"It is with deep sadness that I can confirm the death of a soldier from the Royal Tank Regiment who died as a result of injuries sustained in an incident at Castlemartin Ranges," veterans minister Tobias Ellwood said in a statement released by the defence ministry yesterday.
The minister later confirmed the death of a second soldier at 9:30 pm (local time) on Thursday.
"Our thoughts are with his family and friends at this sad time," he said in a statement.
"The safety of our personnel is our absolute priority and a full investigation is underway to understand the details of this tragic incident," he said.
The death comes five years after 21-year-old soldier Michael Maguire was killed at Castlemartin when he was shot in the head after live machine gun fire was wrongly directed towards the safe haven he was in.
A 2013 inquest into Maguire's death found that he had been unlawfully killed.
