The Rhino Passive Infrared Defeat System (also known simply as Rhino) was an early detonation Counter-IED system. It was mounted to the front of a vehicle and used heat to prematurely detonate any hidden improvised explosive devices (IEDs) while the vehicle was at a safe distance away from the blast. It was developed by the Joint Improvised-Threat Defeat Organization (JIEDDO) in 2006 during the war in Iraq to counter the rise of IED-related deaths.
