American GI is the most energy-consuming soldier ever seen on the field of war
“The Army calculated that it would burn 40 million gallons of fuel in three weeks of combat in Iraq, an amount equivalent to the gasoline consumed by all Allied armies combined during the four years of World War I.” [1]
In May 2005 issue of The Atlantic Monthly, Robert Bryce gives another example; “The Third Army (of General Patton) had about 400,000 men and used about 400,000 gallons of gasoline a day.
