Yuma Proving Ground

Yuma Proving Ground (YPG) is a United States Army series of environmentally specific test centers with its Yuma Test Center (YTC) being one of the largest military installations in the world. It is subordinate to the U.S. Army Test and Evaluation Command.

YPG's headquarters is located at its YTC in southwestern La Paz County and western Yuma County in southwest Arizona, United States, approximately north of the city of Yuma.

Of the four extreme natural environments recognized as critical in the testing of military equipment, three fall under the management authority of YPG. Realistic natural environment testing ensures that American military equipment performs as advertised, wherever deployed around the world. YPG manages military equipment and munitions testing at three locations: The Arctic Regions Test Center at Fort Greely, Alaska; the Tropic Regions Test Center operating in Panama, Honduras, Suriname, and Hawaii; and at YTC. The common link between these test centers is "environmental testing," which makes the proving ground the Army's environmental test expert. }} Provided by Wikipedia
