Retreat - do not approach, touch, move, or disturb a suspect munition, but carefully leave the area.

Report - call 911 and advise the police of what you saw and where you saw it.

Former Fort Huachuca - Artillery, Mortar Ranges & Maneuver Area

The former Fort Huachuca is located in Cochise County, Arizona. The U.S. Army Corps of Engineers is investigating and monitoring the former training range through the Formerly Used Defense Sites, or FUDS, Program for munitions and explosive hazards that may remain from previous military training activities. This page provides information on the Artillery, Mortar Ranges & Maneuver Area project, which is part of the Fort Huachuca FUDS.

In September 1943, Fort Huachuca expanded one of its ranges, the East Artillery Range, by leasing 3,219.92 acres of land from the Boquillas Land and Cattle Company. The leased land was used for artillery and infantry training. Historical records indicate that the Artillery, Mortar Ranges & Maneuver Area project contains portions of three sub-ranges: a 623-acre artillery range, a 1,297-acre mortar range, and a 505-acre maneuver area.

The U.S. Army Corps of Engineers began investigating the former Fort Huachuca in 1999 through the FUDS Program for munitions that may remain from former military training activities. In 2015, the U.S. Army Corps of Engineers completed a Remedial Investigation and Feasibility Study for the Artillery, Mortar Ranges & Maneuver Area project. Based on the Remedial Investigation findings, the U.S. Army Corps of Engineers divided the Artillery, Mortar Ranges & Maneuver Area project into the following three Munitions Response Sites: MRS02–Artillery/Mortar Range, Range Safety Buffer Area, MRS03–Artillery/Mortar Range, Potential Target Area A, and MRS04–Artillery/Mortar Range, Potential Target Area B.

The 2016 Proposed Plan for remediation of munitions hazards at the Artillery, Mortar Ranges & Maneuver Area project is available for public review at the Sierra Vista Public Library. The Proposed Plan highlights the previous investigations at the site and presents the U.S. Army Corps of Engineers’ proposed remedial alternatives for each of the munitions response sites. Since the U.S. Army Corps of Engineers is committed to seeking community input throughout the decision making process, Sierra Vista community members are encouraged to review the Proposed Plan and provide comments during the 30-day public comment period from June 27 to July 27, 2016. Public comments will be considered as the U.S. Army Corps of Engineers selects the final remedial alternative.
