As president mulls troop decision, intensity of conflict takes toll on troops.
As President Obama weighs his decision about U.S. strategy in Afghanistan, another factor has come into play, the declining morale of U.S. troops there.
It has been eight years since the first U.S. combat troops put boots on the ground in Afghanistan and many of them have since been deployed three, four or even five times. The strain is taking its toll. According to a recent report by the U.S. Army, soldiers' perception of their units' morale has dramatically decreased over the past two years.

Bill Nash is a retired major general who led forces in Bosnia in the 1990s. "That's where the great stress comes from," Nash says. "And that's a reflection of a small military force and that small force being a minuscule fraction of the population of the nation. So the burdens are not shared, and unshared burdens bring about stress."
