British Army rugby league star Staff Sergeant Carrie Roberts said winning the Challenge Cup was "an amazing day".
SSgt Roberts scored an impressive try as her St. Helens team ran out comfortable winners against York City Knights in the final.
It means she is the first ever British soldier to ever win the Challenge Cup.
"Absolutely amazing. An amazing day," said SSgt Roberts.
"To score a try as well in the final of the Challenge Cup is just the icing on the cake."
The England international, who is looking to also impress at the World Cup later in the year, was asked if winning the Challenge Cup was the best moment of her career.
"100%," replied the Army player.
"Just because of the team that I did it with, the work that it took and the dedication to get there.
"The support I’ve had from the Army - being able to be off work and pursue this dream.
"Even just the staff at St. Helens. It's just a massive combined effort and that’s why it has been so special."
St. Helens were ruthless in attack with key player Amy Hardcastle taking the plaudits.
SSgt Roberts said: "She’s got loads of strike play as have most of the girls in the backline.
"We’ve been together quite a while now in training and working on that sort of strike play.
"We’ve kind of got a good connection between the centres and the halves as well.
"When we are playing and we’re flowing, we do it really well because we have trained a lot together."
Another play who impressed was Rachel Woosey, and SSgt Roberts says their mutual rugby union backgrounds have helped create an important partnership.
SSgt Roberts, who herself has been a key player for the Army's rugby union side, admitted she "love[s] playing" alongside Rachel Woosey.
"She’s got a rugby union background as well.
"Normally, she’s there for the offload."
