Editing Improvised explosive device (section)

====Infrared====
The British accused Iran and [[Hezbollah]] of teaching Iraqi fighters to use [[infrared]] light beams to trigger IEDs. As the occupation forces became more sophisticated in interrupting radio signals around their convoys, the insurgents adapted their triggering methods.<ref>{{Cite web|url=http://www.nationaldefensemagazine.org/issues/2007/June/BombMakingSkills.htm|archive-url=https://web.archive.org/web/20070814021913/http://www.nationaldefensemagazine.org/issues/2007/June/BombMakingSkills.htm|url-status=dead|title=Bomb Making Skills Spread Globally |work=National Defense |date=June 2007|archive-date=14 August 2007}}</ref> In some cases, when a more advanced method was disrupted, the insurgents regressed to using uninterruptible means, such as hard wires from the IED to detonator; however, this method is much harder to effectively conceal. It later emerged however, that these "advanced" IEDs were actually old [[Provisional IRA|IRA]] technology. The infrared beam method was perfected by the IRA in the early 1990s after it acquired the technology from a botched undercover British Army operation. Many of the IEDs being used against the invading coalition forces in [[Iraq]] were originally developed by the British Army who unintentionally passed the information on to the IRA.<ref>{{cite news | url=http://news.independent.co.uk/uk/ulster/article320004.ece | title=Revealed: IRA bombs killed eight British soldiers in Iraq |work=The Independent | date=16 October 2005 | access-date=18 October 2009 | location=London | first1=Greg | last1=Harkin | first2=Francis | last2=Elliott | first3=Raymond | last3=Whitaker | url-status=dead | archive-url=https://web.archive.org/web/20080709005403/http://news.independent.co.uk/uk/ulster/article320004.ece | archive-date=9 July 2008 }}</ref> The IRA taught their techniques to the Palestine Liberation Organisation and the knowledge spread to Iraq.<ref>{{cite news |first=Kevin |last=Myers |url=http://www.independent.ie/opinion/analysis/the-death-of-the-tank-took-place-around-crossmaglen-2131116.html |title=Kevin Myers: The death of the tank took place around Crossmaglen |department=Opinion |work=The Independent |date=9 April 2010 |access-date=11 May 2012|archiveurl=https://web.archive.org/web/20220506003322/https://www.independent.ie/opinion/columnists/kevin-myers/kevin-myers-the-death-of-the-tank-took-place-around-crossmaglen-26648094.html|archive-date=May 6, 2022}}</ref>
