How to Use This Calculator
  1. Select obstacle type: Wire, Minefield, Ditch/Trench, Concrete Barrier, or Abatis.
  2. Enter obstacle width (m) and depth/height (m) to calculate breach material requirements.
  3. Set the number of lanes required for the breach based on unit size and traffic flow.
  4. Enter personnel count to size the breach team and calculate labor-hours.
  5. Review breaching time estimate and material requirements to synchronize with fire support and maneuver.

What each input means

Obstacle Type
Type of obstacle to be breached.
Obstacle Width
Width (depth into the obstacle belt) to breach through.
Obstacle Depth/Height
Height or depth of the obstacle.
Lanes Required
Number of breach lanes to create.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Obstacle Type = 0, Obstacle Width = 15, Obstacle Depth/Height = 1.5, Lanes Required = 2 = 6 input(s) provided
  2. Calculate Total Breach Time
    Total Breach Time
    64 = 64
  3. Calculate Time per Lane
    Time per Lane
    32 = 32
  4. Calculate Bangalore Torpedoes
    Bangalore Torpedoes
    6 = 6
