H-12: Improvised Obstacles

Previous: H-9: Demolition Obstacles

H-12. Improvised obstacles are designed by Soldiers and leaders with imagination and ingenuity when using available materiel and other resources. An example of obstacles in urban terrain is shown in figure H-3. Improvised obstacles include the following:

  • Rubble. Rubble from selected masonry structures and buildings in a built-up area will limit movement through an area and provide fortified fighting positions.
  • Battle damage. Damaged vehicle hulks or other debris are used as roadblocks.
  • Flooding. Flooded areas are created by opening floodgates or breaching levees.
