"H.R. 5132 would express the sense of the Congress that the increases in end-strength authorizations for the armed forces for fiscal year 2003 recommended by the Senate and House of Representatives in their respective versions of the National Defense Authorization Act for Fiscal Year 2003 are wholly appropriate and justified by the increased missions and tempo of operations associated with prosecution of the war against terrorism. In addition, the bill would express the sense of the Congress that the President and the Secretary of Defense should not reduce, or seek to reduce, the number of members of the armed forces, and that the President should support the increase in end-strength levels for the armed forces recommended by the Senate and House of Representatives for fiscal year 2003 because of the demands of the war against terrorism."
