I’ve noted the new MC-B mortar Stryker variants before, and even posted a photo in March of one letting go with its 120mm mortar. But this pic is too sweet to ignore:
U.S. Army soldiers from 1st Battalion, 17th Infantry Regiment, fire illumination flares with a 120mm mortar cannon from a Mortar Carrier Stryker vehicle over Mosul, Iraq, June 1, 2006. U.S. Air Force photo by Tech. Sgt. Jeremy T. Lock
That would be the, um, 172nd regiment. But we knew what they meant. Photo from DoD Transformation.
UPDATE: Whoops. I was rushing and blew it. A commenter points out that the 17th regiment is part of the 172nd brigade. My bad.
