Mysterious illnesses among soldiers are so common they often go unresolved.

But this time there may be justice for National Guard soldiers who have been getting sick since 2003 when they were exposed to chemicals in Iraq.

Lawyers for the soldiers claim to have found evidence which shows that KBR, a former subsidiary of Halliburton, knew there were harmful chemicals on a site U.S. soldiers were sent to guard, reports Nigel Duara at the Associated Press.

KBR has always maintained it had no idea sodium dichromate, the carcinogenic from Erin Brockovich, was at the Qarmat Ali water treatment plant, despite having sold Iraq 8 million pounds of the toxin before the U.S. invasion in 2003.

For a little context, consider that in February 2003 Halliburton had already been tapped by the administration to fight oil well fires in Iraq through a move critics said was due to Cheney's close ties to the company.

One month after KBR got the contract, soldiers from the Oregon National Guard were tasked with providing security to KBR staff restoring the treatment facility. It wasn't until July of that year that company executives acknowledged the poison was on site.

The new evidence allegedly shows that KBR knew about the poison by January 2003 at the latest, lawyers for the soldiers told the AP.
