It can be difficult to obtain precise details on the DoD's daily oil hit, but an April 2007 report by a defense contractor, LMI Government Consulting, suggests that the Pentagon might consume as much as 340,000 barrels (14 million gallons) every day. This is greater than the total national consumption of Sweden or Switzerland.
Per NationMaster.com that puts the Pentagon just above Kuwait and just behind the Philippines in daily oil usage.
