A woman aiming to become the first female Navy SEAL officer quit about a week into the initial training, Task and Purpose reported Thursday.

The unidentified female candidate dropped out in early August during a three-week course in San Diego that began July 24. It was the first assessment of potential SEAL officers before they can be sent on to more grueling courses, according to the website, which cited "multiple Naval Special Warfare Command sources."

Two women, whose names were not released to protect their privacy, entered the famously difficult SEAL training program this summer more than a year and a half after the military allowed female troops to serve in combat roles.

The candidate who dropped out was enrolled in the Navy SEAL Officer Assessment and Selection program. If she had completed the program, she would have faced an officer selection panel and the Basic Underwater Demolition/SEAL program, or BUD/S, a six-month training course for the elite special operators.
