From Nextgov.com: Insurgents years ago obtained U.S. systems used to stop IEDs, report says
The devices might have been sent to Iran to develop countermeasures that block jamming signals that prevent the detonation of roadside bombs, according to an Army document.
Insurgents in Afghanistan obtained more than two years ago several U.S. systems the military uses to jam signals that detonate improvised explosive devices, and they might have passed them on to Iran to research how the technology can be foiled, according to a Secret Army document posted on Monday by WikiLeaks.org.
