This experience made Valentine one of the only women in the world with Delta Force training. Despite her sex, Valentine was allowed to take part in the six-month intensive Operator Training Course, where she excelled in bomb disposal and lock picking and was known for her delicate though precise work, resilience, courage, and discernment amid the danger.
In the early 1990s, Valentine served in the United States Army and got the attention of recruiters for Delta Force, the nation's primary counter-terrorism unit. Valentine's father was French, and her mother was of Japanese descent (a 'Nikkei').
