A British soldier who's taking part in the upcoming Invictus Games has spoken about how he'll compete as an archer - using his mouth.
Corporal Callum Nugent, who still serves in the Army, was injured playing rugby and has severe nerve damage and a loss of mobility in his right arm. He said:
"It's very fine [margins]. You can move your head to the wrong position - left or right by a millimetre - and it could be [a difference of] an inch, two inches on the target."
"It's quite a big difference... It's just making sure body position is the same every single time."
It comes with the start of this year's competition less than three weeks away.
The Games, which see 550 wounded, injured or sick forces personnel and veterans from 17 different nations battle it out for glory, will start on September 23 in Toronto, Canada.
The UK team's archers, meanwhile, have been training at Lilleshall National Sports Centre.
Hopefully mirroring conditions in Canada, their training is being held outside, with everyone involved making sure the athletes are hitting all their targets.
Archery is a very exacting sport, with the focus required one of the many reasons it's so popular with these athletes.
Hannah 'Poppy' Pawsey was medically discharged from the Royal Marines Band after years of marching caused chronic pain in her hips and back.
She said: "A lot of people use it [archery] as therapy... You have to be so focused on what you're doing that there are times where you can't think about the things that, when you step away from the line, take over your mind."
There will be 15 UK archers of all abilities aiming for glory in Toronto with the help of a top-end coaching team.
