  Electromagnetic Warfare Reprogramming
  This appendix provides general procedures in conducting electromagnetic warfare
  reprogramming, divided into four phases. It will also describe the three major
  categories of electromagnetic warfare reprogramming and associated actions. It will
  also discuss the joint coordination of electromagnetic warfare reprogramming.
  PURPOSE OF ELECTROMAGNETIC REPROGRAMMING
  F-1. The purpose of EW reprogramming is to maintain or enhance the effectiveness of EW and TSS
  equipment. EW reprogramming includes changes to self-defense systems, offensive weapons systems, and
  intelligence collection systems. Each Army unit is responsible for reprogramming of EW and TSS equipment
  using an established EW reprogramming support program.
  F-2. Units from all Service components that identify threat signature changes report those changes through
  higher headquarters to the CCMD of the AOR in which they are conducting operations. The Service
  intelligence production center [National Ground Intelligence Center for the Army]; and Service equipment
  support for effected EW and TSS equipment.
  F-3. The CCMD ensures promulgating the threat signature changes worldwide and to Service components
  operating through the AOR using joint coordination electromagnetic warfare reprogramming policies and
  procedures developed by the Joint Staff. The Intelligence Production Center collects the data to process and
  analyze to identify and understand the threat signature change. Service equipment support conducts flagging
  activities while analyzing EW and TSS equipment for compatibility and system impact assessment.
  Note. EW reprogramming is only required for EW and targeting sensing software that operate
  using downloads of threat signatures. With these systems, EW reprogramming occurs when threat
  signatures have changed. Dynamic EW capabilities do not require downloads of threat signatures
  and thus do not require EW reprogramming.
  CATEGORIES OF ELECTROMAGNETIC WARFARE
  REPROGRAMMING
  F-4. Several types of changes constitute EW reprogramming. These changes fall into three major categories
  of EW reprogramming. They are –
  * Tactics. Include changes in procedures, equipment, settings, or EW systems mission-planning
  data. These changes are usually conducted at the Service level and implemented at the unit level
  using organic personnel and equipment.
  * Software. Include changes to the programming of computer-based EW and target sensing
  software. This type of change requires software vendors to alter programmed look-up tables, threat
  libraries, or signal sorting routines.
  * Hardware. Hardware changes or long-term system development are necessary due to tactics and
  software changes installed to resolve deficiencies. These changes usually occur tactical, and
  software changes are of such complexity that it requires hardware modifications or upgrades.
