One unit from Maryland - an Army National Guard engineering outfit from the Baltimore area - is expected to be part of the call-up, though officials declined to identify the unit until its members have been notified. The 150 soldiers in the unit are receiving an alert order, officials said, meaning that they will likely be called to active duty.
Four other Maryland Army National Guard units, including about 600 soldiers, are already serving in Iraq and Afghanistan, said Maj. Charles Kohler, a spokesman for the Maryland National Guard.
The Pentagon's troop rotation plan comes at a time of anxiety about the long deployments being endured by reservists and about the Bush administration's failure to persuade other nations to contribute more troops to the coalition force in Iraq.
Overall, the U.S. force in Iraq is projected to decline next year by more than 20 percent from its current level. That decrease, though, is based on the assumption of improved security, additional foreign troops and an expanded Iraqi security force.
One official said 28,000 of the troops would be called to duty within a month. The rest are to be activated in two increments, one on Dec. 15 and another after the first of the year.
In addition to the 43,000 reservists for Iraq, the Pentagon said it alerted 3,700 National Guard and Reserve troops who might be mobilized for Afghanistan.
Before yesterday's announcement, there were 154,603 members of the National Guard and Reserve on active duty.
"In this force rotation, we've tried to give people the longest notice possible so that they, their families, their employers will have some time to prepare," Defense Secretary Donald H. Rumsfeld said at a Pentagon news briefing.
Rumsfeld said the Army troops would be called up for a maximum of 18 months, with up to 12 months of that time in Iraq. The Marine mobilizations will be for 12 months, with up to seven months in Iraq.
The troop rotation plan includes 85,000 soldiers and Marines from active-duty units, including elements of the 1st Marine Division from Camp Pendleton, Calif., the 25th Infantry Division from Hawaii, the 1st Cavalry Division from Fort Hood, Texas, and the 1st Infantry Division, based in Germany.
Besides those active units, there are three Army National Guard combat brigades from
North Carolina, Washington and Arkansas, totaling about 15,000 soldiers, who will be sent to Iraq early next year.
It would be the second trip to Iraq for the 1st Marine Division, which played a key role in the three-week war, driving from Kuwait into Baghdad. But officials note that, with transfers to other units, many of the Marines who fought earlier won't be among those returning. About 20,000 Marines are expected to be part of the package.
Those active units will replace units now in Iraq, including the 101st Airborne Division, the 4th Infantry Division and the 1st Armored Division. The Pentagon had hoped to replace the 101st with another multinational division beyond the two there now. But the Bush administration has failed to persuade other nations to contribute to another division. There are now about 24,000 non-American forces in Iraq, about half of them British.
Marine Gen. Peter Pace, vice chairman of the Joint Chiefs of Staff, said the number of U.S. troops could be cut to about 100,000 by May, from the current 130,000. But officials cautioned that the reduction would depend on an improved security situation, more contributions of troops from other countries and an increase in the number of Iraqi security forces, which now stand at 115,000. Officials hope to increase the number of Iraqi forces to 170,000 by May.
"I am convinced we have one last shot at bringing the world into Iraq," said Sen. Joseph R. Biden Jr. of Delaware, the senior Democrat on the Foreign Relations Committee. "We must do everything in our power to seize it.
"I'd like to see President Bush go to Europe, call a summit and ask - ask - for more help. We might have to give up some more authority to get it. But as I keep saying, we've got to stop treating Iraq like some kind of prize."
Sen. John McCain, an Arizona Republican, said that to restore security in Iraq, the United States should expand its presence with at least another division, about 15,000 soldiers.
"We should increase the number of forces in-country, including Marines and Special Forces, to conduct offensive operations," McCain said this week. "Without better security, political progress will be difficult because the Iraqi people will not trust an Iraqi political authority that cannot protect them."
"The administration is pursuing a deployment strategy that is not based on long-term planning, but rather another ad-hoc effort to cobble together units to send to Iraq," Reed said. "The administration is ignoring the reality of an over-committed armed forces in order to meet their own promises to reduce troops in Iraq by next year."
The current Maryland Army National Guard units deployed in Iraq or the Persian Gulf region include 144 members of the 115th Military Police Battalion from Parkville and Salisbury, 163 members of the 1229th Transportation Company from Crisfield and Parkville, and 170 members of B Company, 2nd Battalion, 20th Special Forces Group from Glen Arm.
Serving in Afghanistan are 120 members of the 290th Military Police Company from Parkville, according to Kohler, the Maryland Guard spokesman.
