United States Army Garrison, Yuma Proving Ground (YPG) proposes to establish and operate a new high hazard impact area to accommodate weapon research, development, testing, and evaluation associated with artillery testing activities. The proposed 88 acre high hazard impact area would provide for longer range munitions and be used to support diverse test and training activities that require the firing of air-to-ground, ground-to-ground, ground-to-air, and air-to-air munitions. A variety of munitions would be fired into the impact area, including high explosive, illumination, obscurant, non-lethal, guided, and inert warheads.
