The soldier who died in Brecon while on a training exercise has been described as a 'beautiful grandson' and a 'superfit boy' by his family.
Josh Hoole, from Ecclefechan near Lockerbie in Scotland, was a member of The Rifles regiment.
The 26-year-old, who died on Tuesday, was conducting pre-course training for the Platoon Sergeants' Battle Course, which is described as "both mentally and physically demanding".
His grandfather John Craig said he was a 'beautiful grandson.'
"He was a dedicated soldier. He always wanted to be top dog. He was a superfit boy, he kept very fit."
"He visited me regularly, every chance he got. I took a bottle of whisky to him on the 12th of July for his 26th birthday."
