Who was the first female Marine?

Opha Mae Johnson is recognized as the first female Marine, enlisting in the United States Marine Corps on August 13, 1918. During World War I, the Marine Corps established the Marine Reserve (Females), allowing women to serve in non-combat roles to free up men for front-line duties. Johnson's enlistment marked the beginning of female participation in the Marine Corps, paving the way for future generations of women. Her significant contribution and pioneering role have established her as an important figure in military history.

The other individuals listed may have also made contributions to the Marine Corps, but they do not hold the historical significance of being the first female Marine, which is specifically associated with Opha Mae Johnson.
