Methods

We began with critical incident studies of recent urban operations including the Tet offensive in Hue City, Vietnam 1968; the US experience in Mogadishu on October 3rd, 1993 during the Somalian Civil War; the battles for Grozny and Chechnya in 1995 and 1996; and the 2002 Israeli operation in Jenin, West Bank. This provided us a broad corpus of cases spanning decades which depicts the nature of battle on urban terrain and the typical responses by Western forces to engage in these battles.

To complement these case studies we participated in debriefings of units returning from urban operations in the Balkans, Afghanistan and Iraq, as well as observation of U.S. Military training exercises. What's interesting about many of these cases is the extent to which the under-powered, under-manned, and under-coordinated forces won decisive victories over vastly overpowering adversaries. These crushing defeats are a testament to the fact that the urban environment offers numerous surprises and characteristics that give tremendous advantage to those who know the terrain well enough to exploit it.

  We synthesized the available CTA results across these multiple sources. Critical functions needing support in urban operations that may be relevant to new sensor technologies include:
  • Orientation to the environment and friendly forces (e.g., the danger of getting lost in urban environments and the need to cross reference landmarks, targets, and locations across units and echelons; the need to coordinate unit boundaries as local terrain makes this difficult and effective asymmetric foes try exploit them).

  • Restrict opponent's mobility (e.g., cutting off routes of escape & approach, sealing off areas).

  • Managing civilians in potential conflict areas as there is a complex mix of hostile and civilian populations (e.g., avoid alienating local populace; detecting when civilians are being used by opponents such as bait and trap).
Complicating factors in the urban environment that need to be considered in any human-technology design include:
  • Urban terrain changes and is re-designable.

  • Different operational tempos in different parts of the cityscape can cause mis-synchronization across units.

  • Speed of decisions and situations can change unpredictably across high intensity, low intensity, crowd control, humanitarian situations.

  • Varying rules of engagement and opponents who fight your rules of engagement.

  • Vertical multi-tiered environment.

  • Highly adaptive situations against fast-learning adversaries.

  • Operations can be channeled along narrow lanes due to limited fields of view, limited fields of fire, and constricted avenues of approach.

  • Risk of friendly fire is high. Difficult resource management tasks as urban operations burn through people and other resources rapidly.
