Iraq, Afghan wars reportedly strain U.S. fighting ability

"The senior military official told CNN that because of the U.S. deployments in Iraq and Afghanistan, the report concludes that future armed conflicts would last longer and produce higher casualties.

The report finds that the United States still would have the ability to win another military face-off but wouldn't be able to build up its forces as quickly as it did for the Iraq war.

'It would be harder to sprint that fast,' the official said.

The report cites areas in particular stress: stockpiles of precision weapons and the availability of pre-positioned equipment, including vehicles, and reserve units -- who are providing much of the combat support in Iraq."
