The problem is that the laser’s going to be super cumbersome and need a large charge of electricity to do any damage. Russia attacks surrounding power stations and then blows up the laser. It is a weapon of the future, but they need decades of working on amplification and such to make it portable and useable.
If it can’t shoot and scoot, it’s an expensive liability.
weapons like that mount their own power source ... you do NOT plug them into a wall receptacle ...
