Gunner Laura Moon has won the King's Troop Charity Race at the annual Combined Services Point to Point event at Larkhill Racecourse.
The King's Troop race is the day's main attraction and serves as an opportunity for military jockeys to show off their talent in a departure from their usual routine.
Forces jockeys compete in all of the races at Larkhill but this is the only all-military event.
Major Harry Wallace, Commanding Officer of the King's Troop, Royal Horse Artillery, said:
"It's a great showcase for the King's Troop, demonstrating just how versatile our horses are."
"Not only do they stand at Whitehall doing Queen's Life Guard [the guarding of Britain's official royal residences], they do their job as part of a mounted, ceremonial, saluting battery - but also they can do the Troop race as well."
"[We're] not only developing soldiers but the horses' confidence as well."
This year it was a close run race but Gunner Laura Moon, on Lagertha, was the first over the finish line to take her first victory in the event.
She said: "[It's] one of the main things in the calendar that everyone looks [forward] to.
"You want to be part of it. It's something different that no-one else gets to do. You want to say that you've done it."
For the jockeys, the race is a chance to test themselves over a tough course.
Gunner Rory Osborn, who was taking part for the first time, said:
"It was amazing. It was probably better than the gallop-out at Windsor, for when we do the Musical Drive. It was better than that - and that is hard to beat... Pure adrenaline."
Betting is not permitted on the King's Troops race.
Instead, all the money raised at the event goes to military charity SAAFA.
