The Six Triple Eight on Netflix.
Based on the true story of the only Battalion (6888) of Black Women to serve overseas in WWII. Their orders were to sort millions of back log pieces of mail in 6 months. Mail was thought to be a morale boost for the soldiers.
Really well told story by Tyler Perry. Kerry Washington is great playing the part of Lt Col. Charity Adams who was the highest ranking African American woman in the army by the end of the war. Very impressive woman.
