So let us assume this plan calls for a Division of five combat Army brigades, with each combat brigade having an engineer battalion, a combat support battalion, and a field arty battalion. That is somewhere around 16,000 Army troops. Now toss in two Marine Regiments. Throw in the DoD and civilian support.
That is not going to happen on $10 billion. And it d@mn sure is not going to be sustainable for any period of time with current overall force levels. Unless one thinks it is wise to send troops on 18 month tours, give them 30 days R&R, and send them back for another 18 months.
The ten billion would not be included in the costs for the grunts and support. The ten billion would, presumably, be the carrot after the stick in Baghdad.
