Vanilla Arma Reforger mortar
2B14 Mortar Calculator for Arma Reforger
The 2B14 is the other vanilla mortar in Arma Reforger, and it is not computed like the M252: its azimuth runs on the 6000 mil scale and the operator setting is a charge number. Reforger FDC keeps the two scales apart and gives the 2B14 its own numbers.
- Operator setting
- Charge 4
- Azimuth
- 597 mil
- Elevation setting
- 976 mil
- Time of flight
- 28.7 s
A solution read off the app, not an example: Everon, gun at X4922 Y4868 and 89 m, target at X6100 Y6500 and 167 m. Range 2013 m, height difference +78 m, high trajectory, 6000 mils per circle.

What the calculator computes for the 2B14
It takes range and azimuth from the two points, picks a charge that covers the range, and returns the elevation and the time of flight. Where charges overlap, the other solutions sit next to the recommended one. Choosing between them is a trade: at 500 metres charge zero arrives in about 12 seconds and charge four in about 33, while the higher charge changes elevation more slowly with range, so a range error hurts less.
Gun and target heights are read from the map terrain and the difference is applied to the elevation. The correction is derived from the shape of the table itself and was confirmed in game on 31 August 2026; the column once taken for a height coefficient plays no part in it. Where the angle of fall is below five degrees the application refuses to compute the correction and says so rather than substituting a plainly wrong number. The 2B14 tables carry wind coefficients; where a direction and range are not covered, the application says so and leaves the solution without a wind correction rather than substituting a plausible number.
Things that catch people out
- The 6000 mil scale. An azimuth taken from the M252, or from any calculator working in 6400, is wrong here: the gap grows with the azimuth and reaches several hundred mils in the rear arc.
- Smoke stops at 1700 metres, well short of the high explosive round. A distant target that the HE table covers may not be reachable with smoke at all.
- Illumination has no charge zero; it starts at charge one.
- The table here is the vanilla one. A mod such as Adult Mortars rewrites ranges, dispersion and even how many rings the smoke round takes, and on a server running it these numbers fit no range at all. The sources page shows what changes.
The same target from three mortars
The readouts on the mortar pages of this site are taken from one Everon position, gun at X4922 Y4868 and target at X6100 Y6500, 2013 metres away and 78 metres higher, so they can be laid side by side.
- M252
- 4 rings, azimuth 637 mil, elevation 1204 mil, 33.9 s
- 2B14
- charge 4, azimuth 597 mil, elevation 976 mil, 28.7 s
- 2B9 Vasilek
- long-range charge, low arc, azimuth 597 mil, elevation 194 mil, 9.0 s
The azimuths are the same bearing written on two scales: 637 of 6400 and 597 of 6000 point the same way. Carry 637 over to the 2B14 and the round lands about 40 mils off to the side, roughly 80 metres at this range. Elevation and time of flight differ because the tables differ, and the Vasilek's low arc is a different kind of shot altogether.
How to open the 2B14 in the application
- Open Reforger FDC with this gun already selected and choose the map workflow or the coordinate one.
- Check that the weapon block shows the 2B14, then pick the projectile you need.
- Place the gun point and the target point; heights come from the terrain.
- Read the charge, azimuth, elevation and time of flight, then mark the impact to get a correction.
