Our battalion was equipped with the 15mm M-109. Still, I had howitzer envy for the First Battalion, which fired the 8-inch M-110. Talk about BIG and LOUD! Firing a mile away from us, they were louder than our own guns, just 50 yards away. Of course, 200-lb. shells for the 8-inch make for very muscular, but slow, gunbunnies.
Ya' sure those aren't Gun Buffalo? LOL
