O8 的支出不包括特別支出，就是單單國防預算

On February 1, 2010, President Barack Obama sent to Congress a proposed defense budget of $708 billion for fiscal 2011. The budget request for the Department of Defense (DoD) includes $549 billion in discretionary budget authority to fund base defense programs and $159 billion to support overseas contingency operations (OCO), primarily in Afghanistan and Iraq. The fiscal 2011 base budget request represents an increase of $18 billion over the $531 billion enacted for fiscal 2010. This is an increase of 3.4 percent, or 1.8 percent real growth after adjusting for inflation.
