Laser light can be dispersed or bent by atmosphere and whatever is suspended in it, like smoke or drizzle. Also, it needs precise targeting.

I can assume that laser links work wonderfully in outer space.

On land or sea, I can imagine using tactical smoke generators to disrupt laser links and visual navigation, giving an advantage to to systems that use e.g. microwaves for "vision", and radio channels for communication.

Also, why are you afraid of this development?
