Crowds begin to gather in the morning light at the Women in Military Service for America Memorial, the ceremonial entrance to Arlington National Cemetery in Washington D.C. for the 20th anniversary ceremony, Oct. 21, 2017. Nearly 40 Oklahoma Air and Army National Guard women gathered with hundreds of active-duty, retired and reserve servicewomen from all branches of the military to celebrate the 20th anniversary of the dedication of the memorial to honor the women who came before them and celebrate the opportunities that are still to come.
