AP reports that the US Army will decide later this year whether to begin producing the Spider "networked munition" -- ie landmine -- system.

Military officials say the system answers criticisms about traditional mines because they are designed to self-destruct after a set period of time.

But as Human Rights Watch has pointed out, "smart" mines may be preferable than mines that last for decades, but that's not to say they're an acceptable method of defence.

"Smart" mines will still pose risks for civilians, there will still be new mine victims, and the clearance task will be just as time-consuming and costly.
