M107 175mm Self-Propelled Gun
From Wikipedia, the free encyclopedia
The M107 175mm Self-Propelled Gun was largely deployed in NATO areas and its ammunition was commonly used throughout NATO forces. Designed to be part of a common family of weapons utilising the same chassis components, the M107 and M110 were essentially the same vehicle mounting different barrels. These guns fired an HE shell weighing 66.6 kilograms at a muzzle velocity of 914 meters per second. The M107 was used extensively in Vietnam to provide long range fire support (being able to fire more than 30 km) and took part in numerous cross-DMZ duels with NVA guns. Though withdrawn from service in the United States, vehicles of this type remain in service in the militaries of some other countries.
