Military officials have pulled back a sweeping multibillion-dollar contract intended to address military families’ long-standing problems with delays and damaged goods during their estimated 400,000 annual moves to assignments worldwide. The contract, which could have netted American Roll On Roll Off Carrier Group of Parsippany, N.J., up to $20 billion over nine years, is being re-examined by the U.S. Transportation Command after two competitors protested the award to the Government Accountability Office. Sources said that among the complaints was an allegation that the contract award failed to take into account the past criminal history of ARC’s parent corporation, Wallenius Wilhelmsen Logistics of Oslo, Norway. In July 2017, the U.S. Department of Justice announced that three Wallenius executives were part of a conspiracy dating to 2000 to allocate certain customers and routes, rig bids and fix prices for the sale of international ocean shipments of cargo to and from the United States.
