The changing role of the National Guard

Governor Tim Pawlenty is back in Minnesota today after a two-day visit with National Guard troops keeping the peace in Bosnia. The 1100 Minnesotans stationed there are the largest Minnesota deployment since the Second World War, and are part of a new emphasis on using Guardsmen and women to shoulder the country's growing military obligations. That new reality has left some wondering if they can afford to make the sacrifice. Minnesota Public Radio's Michael Khoo reports from Tuzla, Bosnia.
