His Last War Unfinished, Top Sergeant Exits Afghanistan

Command Sgt. Maj. Mike Hall retired from the Army after 32 years of working special operations on five continents. But he was called back to duty for one last tour — in Afghanistan — by Gen. Stanley McChrystal, the former top U.S. and NATO commander in the country. Now, as he prepares to end his tour, Hall says insurgents have lost momentum — while the U.S. has yet to gain it — but that the war in Afghanistan can still be won.
