ORONO, Maine — About 150 Maine National Guard soldiers are being given a sendoff for a one-year mission in Afghanistan.

The deployment ceremony set for 7 p.m. Monday, Dec. 7, for B Company of the third battalion of the 172nd Mountain Infantry regiment at the Collins Center for the Arts at the University of Maine will be attended by Gov. John Baldacci and Maj. Gen. John Libby, the adjutant general of the Maine National Guard.

By early next year the Maine Guard will have deployed nearly half its strength to Afghanistan and Iraq.

The Brewer based B Company, and New Hampshire’s C Company based in Milford, are part of Vermont’s 86th Brigade Combat Team. All told, more than 3,000 soldiers from the brigade are expected to serve in eastern Afghanistan where they will work with Afghan national security forces.
