Aerospace and defence group BAE has made a complaint to the US Government Accountability Office (GAO) asking it to review a US Army decision to award a vehicle contract to one of its competitors.BAE had been hoping the Army would use BAE's Family of Medium Tactical Vehicles (FMTV) programme. The contract was won by the US military truck maker Oshkosh.'The company believes that the Army did not properly evaluate the proposals, consistent with the government's stated requirements, and the Army failed accurately to assess the various risks associated with the different proposals,' BAE said.
