  Table 18-1. Breaching tenets
  Breaching Tenets Actions
  Intelligence Template enemy obstacles on the SITEMP for each enemy COA during IPB based
  on—
  • The enemy ability to emplace obstacles based on its capabilities (manpower,
  equipment, and materials) and time available.
  • The effects of terrain and weather.
  • The range of enemy weapon systems covering obstacles and emplacing
  scatterable mines.
  Develop information requirements on enemy engineer units, equipment, activities,
  and obstacles (location, composition, and mine types).
  Integrate information requirements and engineer reconnaissance capabilities into
  the information collection plan.
  Breaching Implement fire control measures to allow the support force to provide effective
  fundamentals direct and indirect suppressive fires (suppress).
  (SOSRA) Determine the placement (wind condition), density, and timing of placing
  obscurants on enemy positions and placing screening obscuration between the
  enemy and the reduction area (obscure).
  Resource the breach force based on the combat power of enemy forces
  overwatching the obstacle (secure).
  Determine the number and width of lanes based on the scheme of movement and
  maneuver (one lane per company and two lanes per battalion), determine
  reduction methods (explosive, mechanical, or physical), and establish a lane
  marking system (reduce).
  Complete the breach by destroying the enemy on the far side of the obstacle
  (assault).
  Breaching Suppress enemy direct fire and observed indirect fires on the reduction area
  organization (support force).
  Control indirect fires and indirect fire obscuration within the breach area (support
  force).
  Prevent the enemy from repositioning or counterattacking to place direct fires on
  breach force (support force).
  Create and mark lanes for the breach element (breach force).
  Secure the obstacle near side and far side for the security element (breach force).
  Report lane status and location (breach force).
  Assault through the obstacle and destroy the enemy on the far side (assault force).
  Mass Mass effects to create enemy weakness at the POB.
  Prevent enemy from massing effects at the POB.
  Synchronization Conduct detailed reverse planning.
  Communicate clear instructions to subordinate units.
  Provide effective command and control.
  Perform combined arms rehearsals.

  18-24. Suppressive fires in sufficient volume serve to secure the reduction area. The purpose of suppression
  during breaching is to protect forces reducing obstacles and maneuvering through the reduction area.
