1. U.S. 8-Inch Howitzer, M1/M115 Marker
The 8-inch Howitzer was known as a very accurate artillery piece that delivered a shell weighing over 200 lbs. The Westervelt Board findings of 1919 made the existing 155mm Gun and 8-Inch Howitzer systems inferior in range, traverse and elevation. The Ordnance Department found that the stresses of firing were similar in both the 155mm Gun and the 8-Inch Howitzer. Consequently, it was decided that the new systems would use the same carriage. The resulting system was the 155mm Gun, M2, and the 8-inch Howitzer, M1, which served the U.S. Army through World War II and the Korean War. The 8-Inch Howitzer rapidly gained a reputation for extreme accuracy throughout its range. Its dual-tired, double-bogie axle provided excellent cross-country mobility and was usually towed behind a 6 X 6 truck with a limber or with a tracked vehicle without the limber. In firing position, the wheels were jacked up and the entire carriage rested on the ground. Recoil energy was transferred to the ground by four spades, two at the end of the trails and two behind the carriage. The 8-Inch Howitzer, M1, remained in service after WW II. Consequently, it was given a "Century"
