  other components of its combat power. Information has become a vital strate-
  gic and operational resource. The OPFOR clearly understands the power of
  information and the revolution in IT and is actively developing doctrine and
  tactics to supplement more traditional types of warfighting. The OPFOR can
  use IW activities to create and/or exploit windows of opportunity for itself.
  5-3. The importance of information, and its flow and control, to the conduct of
  military operations is not a new concept. The OPFOR has for years employed an
  integrated approach to attacking, disrupting, or manipulating information inside
  the enemy’s decision-making cycle. Objectives have included not only the sys-
  tems and information its enemies collect, process, and analyze, but also the leaders
  and the decisions they make. What is new, however, is the speed and volume of
  information available; networking, routing, and switching technologies; and the
  global connectivity of information systems and infrastructures. This information
  explosion, coupled with an integrated IW doctrine, provides the OPFOR a
  greater opportunity to inflict damage, trigger chaos, weaken national will, or
  permanently cripple an opponent. In effect, IW challenges traditional approaches
  to warfare. The following are ways in which IW redefines operations.
  INFORMATION INFRASTRUCTURE
  5-4. Most of today’s information environment is outside of military control,
  making it harder to regulate, dominate, or protect. While neither the State
  nor its opponents can control the global information environment or global
  information infrastructure (GII), they must prepare to operate within it. The
  GII is defined as the worldwide interconnection of communications networks,
  computers, databases, and consumer electronics that make vast amounts of
  information available to users. Within the GII, various countries have their
  own national information infrastructures (NIIs) and defense information
  infrastructures (DIIs).
  5-5. The NII is the physical and virtual backbone of a nation. It is composed
  of multiple critical infrastructures. Critical infrastructures are those in-
  formation and communication assets, systems, and functions so vital to a
  nation that their disruption or destruction would have a debilitating effect
  on national security, economy, governance, public health and safety, and morale.
  5-6. The DII is defined as the shared or interconnected system of computers,
  communications, data applications, security, people, training, and other sup-
  port structures serving an actor’s defense needs. The DII connects computers
  used for mission support, command and control (C2), and intelligence through
  voice, telecommunications, imagery, video, and multimedia services.
  5-7. The interaction of the GII, NIIs, and DIIs introduces multiple actors into
  the information environment. This increases vulnerabilities and dependen-
  cies, and creates many legal issues.
  BLURRED BOUNDARIES
  5-8. The OPFOR understands that there is no clear-cut line of demarcation
  between the military, economic, and diplomatic-political aspects of an opera-
  tion or strategic campaign and that the informational element cuts across the
  other three. Therefore, it uses all types of IW across all these dimensions.
