Anodizer, you keep harping on "low morale". I don't know a single member of the military that suffers from it. And I know a fairly large number of them. They ALL want to go home. But they all want to finish the job. They're just like anyone else away from home doing a job. They want to finish the job and go home. Their morale is not so low as you try to proclaim. Re-enlistment is up, as well as enlistment.
By the way, the way this operation would be done, if it were to be done, would be the way it has been planned for decades. It would NOT be an armor v. armor battle, nor an infantry v. infantry battle, nor a combination. Air superiority would be established quickly, and the A-10's, helicopters, and other attack aircraft would be sent in to deal with the armor. Then, for the most part, the naked infantry would retreat on its own.
