Mortar calculator
Tap where your mortar is, then tap the target. You get distance, bearing and how much higher or lower the target sits.
Bearing is measured clockwise from the top of the map (0° up, 90° right), in degrees and in 6400-mil. Heights come from the game's terrain, sampled every 4 m around the fight area. They are accurate to about 2 m; outside that square the height shows as off grid. The last five targets stay in the table so a crew can work through them. Elevation will appear here once we've range-tested the L81.
