases.

When news of the deaths broke, tributes poured in for former teaching assistant L/Cpl Roberts, of Penrhyn Bay, near Llandudno.
The 24-year-old had reportedly served with the TA for more than five years, including tours of Iraq and Afghanistan.
