Informal War.
Informal war is armed conflict where at least one of the
antagonists is a nonstate entity such as an insurgent army
or ethnic militia. Twenty-first century informal war will be
based on some combination of ethnicity, race, regionalism,
economics, personality, and ideology. Informal war will both
be more common and more strategically significant. Combat
in future informal war is likely to remain “hands on,” pitting
the combatants in close combat. Warriors will be interspersed
among noncombatants, using them as shields and
bargaining chips. At times, refugee disasters will be
deliberately stoked and sustained to attract outside
attention and intervention. Unlike formal war, informal
war will remain dirty and bloody.
Some types of informal war will be comparatively
simple. Counterinsurgency, which uses military forces to
attain not only the short-term restoration of order but also
ultimate resolution of the conflict that led to disorder in the
first place, is a different and more difficult matter. There is
no doctrine or strategy for dealing with networked
opponents, be they existing criminal cartels or future
insurgents. To be successful against future insurgents, the
U.S. military will need better intelligence, better force
protection, and greater precision at the tactical and
strategic levels. In part, these things require new
organizational methods. Emerging technology also holds
promise. Again, nonlethal weapons and robotics may prove
the most vital.
