The Oskosh Corporation is getting heat for their latest big Army contract. A $3 billion contract to build trucks for the U.S. Army is being challenged by a rival company because of how the Fox Valley company won the bid. So, Oshkosh VP of Marketing Ann Stawski says they're going on a advertising blitz in Washington D.C. BAE Systems Inc. of Texas is filing the challenge to the Government Accountability Office over the process used by the Army to name a winning bid. John Suttle with the contractor says the Army didn't follow through on their promise to look at the "best value" bid, they just went by lowest price. Suttle indicates that was only supposed to be 40 percent of the deicision. He maintains this isn't a beef with Oshkosh, but with the Army. A decision from the Government Accountability Office is expected December 14th.
