Inquests into the deaths of two Army reservists are due to be opened and adjourned this afternoon by Powys coroner Louise Hunt.
It is anticipated that a brief medical cause of death will be read into the public record for both cases.
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.
Emotional tributes have been paid to a third army reserve soldier who died from injuries sustained during SAS selection training.
One of two Army reservists killed in a military exercise in the Brecon Beacons on Saturday has been named as Lance Corporal Craig Roberts.
