Military lasers seems _so_ science fiction. We've seen it done on the movie screens for so long, it _has_ to be real, right?

It seems to me like it'd be very difficult to transfer enough heat to be useful. Aiming the thing never really occurred to me as a problem. I mean, my camera has an "image stabilized" lens with neat-o gyros that shuffle the optics around to keep the image properly focused. In my simpleton's mind, I wonder why we can't use similar technology to put laser-light where we want it.
