Events have gone so well in Iraq after the surge I've only listed the significant weaknessess as noted by the best accounts of ground action as reported by The Long War Journal.
Significant weaknesses are:
• Logistics and intelligence are weak.
• The army will not start to aquire its first field artillery until 2009.
• Additional corps and support elements are being built and is needed for current force, but the force does need further expansion of line elements. The Iraqi Security forces are currently adding their fourth corps level joint command, Anbar Operational Command.
• Major increases in armored vehicles, especially tanks, are needed.
• The Iraqi Air Force is a decade from independence. It takes two years to train a pilot compared to only three months for an infantryman.
