U.S. Troops Setting Up Camp In Poland, Miles From Ukraine Border

President Biden recently deployed 7,000 service members to NATO's eastern flank, adding to the 4,000 already there.

On Tuesday, a senior U.S. defense official reiterated that U.S. troops will not be fighting in Ukraine, and that includes in the use of a no-fly zone, saying there's no discussion about it.

But U.S. troops are still heavily deployed in Poland in a show of force for an important NATO ally. 

U.S. troops with the 82nd Airborne Division arrived with a mobile radar unit, Humvees and other heavy equipment.
