The Congressional Budget Office document provides information on approaches to reducing federal spending on national defense. It outlines options for reducing the defense budget, including reducing the size of the military, capping increases in military pay, replacing military personnel with civilians, increasing health care fees for retirees, and modifying or cancelling major weapons procurement programs. Each option includes estimates of potential budgetary savings over both short and long time horizons. The document also discusses arguments for and against each of the cost cutting approaches.
