In the Civil War Reenacting community there is much discussion about authenticity. The degree of authenticity usually depends upon how close reproduction weapons, clothes, utensils, or uniforms are to what would have actually been used. The Third U.S. Regular Infantry Reenactors strive for authenticity but recognize that there are limits based on safety, cost, and availability.
As the demonstration battalion for the School of Brigade Drill at Jefferson Barracks, Missouri, the Third Infantry set the standards for appearance and drill for the entire Army in the 1840s. Today, the reenactors of the Third U.S. Regular Infantry strive to maintain that standard, and to achieve this goal we are constantly conducting research and revising our authenticity standards.
