Congress is set to launch an investigation into a brewing Army scandal over the difficulty some units have had in securing a software system designed to predict the location of roadside bombs -- the No. 1 killer of American troops in Iraq and Afghanistan. 

Though the software, called Palantir, is already being used by some troops in Afghanistan, more units have been requesting it and some of those requests remain unfulfilled. The 1st Brigade, 82nd Airborne Division sent a request in May citing an "urgent need" for the intelligence-gathering system and has yet to receive it. 

What's more alarming, said Rep. Duncan Hunter, R-Calif., a member of the House Armed Services Committee, is that the Army stands accused of destroying internal reports that favor Palantir over its own system. 

"The problem is (the Army) fell in love with their own software," Hunter told Fox News.
