Fire Mission Calculator
Mortar Operations
- Position mortars on stable, level ground for best accuracy
- Maintain 360-degree firing capability when possible
- Establish clear communication with forward observers
- Use protective positions to avoid counter-battery fire
- Coordinate with friendly units to prevent fratricide
- Monitor ammunition supply and resupply routes
- Employ proper camouflage and concealment techniques
- Designate primary and alternate firing positions
Grid Coordinate System
- Arma Reforger uses a 6-digit grid coordinate system
- Each grid square represents 100 meters x 100 meters
- X-coordinate represents eastward movement
- Y-coordinate represents northward movement
- Precision increases with additional digits
- Use map protractor for precise measurements
- Account for magnetic declination when available
- Verify coordinates through multiple sources

Fire Mission Procedures
- Receive target coordinates from forward observer
- Calculate azimuth and range using map coordinates
- Determine appropriate charge and elevation settings
- Prepare ammunition with correct charge rings
- Set mortar azimuth using compass bearing
- Adjust elevation according to ballistics table
- Fire adjustment rounds as needed
- Execute fire for effect when on target
Safety Protocols
- Maintain minimum safe distances from friendly forces
- Verify target identification before firing
- Use proper hearing protection during operations
- Handle ammunition according to safety procedures
- Clear firing areas of personnel before shooting
- Monitor for misfires and unexploded ordnance
- Establish clear fields of fire and impact areas
- Coordinate with air traffic when applicable
Target Types and Effects
- Personnel in open: HE rounds with airburst fusing
- Fortified positions: HE rounds with direct impact
- Vehicle columns: HE rounds with timed spacing
- Area denial: WP rounds for screening
- Night operations: Illumination rounds for visibility
- Smoke screening: Smoke rounds for concealment
- Suppression missions: Sustained HE bombardment
- Harassment fire: Random timing and spacing
Professional Tip
For maximum accuracy, use triangulation to determine your exact mortar position on the map. Place landmarks on known positions and use bearing lines to find the intersection point where your mortar is located. This eliminates position errors that can cause significant miss distances.
Advanced Technique
When engaging targets at maximum range, consider meteorological conditions such as wind speed and direction. High-angle fires are more susceptible to wind drift, so adjust your azimuth accordingly. Use registration points to verify accuracy before engaging primary targets.
