This most informative post at Instapundit is worth a read:
Said one of the biggest problems was money and regs. There was a $77 million gap between the supplemental budget and what he needed in cash on the ground to get projects started. Said he spent most of his time trying to get money. Said he didn't do much as a "combat commander" because the the war he was fighting was a war at the squad and platoon level. Said that his NCOs were winning the war and it was a sight to behold.
All praise to the American soldier.
