Well.
First that isnt the plan. At first it was "haul ass and bypass" but that was when the marines were still on the Kuwait boarder. They are trying to secure towns as the come to them, however urban conflict is a bitch so they arent totally secure. Like Basrah its under control, but its not secure. The people that came under ambush were ambushed by Iraqis wearing civilian clothing, and it was during battle over the same town but it was in the rear that they were attacked, again by Iraqis wearing civilian clothing.
Also the 7th Calvary is part of the 3rd infantry division, its the recon unit in it. The 3rd infantry divison is a HUGE divison, the goal is to get them to Baghdad as quickly as possible, but they ARE not purposely avoiding battles. Infact they have been fighting constantly since Saturday afternoon. The 3rd infantry divison isnt going to attack Baghdad on its own, its job is to get there are surround it while waiting for the British and Marines to catch up.
WTF are all you people saying its going to take to long or some crap about the draft.
Yes we have KIAs but out of a force of 300,000 30-40 is .01%. Yes we have more that are wounded. But we arent sustaining heavy casualities. Its about the same as Desert Storm except we are pushing much much farther into Baghdad.
