Thirty thousand more troops by the summer. It's a daunting challenge laid out by President Obama, and it's now having the U.S. military scrambling to get it done.
Obama said Tuesday night the additional 30,000 troops would begin deploying early next year at "the fastest pace possible."
But before Obama's address, military leaders said it would be all but impossible to rush new troops to Afghanistan as quickly as they did Iraq.
A lot of it is going to be dictated by conditions on the ground: Can they build the new bases, the new roads, new infrastructure to handle this influx of troops?
