War strains U.S. military in tackling new crises
Admiral: Risk to capabilities remains significant, 15-month tours too long (full story)

I'm glad the Pentagon is on top of this one. I NEVER would have guessed that an endless, unpopular occupation would have an adverse impact on the military, or that repeated 15-month tours of duty were too long.

Good work there, fellas.
