Defense: FY2012 Budget Request, Authorization and Appropriations [October 19, 2011] [open pdf - 657KB]
"President Obama's FY2012 budget request, sent to Congress on February 14, 2011, included $670.9 billion in discretionary budget authority for the Department of Defense (DOD), of which $553.1 billion was for the so-called 'base budget' of the department, that is the cost of routine, peacetime operations not counting the cost of ongoing operations in Iraq and Afghanistan. The remaining $117.8 billion in the DOD budget request was to cover the cost of so-called 'overseas contingency operations (OCO),' including operations in those two countries. […] The Senate Appropriations Committee reported on September 15, 2011, an amended version of H.R. 2219, the FY2012 DOD bill, which would provide $620.2 billion for DOD in FY2012, $29.39 billion less than the President requested for programs funded by this bill. Of the $29.13 billion by which the bill would reduce funding for the base budget, $9.9 billion was shifted into the part of the bill that funds OCO, where it would fund the activities for which it had been requested in the first place, principally operation and maintenance activities and a few procurement programs, notably including the purchase of three types of unmanned aerial vehicles (UAVs). Those funds shifted by the committee from the base budget into the OCO budget would offset funds the committee had cut from the OCO budget request, including $5.0 billion that was cut because of President Obama's announcement on June 22, 2011 that the number of U.S. troops in Afghanistan would be reduced by 33,000 by the end of FY2012."
