What is the Mortar Calculator Arma Reforger?
The mortar calculator arma reforger is an essential tactical tool designed for players who want to provide accurate indirect fire support in the realistic military simulation environment of Arma Reforger. Unlike traditional shooters where aiming is intuitive, the mortar calculator arma reforger utilizes complex ballistics physics to determine exactly where a projectile will land based on its initial velocity, gravity, and target coordinates.
Who should use it? Primarily, squad-level fire support teams and dedicated mortar crews who need to strike targets without a direct line of sight. A common misconception about the mortar calculator arma reforger is that it is a “cheat.” In reality, it mimics the real-life fire direction centers (FDC) that actual artillery units use to calculate firing solutions in the field.
Mortar Calculator Arma Reforger Formula and Mathematical Explanation
The math behind the mortar calculator arma reforger relies on the standard equations for projectile motion. In Arma Reforger, we must solve for the firing angle (elevation) to reach a specific coordinate (X, Y) with a specific altitude difference.
The fundamental formula for the firing angle θ is:
θ = arctan((v² ± √(v⁴ – g(gD² + 2ΔHv²))) / gD)
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| v | Muzzle Velocity | m/s | 70 – 240 |
| g | Gravity | m/s² | 9.81 |
| D | Horizontal Distance | Meters | 50 – 4000 |
| ΔH | Altitude Difference | Meters | -500 – 500 |
| θ | Firing Angle | Mils | 800 – 1500 |
Practical Examples (Real-World Use Cases)
Example 1: The Mountain Ridge Strike
Suppose you are using the mortar calculator arma reforger at coordinates (1200, 1200) at an altitude of 100m. Your target is an enemy radio tower at (1600, 1600) at an altitude of 250m. Using Charge 1, the calculator determines the distance is 565.7 meters. Due to the high altitude of the target (+150m), the mortar calculator arma reforger will suggest a lower mil elevation to ensure the shell clears the distance and impacts higher up.
Example 2: Suppression of a Valley Village
In this scenario, your mortar is at (2000, 2000) alt 300m, and the target is at (2000, 3000) alt 50m. The distance is exactly 1000m. Because the target is significantly lower (-250m), the mortar calculator arma reforger will adjust the trajectory to a steeper arc, resulting in a higher mil count for elevation to prevent overshooting the village.
How to Use This Mortar Calculator Arma Reforger
To get the most out of your mortar calculator arma reforger, follow these simple steps:
- Open your in-game map and identify your current coordinates (X and Y) and your altitude.
- Identify your target’s coordinates and altitude.
- Enter these values into the mortar calculator arma reforger input fields.
- Select the appropriate charge. Charge 0 is for very close targets, Charge 1 is for medium range, and Charge 2 is for long-range suppression.
- Read the “Elevation” result in mils. Adjust your mortar’s handwheel until the in-game display matches this number.
- Read the “Azimuth” and rotate your mortar to the correct bearing.
Key Factors That Affect Mortar Calculator Arma Reforger Results
- Muzzle Velocity: Each charge level provides a different velocity. Using the wrong charge in your mortar calculator arma reforger will result in a total miss.
- Gravity: While fixed at 9.81 m/s², it is the primary force pulling your shell down.
- Altitude Difference: Shooting uphill or downhill drastically changes the required angle. The mortar calculator arma reforger accounts for this ΔH automatically.
- Windage: Currently, Arma Reforger has simplified wind, but in advanced simulations, crosswinds can push your shell off course.
- Dispersion (CEP): No mortar is 100% accurate. Even with the perfect mortar calculator arma reforger solution, shells will land in a small circular error probable area.
- Air Resistance: Drag slows the shell down over time. Our mortar calculator arma reforger uses a model that approximates the game’s internal ballistics.
Frequently Asked Questions (FAQ)
This means that even at the most optimal firing angle (45 degrees), the selected charge cannot push the shell far enough to reach the target. Switch to a higher charge in the mortar calculator arma reforger.
Milliradians (Mils) are a unit of angular measurement used by militaries. There are 6400 mils in a circle, providing much finer precision than 360 degrees for long-distance fire support.
Yes. Because the mortar must be fired at a high angle, there is a limit to how close it can hit. Usually, this is around 50-100 meters depending on the charge.
Look for the contour lines on your map. In Arma Reforger, these lines represent height increments. Most mortar calculator arma reforger users estimate based on the nearest elevation marker.
While the mechanics are similar, the 82mm and 81mm mortars have slightly different range tables. This mortar calculator arma reforger is optimized for the standard 82mm found in game.
Depending on the charge, they travel between 70 m/s and 240 m/s. Flight times can vary from 15 to over 40 seconds.
Yes, the mortar calculator arma reforger is specifically designed to handle the ballistic profiles used by the Podnos mortar system.
Check if you were firing from a level surface. If the mortar itself is tilted, the internal leveling of the weapon might be offset.
