She's been playing rugby since she was eight and now Sian Williams is Wales' first full-time professional female rugby player.
The Wales flanker has been awarded Elite Athlete status by her employers, the Royal Air Force, so she can play rugby professionally.
SAC Williams represented both the RAF and UK Armed Forces teams since she joined up in 2008 and currently serves as a Trade Group 18 Logistics (Mover) at RAF Brize Norton.
Watch Nick Hartley's report:
The Wrexham-born back row made her debut for Wales in 2011 against Scotland and has earned 20 full caps over the last two seasons and represented Wales Women at Sevens. She also plays regional rugby for Newport Gwent Dragons and in the premiership for Worcester.
