In 1866, Congress passed legislation that created four all-African American U.S. Army units. The 9th and 10th Calvary and the 24th and 25th Infantry Regiments. These segregated troops served in the American West and played major roles in the Spanish-American War, both World Wars and the Korean War. This series prelude to an award-winning, multipart series of short documentary films was produced for the U.S. Army's Fort Huachuca and their Commanding General's Buffalo Soldier Days initiative. Tipping Point captured a small, but unforgettable part of the Buffalo Soldier legacy told through individual stories with historical imagery and lush moving illustrations.
