Yuma Proving Ground is one of the largest military installations in the world. The proving ground holds testing of nearly every weapon system in the ground combat arsenal. It is located near the Arizona-California border, adjacent to the Colorado River, approximately 24 miles north of the city of Yuma, Arizona. Situated in the southwest portion of the state, the proving ground is in the heart of the great Sonoran Desert. Yuma is the largest city in Arizona outside the metro areas of Phoenix and Tucson.


Yuma proving ground (YPG) is part of the U.S. Army Test and Evaluation Command and is a multiple purpose test facility. Specific proving ground capabilities include testing of: artillery, mortars, mines, ground and aircraft weapons, target acquisition and fire control systems, wheeled and tracked vehicles, and air delivery materiel, equipment and techniques.

Arriving at Yuma Proving Ground
If you’re assigned to Yuma Test Center, and if you are arriving during duty hours, you should report directly to the Military Personnel Division (MPD), Building 501. MPD is located on Howard Cantonment Area and across from Army Community Service, Bldg. 309. If you are arriving after duty hours, on a weekend or holiday, you should report to the InterContinental Hotels (IHG), on base, or where your reservation has been made. Please verify with your unit for procedures. When you report to Building 501, ensure you have the documents in your possession as mentioned under, Important Documents to Hand Carry for In-processing.


An in-processing checklist will be issued by your individual unit. Individuals will also need to have all financial papers related to their PCS. The sponsor will escort the new soldier for during the in-processing period as much as possible. The sponsor will be his/her mentor to ease the transition. Should you not be assigned a sponsor, you may request one. A quarterly Newcomer’s Orientation is held at the Palm Garden Conferencing Center, Bldg. 530, or as determined. Your Commander or supervisor will inform you of your attendance requirement. Family members are welcomed but not required to attend. Childcare is not provided. An assessment is made during in-processing at Army Community Service and will answer your questions or concerns you may have. A welcome packet is available, if one was not mailed.


All other incoming personnel (Health Clinic; Military Freefall School, USASOC Flight Detachment, and Veterinary Treatment Facility), follow your unit’s procedures.
