The challenge is a statewide community-led effort to register all eligible women veterans from the state of Maine for recognition on the women's memorial at Arlington National Cemetery.
The women's memorial was founded in 1997. It is the only major national memorial honoring all women who have defended America throughout history.
Organizers said they want to include every woman who has served, starting with the American Revolution through the present day.
"I know how important that history is and I also want to stress if you don't record it, it's lost. It's lost to time so I really want to encourage all Mainers to register and to help spread the word," said Sarah Sherman, director of strategic partnerships.
Organizers said the Maine Women Veterans Memorial Challenge aims to engage local communities throughout the state in a friendly competition to register every known Maine women veteran past or present.
Registration is free. It can be done online at womensmemorial.org or by requesting a paper form by calling Joy at 930-5640.
