The Mojave Gunnery Range "C" (MGRC) is located in Kern County, California, and overlaps the southwestern portion of California City. The U.S. Army Corps of Engineers has identified eight project areas known as Munitions Response Sites, or MRSs, based on past uses for training in aerial bombing, strafing (firing of automatic weapons from aircraft onto ground targets), and air-to-ground rocketry. Between 1999 and 2011, the U.S. Army Corps of Engineers investigated MGRC to determine what kind of munitions hazards may remain in the MRSs and to estimate the quantity of those munitions. Site investigations indicate that MRS-01 and MRS-05 were bombing targets used for bombing and other air-to-ground training. As a result, the U.S. Army Corps of Engineers is conducting an instrument-aided surface removal of munitions items that are fully or partially visible on the ground at MRS-01 and MRS-05.
