U.S. outsmarted and out-maneuvered by small band of insurgents

This is a pretty shocking assessment of things from the "greatest Army in the world."

The US army is lagging behind Iraq's insurgents tactically in a war that senior officers say is the biggest challenge since Korea 50 years ago.

… In a bleak analysis, senior officers described the fighters they were facing in Iraq and Afghanistan 'as smart, agile and cunning'.

In Vietnam, the US was eventually defeated by a well-armed, closely directed and highly militarised society that had tanks, armoured vehicles and sources of both military production and outside procurement. What is more devastating now is that the world's only superpower is in danger of being driven back by a few tens of thousands of lightly armed irregulars, who have developed tactics capable of destroying multimillion-dollar vehicles and aircraft.

By contrast, the US military is said to have been slow to respond to the challenges of fighting an insurgency. The senior officers described the insurgents as being able to adapt rapidly to exploit American rules of engagement and turn them against US forces, and quickly disseminate ways of destroying or disabling armoured vehicles.
