In 1941, Frissell volunteered her photographic services to the American Red Cross.
Later she worked for the Eighth Army Air Force and became the official photographer of the Women's Army Corps.
On their behalf, she took thousands of images of nurses, front-line soldiers, WACs, African-American airmen, and orphaned children.

She traveled to the European front twice.
Her first picture to be published in Life magazine was of bombed out London in 1942.
Her moving photographs of military women and African American fighter pilots in the elite 332d Fighter Group (the "Tuskegee Airmen") were used to encourage public support for women and African Americans in the military.

During the War she produced a series of photographs of children that were used in an edition of Robert Louis Stevenson's much-published A child's garden of verses which were an early example of the successful use of photography in illustration of children's literature.
