From the summary: “Since 2001, the Department of Defense (DOD) has regularly requested and received large appropriations to augment the base-budget funding provided in its regular, annual appropriations. The additional, or nonbase, funding has totaled about $2.2 trillion, amounting to about 20 percent of total defense appropriations over that time. About 98 percent of that sum has been designated for military operations in Iraq, Afghanistan, and elsewhere— known as overseas contingency operations (OCO)—that began after 9/11.”
