As the war in Iraq drags on, the Army is accumulating a collection of problems that cumulatively could call into question the viability of an all-volunteer force.

They're using them at a very rapid pace in Iraq and Afghanistan.

One of the problems a modern army faces is that war fighters have to carry around a lot of electrical devices and heavy batteries,

This is really about a war plan that went wrong based on a series of bad decisions that reflected really abysmal intelligence.

Iraq is our war, our U.S. policy, our people (fighting) there ... it reflects the whole politics of what's going on in this country. We don't have a choice. We wouldn't be a significant news organization if we weren't reporting from there.

The last time the U.S. went to war with Iraq, the S&P dropped by 10 percent, the Dow by 10 percent. This issue is an artificial injection into the economic scenario that is hopefully a one-time affair. But it creates a lot of turbulence and sends people running for cover.
