Three soldiers have been charged with manslaughter following the death of a 22-year-old private at a barracks.
Hundreds of mourners attended Pte Williams' funeral
Gavin Williams collapsed and died on an "extremely hot day" at Lucknow Barracks in Tidworth, Wiltshire, the Crown Prosecution Service said.
Pte Williams, from Hengoed, Caerphilly, was serving with the Royal Welsh regiment when he died in July 2006.
Sgt Paul Blake, Sgt Russell Price and Cpl John Edwards are due before Salisbury magistrates on 1 August.
A Wiltshire Police spokesman said that, following the advice of the Crown Prosecution Service, five men who were arrested over the incident would not now be required to answer to police bail.
Hundreds of mourners attended the funeral of Pte Williams in Gelligaer, south Wales, in October last year.
As he was buried, soldiers from his regiment fired three shots in the air and a bugler played the Last Post.
