The U.S. Cavalry

The U.S. Cavalry was a branch of the military responsible for mounted troops—soldiers on horses—primarily used from the 19th to early 20th centuries. They played key roles in exploring, defending borders, fighting in wars, and maintaining order in frontier areas. Cavalry units were skilled in reconnaissance, quick strikes, and supporting infantry, offering mobility and speed that wheeled or foot soldiers couldn’t match. Over time, advancements in technology led to the decline of horse-mounted units, replaced by mechanized forces like tanks and armored vehicles. The cavalry's legacy includes a rich history of frontier expansion and military innovation.
