I heard somewhere else where some Ret. Military officer was saying that Saddam was playing page by page (including burning trench full of oil around city)from old soviet war books. This could expalin why we have not seen more surrenders. I was wondering myself how anyone in a unit could surrender unless EVERYONE in that unit wanted to surrender. And how do you find out if everyone wants to surrender, without tiping your hand??????
There could also be much more which is happening which is censured b/c its part of the operation or b/c the media simply do not know everything.
Surrender is a top-down event. Troops obey command.
