The parents of a Royal Marine who died during a training exercise in Wales have paid tribute to their son.
Signaller Benjamin Poole, 26, was found dead on Monday after a "routine" exercise on the Brecon Beacons, the Ministry of Defence (MoD) said.
Marine Poole was the great grandson of Alexander Coutanche, Jersey's wartime bailiff.
A tribute from his Jersey parents and family said his "wit, fun and laughter... will live in us for ever".
The MoD said the cause of his death was unknown and it would not comment until a post-mortem had been completed.
His death is also being investigated by Dyfed-Powys Police and the Health and Safety Executive.
The family's tribute placed in a Jersey newspaper said: "Your wit, fun and laughter and our immense pride in you and all your accomplishments will live in us for ever. A wonderful light has gone out."
The MoD declined to comment on reports that Marine Poole had died following a punishment exercise for dropping litter.
An MoD spokesman said: "We are very saddened at the death of Marine Benjamin Poole and our thoughts are with his family at this difficult time.
"Marine Poole, a Royal Marines signaller, died while undertaking a routine UK Military training exercise on 28 July 2008.
"The cause of Marine Poole's death is not known at this time and it would be inappropriate to comment further."
