A tactician is a person skilled in planning and executing strategies to achieve specific goals, often in competitive situations like military operations, sports, or business. They analyze various factors, anticipate opponents' moves, and make decisions that maximize their chances of success. In military contexts, tacticians develop battle plans that consider terrain, troop movements, and enemy capabilities. In sports, they devise game strategies to outsmart opponents. Famous tacticians include Sun Tzu, author of "The Art of War," and Bill Belichick, known for his strategic prowess in American football.
