The United States is spending $1.23 billion this year to come up with better ways to deal with IEDs (improvised explosive devices; roadside and suicide bombs) in Iraq, and elsewhere. While a lot of effort has gone into developing more armor and jamming, the research has also revealed that more, and better, training will probably be more effective in producing lower casualty rates. Its been noted that better trained units have suffered noticeably lower casualties from IEDs. These units, as many do, implemented their own additional training programs, and these are being used to come up with new, mandatory, training for all units operating in Iraq. This is not the first time that training proved to be the most successful bit of equipment on the battlefield. However, its apparently human nature to first look for a hardware solution.
