  Target Numbering
  Target numbering is a system for expressing lethal and nonlethal actions against an
  entity or object considered for possible engagement or other actions. This numbering
  system identifies a wide array of mobile and stationary forces, equipment, capabilities,
  and functions that an enemy commander can use to conduct operations. The Army
  identifies targets using alphanumeric characters when selecting and prioritizing targets.
  The Army assigns target numbers that adhere to the provisions of NATO standardized
  agreement 2934.
  H-1. The targeting alphanumeric system represents the following-
  * Organizations.
  * Elements.
  * Cell, sections, or teams within a brigade size element.
  * Cell, sections, or teams within a BN size element.
  * Block of numbers.
  H-2. The target number is comprised of six characters consisting of two letters and four numbers in the
  following positions, for example AB1234. The two letters indicate the originator of the target number and
  the echelon holding the target data. The senior HQ establishes and publishes the assigned first letter in the
  operations order. The letter "Z" is the only permanently assigned first letter. The target number prefix "Z" is
  reserved for technical use by automatic data processing systems among nations when transferring target
  information from one nation to another. The second letter "E" is allocated for Service components forces in
  automatic data processing systems in those instances where a "Z" prefix target is generated for example "ZE."
  Table H-1 is an example of the assignment of first letters for targeting in an OE.

  H-3. Target numbers serve as an index to all other information regarding a particular target, such as location,
  description, and size. Normally, a common target numbering system is used at corps and within a major force.
  Target block numbers are traceable to its originating source to specific users. Corps down to BCT level may
  assign the second letter (A through Z). See table H-2.
