An infantry unit at Joint Base Lewis-McChord in Washington has been locked down since last week after "sensitive" equipment was found to be missing, reports AP. Equipment, including laser-targeting gun sights, night-vision goggles, and weapons scopes in "the six-figure range" were missing and "definitely stolen," said an Army spokesman. A $10,000 reward has been offered, and the Army is conducting a criminal investigation. About 100 soldiers will remain locked down until the probe is complete. (More US Army stories.)
