  ELECTROMAGNETIC WARFARE REPROGRAMMING ACTIONS
  F-5. During a crisis or enemy EA, EW reprogramming provides commanders with a timely capability to
  respond to threat systems changes and correct EW and targeting sensing systems. Through EW
  reprogramming, commanders can also adjust EW, TSS deficiencies and tailor EW and TSS to meet unique
  mission requirements. EW reprogramming enables this capability using three different EW reprogramming
  actions, either individually or simultaneously. These reprogramming actions are–
  * Threat changes. Any changes in the operation or electromagnetic signature of a threat system.
  The design of EW reprogramming is to respond to threat changes that affect EW’s combat
  effectiveness and TSS.
  * Geographic tailoring. The reprogramming of EW and targeting sensing systems for operations
  in a specific area or region of the world. Geographic tailoring reduces the number of system
  memory threats, decreasing systems processing time, and reducing error displays.
  * Mission tailoring. The reprogramming of EW and targeting sensing systems for the mission of
  the host platform. Mission tailoring may improve system response to the priority threat(s)
  identified by the host platform.
  GENERAL ELECTROMAGNETIC WARFARE REPROGRAMMING PROCESS
  F-6. There are four phases to the EW reprogramming process. Units can further refine the last three phases
  of the EW reprogramming process to meet their unique requirements. The four phases of the EW
  reprogramming process are—
  * Determine the threat.
  * Determine the response.
  * Create a change.
  * Implement the change.
  Determine the Threat
  F-7. When determining the threat, units develop and maintain an accurate description of the EMOE,
  specifically threat systems and tactics. Document submitted IRs to maintain an accurate description of the
  EMOE at all times. IRs are important since EW and TSS equipment are each programmed to identify and
  respond to a particular threat or target signature data. An accurate description of the EMOE requires the
  fusion of known electromagnetic data with the collection, analysis, and validation of threat signature changes
  divided into three steps:
  * Collect data. Threat signature data collection is the collection of threat system parametric
  information and is the responsibility of the G-2 or S-2. The collection of signature data may be a
  matter of routine intelligence collection against targeted systems. Other data collection may occur
  because of urgent intelligence production requests. Regardless of the purpose of collection,
  signature data disseminates through the intelligence channels to the National Ground Intelligence
  Center and the EW and TSS Service equipment support channels for analysis and flagging
  activities.
  * Identify changes. EW and TSS Service equipment support analyzes the collected data for
  compatibility. Incompatible data is flagged for further analysis and system impact assessment. The
  National Ground Intelligence Center uses the collected data for processing and analysis to identify
  threat signature changes in the EMOE. Identified changes are further analyzed.
  * Validate changes. Once an identified signature change is correlated to a threat system and
  analyzed, it is further analyzed to validate an actual system capability change or determine it as a
  probable malfunction. Information on threat system engineering and tactical employment are
  critical during this step. The National Ground Intelligence Center or the Defense Intelligence
  Agency(s) typically provide technical analysis and validation of threat changes. At the joint level,
  the CCMD must provide the identification, technical description, and analysis of threat change
  validation messages expeditiously to component commands and Service reprogramming centers
