Their very long range makes it difficult to find the source of a laser spot.

Singaporean soldier aiming a SAR 21 with laser sight. A laser sight is a device attached or integral to a firearm to aid target acquisition. Unlike optical and iron sights where the user looks through the device to aim at the target, laser sights project a beam onto the target, providing a visual reference point.
Light intensity 0.5 μW/cm 2; for example, a legal 5 mW laser pointer at 3,700 feet (1,100 m). FAA flight simulator showing veiling glare where it is hard to see through the light to the background scene. Light level 5.0 μW/cm 2; for example, a legal 5 mW laser pointer at 1,200 feet (370 m).
Laser pointers, even those sold for less than $20 online, can distract pilots or cause flash blindness — of particular danger during takeoff and landing, when many incidents are reported ...
Laser guidance is used by military to guide a missile or other projectile or vehicle to a target by means of a laser beam, either beam riding guidance or semi-active laser homing (SALH). [7] With this technique, a laser is kept pointed at the target and the laser radiation bounces off the target and is scattered in all directions (this is known ...
