How to Use the Foxhole Artillery Calculator

In Foxhole, mastering artillery like the 120mm Light Artillery or the massive 150mm Heavy Artillery requires compensating for wind drift. This calculator helps you determine the exact distance and azimuth adjustments needed to ensure your shells land on target every time.

Step-by-Step Instructions:

1. Identify Target: Use a pair of Binoculars to find the distance and azimuth from your gun to the target.
2. Check Wind: Look at flags, smoke, or a wind vane. Foxhole wind has 5 strengths (Tiers). For 120mm guns, each tier is roughly 10 meters of drift.
3. Input Data: Enter your binocular readings and the wind direction (the direction the wind is blowing towards).
4. Adjust Your Piece: Set your artillery piece to the "Firing Coordinates" provided by the calculator.

Example Calculation

If your target is at 150m with an azimuth of 45°, and you have a Tier 3 wind blowing North (0°) with a strength of roughly 30m:

• Input Distance: 150
• Input Azimuth: 45
• Wind Strength: 30
• Wind Direction: 0

The calculator will tell you to fire at a shorter distance and adjusted angle to "fight" the wind that would otherwise push your shell past the target.

Understanding Wind Tiers

Wind Tier	120mm Offset (Approx)	150mm Offset (Approx)
Tier 1	10m	15m
Tier 3	30m	45m
Tier 5	50m	75m

Note: Always perform a spotting shot (test fire) before committing a full battery barrage. Accuracy is affected by spread, and wind can shift during long engagements.
