Blind Veterans UK is entering a team into the Pace Sticking World Championships.
A team of three veterans are currently preparing for the tournament. Kevin Alderton explained why.
"It came about through a conversation with a fellow blind veteran. We were just saying about some of the things we missed since we left, and one of the things was actually drill."
They've been training in London with Drum Major Tony Taylor:
"I've had to rethink the way I'm teaching them, and try to explain and move their hands into the correct position."
The contest takes place at Sandhurst in May.
