Rogue Division Indirect fire means lobbing a shell over cover onto a target you may never see.
Three numbers matter: bearing (which way to traverse), elevation (how steeply to
angle the tube), and flight time (how long until impact).
Getting a bearing
Bearing is compass degrees clockwise from north. 0° is due north, 90° east, 180° south,
270° west. Apollyon's WARDOGS Artillery Calculator works this out from two grid references (real Bakurani terrain to click positions on — the same art, credited the same way, on our own Strat Vault), so you only need to read your own position and the target's.
Why elevation has two answers
For any reachable target there are two launch angles that land a shell on it: a low, flat
arc and a high, lobbed arc. They always add up to about 90° on flat ground — a target
at 3,000 m with a 240 m/s shell can be hit at either 15.3° or 74.7°.
Mortars use the high arc. It clears terrain, comes down steeply into trenches and behind
walls, and is far less affected by a small error in range. The tool always returns the high
arc for that reason.
Height difference
A target above you needs a slightly different angle than one on your level. Enter altitudes
for both positions and the tool accounts for it. Firing at a target higher than the tube
brings the two arcs closer together and shortens your maximum range; firing downhill extends it.
Mils versus degrees
Gunnery often uses mils rather than degrees: 6,400 mils to a full circle, so one mil is
a hair under 0.06°. Mils are finer-grained, which is why sights use them. The tool shows
both.
What the numbers are worth right now
The elevation figure is computed from projectile motion without air resistance, using a
muzzle velocity that is currently a community placeholder rather than confirmed game data.
Treat it as a first-round estimate, spot the fall of shot, and adjust.
The moment anyone measures a real range table in game — range in, elevation observed — enter
it and the tool will use those measurements instead of the model. That is the single most
useful thing you can contribute to this site.
