scope:

HERO includes, but is not limited to, vulnerable assets and sources. Vulnerable assets include nuclear weapons and conventional ordnance, such as gun systems and their munitions, missiles, bombs, countermeasures, aerial target drones, depth charges, mines, torpedoes, and other material embodying EIDs (e.g., cable cutters, chaff, and munition dispensers, selfdestruct devices, aircraft engine fire extinguishing systems, and aircraft ejection seats). Sources include aircraft and store EMR emitters, radars, antennas, radio frequency identification systems, wireless laptops and tablets, and handheld communication devices.

HERO also includes all equipment, subsystems, and materials containing EIDs, which affect safety and mission reliability. Safety and mission-critical EIDs are typically used to initiate explosives, chemicals, pyrotechnics, and similar stores on airborne, sea, space, and ground systems. For platforms, Chapter 6 applies.
