The 52nd Ordnance Group (EOD) is the command and control headquarters for all U.S. Army explosive ordnance disposal (EOD) companies and battalions located east of the Mississippi River in the Continental United States (CONUS). Subordinate units maintain EOD Response Teams, which evaluate, render safe, and remove conventional, chemical/biological, or nuclear ordnance, or improvised explosive devices that pose an immediate threat to public safety. While subordinate units are trained and equipped for combat operations, they may also support a variety of peacetime missions, to include range surface clearance operations of active U.S. Army installations, EOD and UXO operations in support of civilian law enforcement agencies, and support to the US Secret Service for protection of VIPs.
