According to a recent survey of U.S. troops in Iraq by the military's own Stars and Stripes newspaper, the Bush administration's approach to Iraq risks doing to the AVF [All-Volunteer Force] what Vietnam did to the conscript service. After polling almost 2,000 troops, Stars and Stripes found that one-third of them thought the war against Saddam Hussein had been of little or no value and that their mission lacked clear definition. A full 40 percent said that their missions had little or nothing to do with what they had trained for. And, most ominously, about half of the soldiers surveyed indicated they will not reenlist when their tours end and the Pentagon lifts the "stop-loss order" now in place, which prevents troops from retiring or leaving the service when their enlistment contract expires.
Were it not for this stop-loss policy, which even high-ranking officials admit is inconsistent with the principles of voluntary service, the AVF and the Total Force [i.e., heavy reliance on Guard and Reserve units for post-conflict operations] would be in severe jeopardy, lacking the peronnel to complete their missions. For example, as one infantry battallion commander deployed in Kuwait and headed for Iraq recently told The Army Times he would have lost a quarter of his unit in the coming year had it not been for the order. Through a series of such stop-loss measures, the army has prevented 24,000 active-duty troops and 16,000 reservists from leaving its ranks. Yet even with these rules in place, the Army Reserve missed its reenlistment goals for fiscal year 2003.
