The laser they showed is obviously a CW one. The ones I think they will use will be high powered pulsed lasers.
I do know ( but can't say much), of a type I worked on, they "ganged" up 10 to experiment over 8yrs ago to shoot down airborne objects.
A lot has been developed since, I should imagine.

Am I the only one who can see a flaw in this cunning plan......?
Not entirely true with the above type.
