It would seem to me that any reasonable amount of battlefield dust or smoke would diffuse any sort of laser to the point where it wouldn’t be effective at all. I’m sure that someone else could speak more authoritatively to this than I, but it just seems that the scatter would cause it to fail ...
Just hang disco balls from your tank
“It would seem to me that any reasonable amount of battlefield dust or smoke would diffuse ...”
Possibly a laser that powerful would vaporize dust/smoke/fog that was in it’s way - up to a certain point.
The shell of a car is very thin metal compared to the shell of an armored vehicle or tank.
In any event, I wouldn’t want that thing pointed at me.
