This time, it’s Army Small Arms competition with rack issue carbines and pistols that’s open to active duty, guard, reserve and cadets, to keep battlefield skills sharp. The Army Marksmanship Unit hosts the challenges on the ranges at Fort Benning. Plus, the big guns, Dirty Harry's Model 29. And, then the .500 S&W Magnum and the Lever Carbine chambering the .500 for even more power in the woods.
