text: Non-Hostile Relations Between Belligerents
  Boundaries, Including Location of Forces
  7-88. An exchange of maps or other imagery showing the lines of opposing forces at the time of armistice
  commencement may facilitate understanding while reducing risk of confrontation. If agreed by the parties,
  locations of forces may be displayed.
  Neutral Zone
  7-89. Armistice elements may include a “neutral zone” situated between lines of demarcation sufficient in
  breadth to minimize risk of unintentional confrontation between opposing forces. A neutral zone does not
  exist absent express agreement between the relevant parties. One example of a neutral zone is the
  Demilitarized Zone between North Korea and South Korea.
  7-90. In the event of a general ceasefire, it may be sufficient to agree to a line rather than a zone. The line
  may include a buffer zone of specified depth between forces. It may be necessary for one or both parties to
  institute a partial withdrawal in order to establish a neutral zone. Whether a line or a zone, specificity as to
  either (such as through use of maps or Global Position System) is essential in order to minimize the risk of
  accidental breach or confrontation. For this purpose maps with the lines of the neutral zone indicated may be
  attached to and made part of the armistice. The extent of the zone will vary according to the circumstances
  and agreement of the parties. Historical examples have ranged from 1,000 yards to two miles, and in other
  circumstances have made use of the respective sides of a natural boundary, such as a river.
  7-91. A road or roads through the neutral zone should be identified by which communications between
  opposing forces must pass during the armistice.
  7-92. It is usually agreed that military personnel of either side may not encroach upon a neutral zone except
  by parlementaires or other parties by special arrangement for specified purposes, such as to search for and
  recover sick, wounded, or dead within the zone.
  Signals
  7-93. Signals may be agreed to for communication between opposing parties, whether for passage of
  parlementaire, a start or cessation of an armistice, or for other reasons.
  Language
  7-94. Unless agreement is possible for an armistice to be drawn up in one language, an armistice should be
  drawn up in the language of each belligerent force, with each side retaining a copy in its language. Each
  belligerent should confirm the text in each version to ensure consistency in each language.
  ADDITIONAL ELEMENTS
  7-95. Occasionally, an armistice contains additional elements that may be appropriate, such as addressing
  issues of a humanitarian nature.
  Relations of Forces with Local Population During Armistice
  7-96. In the terms of an armistice agreement, the contracting parties may settle what communications may
  be held in the theater of war with the inhabitants and between the inhabitants of one belligerent State and
  those of another (HR art. 39).
  7-97. “Communications” are not limited to electronic forms of communication and postal services, but refer
  to the movement of civilians and commerce as well. The rule applies with respect to citizens of a State divided
  by military operations between opposing forces. If changes in the relations between the opposing forces and
  the local population during the armistice are desired, this must be the subject of express agreement between
  relevant parties to the conflict. Otherwise, the relations remain unchanged. Each belligerent continues to
  exercise the same rights as before, including the right to deny or control all communications or movement of
  members of the civilian population between opposing lines.
