This United States Army manual, Army Techniques Publication ATP 4-32 Explosive Ordnance Disposal (EOD) Operations May 2022, incorporates explosive ordnance disposal (EOD) doctrine in support of multi-domain operations such as large scale combat operations, but also includes lessons learned from operations in Iraq and Afghanistan. Rules of allocation for EOD companies have evolved to the current threat and ensure that EOD forces enable lethality. ATP 4-32 is the capstone EOD doctrinal publication which addresses the full range of military operations including support to combatant commanders on counter terrorism and irregular warfare. EOD forces are a key enabler to deter and defeat aggression, project power, defeat anti-access and area denial challenges, and counter weapons of mass destruction. EOD also supports civil and federal authorities in the defense of the homeland. Most stability, counter-insurgency, humanitarian, and disaster relief operations will require EOD support. This ATP implements public laws and regulatory guidance that directs the Services' EOD missions and provides Army doctrine for EOD in multi-domain operations. ATP 4-32 provides doctrinal guidance for EOD commanders and Soldiers on EOD operations. Commanders and staffs of Army headquarters serving as joint task force or multinational headquarters should also refer to applicable joint, multiservice or multinational doctrine concerning EOD operations to include JP 3-42. The principal audience for ATP 4-32 is all members of the profession of arms. Trainers and educators throughout the Army will also use this publication. ATP 4-32 applies to the Active Army, the Army National Guard/Army National Guard of the United States, and the United States Army Reserve unless otherwise stated.
