In the May 2005 issue of the Atlantic Monthly article Robert Bryce says that "The U.S. military now uses about 1.7 million gallons of fuel a day in Iraq. ... each of the 150,000 soldiers on the ground consumes roughly nine gallons of fuel a day. And that figure has been rising." This mean in Iraq each day 40 000 b/d of oil is consumed by the US military."

"According to the US Defense Energy Support Center Fact Book 2004, in Fiscal Year 2004, the US military fuel consumption increased to 144 million barrels. This is about 40 million barrels more than the average peacetime military usage.

By the way, 144 million barrels makes 395 000 barrels per day, almost as much as daily energy consumption of Greece."

"In fiscal 2005, DESC will buy about 128 million barrels of fuel at a cost of $8.5 billion, and Jet fuel constitutes nearly 70 percent of DoD's petroleum product purchases." says American Forces Information Service News Article by G. J. Gilmore. [3]

The US military oil consumption overseas and the world oil demand
"
According to the Defence Logistic Agency's Web Site, as of November 2005 more than 2.1 billion gallons of fuel have been used in support of Operation Enduring Freedom (since October 2001; war on terrorism in Afghanistan).
"

For some, this is not enough though. Here is what a report from Office of Under Secretary of Defense says "Because DOD's consumption of oil represents the highest priority of all uses, there will be no fundamental limits to DOD's fuel supply for many, many decades." [4]

it is a bit scary to thing that this Army will have to secure the flow of oil to be able to secure it.
