Was the first produced in 1963. It had a 155 mm M126 gun in an M127 Howitzer Mount, and carried 28 rounds of 155 mm ammunition. It was also armed with a .50cal M2HB machine gun with 500 rounds of ammunition. It's the more basic and simple M-109, but was the original. Done in MAX 2013, only the tracks and lights are textured, maps included, the rest untextured.
