An energy weapon is a type of armament that uses directed energy, such as lasers, microwaves, or particle beams, to damage or incapacitate targets. Unlike traditional firearms that rely on projectiles, energy weapons emit energy in various forms to achieve their effects. They are often considered for military applications due to their potential for precision and reduced collateral damage. These weapons can vary in size and application, ranging from handheld devices to large installations. Research and development in energy weapons are ongoing, with organizations like the U.S. Department of Defense exploring their use for defense and offensive capabilities in modern warfare.
