New Hampshire's elected officials joined the state's military leaders to welcome home a medevac unit that recently returned from Afghanistan. The 169th MEDEVAC unit went to Afghanistan in September 2012. Made up of National Guard units from New Hampshire, New York, Pennsylvania and Missouri, the group became known as "Jigsaw'' to reflect the merger of different units. The medics performed 471 lifesaving missions and carried 427 patients to higher levels of care. Soldiers in the unit, which returned in August, earned several medals including Bronze Stars. The ceremony was at 11 a.m. Saturday, at the Army Aviation Support Facility in Concord. Governor Maggie Hassan, U.S. Sens. Kelly Ayotte and Jeanne Shaheen and U.S. Reps. Annie Kuster and Carol Shea-Porter were set to attend.
