Cavalry tactics evolved over time in response to changing battlefield conditions and technology. In medieval Europe, knights clad in armor and wielding lances formed heavy cavalry units that were effective in close combat. As firearms and artillery became more prevalent, light cavalry units equipped with quick-moving horses and armed with sabers and carbines focused on hit-and-run tactics, harassing enemy forces, and scouting. Throughout history, various cultures have adapted their cavalry tactics to suit their particular needs and warfare styles.
