This is the Women in Military Service for America Memorial at Arlington National Cemetery. The memorial and the exhibits and archives associated with it are dedicated to honoring all women who have served with or in support of the United States armed forces.
This is a photo I took from the back of the memorial, looking out at a section of the cemetery.
It’s hard to see because this photo was taken on a cheap film camera and then scanned to digital, but the very closest tombstone is that of a woman who served in World War II.
