The family of one of three reservists who died on an SAS test march are "disappointed" by the decision to charge only two special forces soldiers with negligence, solicitors have said.

Lawyers for the relatives of Lance Corporal Craig Roberts, from Penrhyn Bay, said his loved ones felt "there are others that should be facing charges" in connection with the deaths.

L/Cpl Roberts and L/Cpl Edward Maher were pronounced dead on the Brecon Beacons after suffering heatstroke in July 2013.

Corporal James Dunsby died at Birmingham's Queen Elizabeth Hospital from multiple organ failure more than two weeks later.

At an inquest into their deaths in 2015, coroner Louise Hunt said parts of the planning and conduct of the march were inadequate or not fit for purpose.

Concluding the hearing in Solihull, West Midlands, Ms Hunt said inadequate supplies of water also contributed to one of the deaths.

All three men died as a result of a "failure to properly organise and manage" the march on July 13 2013, she added.

On Thursday, a spokesman for the Service Prosecuting Authority (SPA) confirmed charges of negligent performance of duty had been directed.

Two SAS soldiers, known only as 1A, who was the training officer in charge of the march, and 1B, a training warrant officer helping oversee the exercise, could face up to two years in prison and dismissal if convicted.

The SPA initially decided not to charge anyone over the deaths but the charges were directed after lawyers acting for some of the bereaved lodged a review.

Clare Stevens, a lawyer and director of Hilary Meredith Solicitors which represented L/Cpl Roberts' family at the inquest, said: "They're disappointed by this outcome and will continue to push for further recognition of what went wrong, those that are at fault, and also make sure changes happen."

She added: "They're disappointed that only these two (soldiers) are facing charges and they're very keen that there should be complete accountability for those higher up the chain of command that either had responsibility on the day or could have stopped it (the exercise)."

The law firm, which also represented Cpl Dunsby's father David at the inquest, and provided evidence at a subsequent parliamentary inquiry into military training exercises, said the Ministry of Defence had refused to accept corporate responsibility for deaths in training, exercises and selection events.

Hilary Meredith, the law firm's chairwoman and visiting professor of law and veterans' affairs at the University of Chester, said the MoD was "ignoring the will of a parliamentary inquiry and flying in the face of public opinion in the process.

"In any other corporate environment the employer, in this case the MoD, would take corporate responsibility and face a manslaughter charge," she said.

Ms Stevens added it should be the MoD in the dock and accused it of "looking for scapegoats".

She also said L/Cpl Roberts' family would "continue to fight".

"This has been a very slow process, which isn't great - neither for the families or the two soldiers who've been charged," Ms Stevens added.
