Well it gets my attention! I have read about anti mortar tech based on radar which would reveal the source location, I don't know if this anti sniper system is strictly sound based, radar, microwave or what.

That's the AN/TPQ-36 and -37 *firefinder* counterbattery radars. They work.

They can pick up fired mortar rounds in flight, send out targeting data to a field artillery Fire Direction Control center, and have rounds fired and on the way before the mortar shells land.

The original versions with which I worked were based in 2½-ton trucks; the current systems can be moved by a standard HUMVEE. They're getting there. The Marines had one atop the barracks in Lebanon that was destroyed by the truck bomb, I believe, set up to coordinate naval gunfire in response to mortar or recon attacks against the Marine barracks...and so instead, the terrorists resorted to a truck bomb for their attack. *Firefinder*.

I hope it's gotten smaller and more portable in 20 years! (BTW, I rappeled off that roof in the winter/spring of 1983, and I didn't see anything like that then. The arty battles came later.)

Yeah, but is this equipment itself - bulletproof? The unit in the picture has good cover around the bottom, but what about the panel apparatus facing out? For this thing to work, something has to stick out. There's an Achilles heel somewhere...

I'm sure their locations are kept low-key, but if it can effectively return fire to a sniper's position, it too can be hit.

I also saw the shot-finder on the Discovery Channel program discussed above. It worked totally on acoustics. Deploying them in big city hoods is surely underway.
