Pretty frakkin' cool

Army Field-Testing "Judge Dredd" Super-Grenade-Launcher

What makes it super? Well, everything. Basically the idea is that the shooter can tell the gun at precisely what distance to air-burst the shell. So if a jihadi is hiding behind a corner, you tell the gun to set the charge off just as it passes his position, blowing it up at an angle from which he has no cover. Same deal if he's in a trench -- you blow it up just as it passes over his head.

It basically denies an enemy the advantage of cover.
