So basically, Boeing built a laser that can't power up fast enough to hit anything moving, and doesn't have a practicable targeting or tracking system anyway, plus lacks the range to stop any incoming threats before it's way too late, so they decided to shoot IEDs with it?
Obviously, an Avenger mount suggests a desire to have an anti-flyer application. Like the Israeli, Boeing probably ultimately hopes to intercept incoming dumb projectiles like mortar rounds or RPGs, and as an intermediate stage might succeed in diverting incoming missiles and LGBs, or harassing aircraft pilots. But since they only have the laser itself at this stage, without any means of aiming it, this fish-in-a-barrel application is as good as any for getting the sales pitch started.
Personally, I'd use the machine gun on that Avenger to get rid of a suspected IED, from a much safer distance.
