It looks like there are could be major additions to the ground combat forces in Iraq. According to the this Reuters article, the 1st Armored Division in Germany, the 1st Cavalry Division in Texas, and the 2nd Armored Cavalry Regiment in Fort Collins, CO (although maybe they mean the 3rd Armored Cavalry Regiment based in Fort Carson, Colorado Springs, CO–according to Global Security, the 2nd ACR is based in Fort Polk, LA) are all slated to move. That’s in addition to the 4th Infantry Division, which has been off the coast of Turkey for over month waiting for permission to land. They didn’t get it, of course, and the ships are now headed for Kuwait. All of these units were alerted to deploy weeks or months ago, but sealift limitations (and maybe predictions of a one week war) left them mostly in their home bases.
In addition, the airfield that the 173rd Airborne seized yesterday is being prepped to receive the 1-63 Armor of the 1st Infantry Division in Germany. Their M1 tanks can only be flown in one per plane, but I read that a battallion (about 58 tanks or IFVs) can be flown in every two days.
