For the first time, a female sailor has completed the US Navy training programme to become a Special Warfare Combatant-craft Crewman (SWCC).
Members of the elite US defence force group support Navy SEALs in high-risk warfare missions, and conduct their own classified military operations.
The sailor who completed the gruelling 37 weeks of training has not been named, in line with Pentagon policy.
The US military began allowing women to serve in combat roles in 2015.
