The us department of defense believes that lasaer pointer weapons are highly accurate, responsive, fast and virtually immune to gravity, giving them an edge in dealing with threats such as swarm drones, rockets and artillery shells.
According to the us department of defense, laser weapons are ideal for destroying small, fast targets such as incoming rockets and artillery shells. They can disable ground vehicles and surface ships without killing people.
In addition, the current anti-missile system is more expensive than incoming missiles, making it impossible to defend against large-scale missile attacks, especially against low-cost swarm drones.
