While keeping the peace in Iraq continues to vex American military planners, less-lethal, high-tech ways of controlling crowds continue to emerge.
In addition to the methods discussed here before, Jane's Defence Weekly looks at technologies in the pipeline like:
* The Clear A Space Device, which is similiar to a "flash-bang" grenade, but the effects last up to five minutes long. It would be used to disorient and remove personnel from an enclosed area, like a room or a ship's hold.
* The Running Gear Entanglement System, which would stop sea vessels by entangling the propellers.
* Drones carrying tear gas or malodorants.
* High-powered versions of the tasers currently used by police forces.
