How to Use This Calculator
- Select position type: Hasty Fighting Position, Deliberate Fighting Position, Machine Gun Position, Vehicle Position, or Command Post.
- Enter the number of positions to construct.
- Select soil type (Sandy, Loam, or Clay) which affects digging time and material requirements.
- Review sandbag count, material weights, and labor hours needed for the position set.
- Use these figures to task engineer assets and pre-stage construction materials.
How the result changes with Number of Positions
