From the Summary: "The President's FY2008 federal budget request, released February 5, 2007, included $647.2 billion in new budget authority for national defense. In addition to $483.2 billion for the regular operations of the Department of Defense (DOD), the request includes $141.7 billion for continued military operations, primarily to fund the campaigns in Iraq and Afghanistan, $17.4 billion for the nuclear weapons and other defense-related programs of the Department of Energy, and $5.2 billion for defense-related activities of other agencies. The $483.2 billion requested for DOD's 'base' budget-that is, the request for regular operations excluding the cost of ongoing combat activity-is $46.8 billion higher than the agency's base budget for FY2007, an increase of 11% in nominal terms and, by DOD's reckoning, an increase in real purchasing power of 8.0%, taking into account the cost of inflation. The House passed on May 17 its version of H.R. 1585, authorizing $1.2 billion more than the President's request. The bill would cut hundreds of millions of dollars from several technologically advanced weapons programs while increasing funds for improvements in U.S. forces' near-term combat capabilities. The Senate Armed Services Committee reported its counterpart bill, S. 1547, on June 5. The Senate substituted the text of that measure for the House-passed text of H.R. 1585 when it began debating the latter bill on July 9. After several days of debate dominated by Democratic-led efforts to force a withdrawal of U.S. combat troops from Iraq, the Majority Leader, Senator Reid, set the bill aside indefinitely on July 18."
