A team of 13 soldiers from the Gloucestershire-based 1 Rifles battalion headed to Alaska this weekend to prepare for a dangerous attempt to climb North America's highest mountain.
The attempt, which is part of the Army's "adventurous training", will take as long as a month, and involve the 12 men and one woman attempting one of the hardest mountains to climb in the world.
"It's dangerous stuff," said an Army spokesman. "A climber was killed on the peak just weeks ago.
"The Beachley Barracks-based team have been training for the feat for months. It's a challenge which will put all of the fitness, navigation and team work skills which they've developed during years of soldiering to the ultimate test."
The team consists of soldiers from across the West, who are based at the barracks on the Gloucestershire side of the Wye, near Chepstow. They include Corporal Adam Richardson, from Swindon, and Lieutenant Jack Brown, from Cheltenham.
"The expedition is just one example of the adventurous training opportunities available to soldiers from 1 Rifles now that the battalion is no longer committed to the Afghanistan training and deployment," the spokesman added.
