How to Use This Calculator
- Select obstacle type: Wire, Minefield, Ditch/Trench, Concrete Barrier, or Abatis.
- Enter obstacle width (m) and depth/height (m) to calculate breach material requirements.
- Set the number of lanes required for the breach based on unit size and traffic flow.
- Enter personnel count to size the breach team and calculate labor-hours.
- Review breaching time estimate and material requirements to synchronize with fire support and maneuver.
How the result changes with Lanes Required
| Lanes Required | Total Breach Time |
|---|---|
| 1.9 | 60 min |
| 4.15 | 132 min |
| 6.85 | 218 min |
| 9.1 | 290 min |
