  * Military ground, air, and naval units and army, air, and naval bases (other than medical facilities
  and POW camps), whether used for training, billeting, or staging, or for offensive or defensive
  purposes, to include headquarters, command and control centers, defense ministries, or
  intelligence establishments.
  * Facilities used by enemy leaders as headquarters for military operations or otherwise to command
  military operations. In some cases, enemy leaders themselves may be made the object of attack.
  * Communications objects (such as facilities, networks, and equipment), that could be used for
  command and control of military operations or intelligence gathering.
  * Economic objects associated with military operations or with war-supporting or war-sustaining
  industries, to include power sources and oil refining and distribution facilities and objects
  associated with petroleum, oil, and lubricant products (including production, transportation,
  storage, and distribution facilities).
  * Transportation objects, to include facilities (for example, port facilities and airfields) and
  equipment that could be part of lines of communication (for example, highways, railroads,
  waterways, and bridges connecting military forces with logistics depots and storage areas).
  * Geographic areas or features of land that are military significant, to include road networks; known
  or suspected enemy avenues of approach or withdrawal; mountain passes, hills, defiles, and
  bridgeheads; and villages, towns, or cities whose seizure or defense is militarily important.
  The following persons and objects are not military objectives and so are protected from being made
  the object of attack, so long as those protections have not been forfeited:
  * Individual civilians and the civilian population as such;
  * Military medical personnel and chaplains (see Chapter 4 for rules governing these personnel);
  * Individuals who are hors de combat;
  * Civilian objects or other protected objects, that is, all objects that are not military objectives;
  * Medical units, transport, and equipment (see Chapter 4 for rules governing these objects); and
  * Undefended villages, towns, and cities (see paragraphs 2-122 through 2-129).
  COMBATANTS
  In general, combatants, whether privileged or unprivileged, may be made the object of attack at all
  times regardless of their activity, provided they have not been placed hors de combat.
  ARMED FORCES AND GROUPS AND LIABILITY TO BEING MADE THE OBJECT OF ATTACK
  Membership in the armed forces or belonging to armed groups, that is, affiliation with these groups,
  makes a person liable to being made the object of attack regardless of whether he or she is taking a direct
  part in hostilities. Moreover, the individual, as an agent of the hostile group, may be assigned a combat role
  at any time, even if the individual normally performs other functions for the group. Thus, with limited
  exceptions, combatants may be made the object of attack at all times, regardless of the activities in which
  they are engaged. For example, enemy combatants who are standing in a mess line, engaging in recreational
  activities, or sleeping remain the lawful object of attack. Exceptions include personnel who are hors de
  combat (see paragraphs 2-106 through 2-116) and provisions for communication with the enemy and special
  agreements with the enemy (see Chapter 7).
  CATEGORIES OF PERSONS WHO ARE COMBATANTS FOR THE PURPOSE OF ASSESSING
  THEIR LIABILITY TO ATTACK
  For the purpose of assessing liability to attack, the following categories of persons are enemy
  combatants who may be made the object of attack based on their affiliation with armed forces or armed
  groups:
  * Members of the armed forces of a State and members of the regular armed forces of a government
  or authority not recognized, except for full-time medical and religious personnel;
  * Members of militia and volunteer corps;
