An obvious countermeasure would be to have the laser turn on only when the trigger is pulled. With a velocity of about a km per sec, the bullet won't give you much time to "remove yourself from the area".
So it'll be easy to recognise the important bad-guy because he'll be the one wearing the MILES gear, a second doesn't give you enough time to vacate the area, but you only have to move farther that the bullet has time to correct.
The likely target of this weapon is going to be some impoverished kid wiring up a dud mortar round as an IED by the side of the road.
Yeah right, the chain of command is going to authorize shooting a $50K bullet at a kid; also if somebody has to paint the target, then only a few dollars more gets you a live video feed so command can watch and control any engagements. I see this as being a replacement for the AGM-114, Hellfire missile on Predator and Reaper drones against soft, point targets. One problem we're having now is the bad-guys is using tactics that maximise collateral damage. these bullets will counter those tactics and give our drones he ability to engage many more targets.
