Summary
A working M18 FADAC artillery computer and the fire direction center to run it from. Manaul is in the Artsenal, the FDC bunker and M18 is GM Placeable only.
Official Workshop description
Artillery in Arma Reforger is pointed. This mod is about computing.
Build a US fire direction center, sit down at an M18 FADAC gun direction
computer, and work real fire missions — take the call from your forward
observer, key it in, and read out the firing solution.
THE M18 FADAC
A fully operable console, not a prop. Walk up, power it on, and the panel
opens as a full-screen instrument you actually operate:
- A 24-key panel keyboard, worked by hand
- Four numeric readouts and eighteen indicator lamps
- Four gun lines, A through D
- Four fire mission slots, A through D, each holding a stored target
- Grid, polar and shift missions
- Subsequent corrections — LEFT/RIGHT, ADD/DROP, UP/DOWN
- Charge selection, including the lowest charge that will reach
- A numbered fault code set for bad entries, out-of-range targets
and sequence errors
Missions are weapon-agnostic and stored independently of the guns, so a
target plotted for 81mm can be re-shot later with something heavier
without re-entering it.
The console reads as live hardware from outside, too. The lamps and
readouts are real emissive geometry on the model, so anyone in the room
can see which slots are loaded and which gun line is up — not just the
operator.
THE BUNKER
A sandbagged, timber-roofed fire direction center, furnished as a working
command post: desks, map boards, field telephone, lanterns, filing
cabinets, and the FADAC on its stand. Placed as one piece.
PLACEMENT
Both the bunker and the console can be placed individually through the
Game Master entity browser, under the US faction.
ROADMAP
This release is the FADAC and the bunker it lives in. Still to come:
- The operator's manuals as an in-game item
- An RTO station
- AN/TPS-25 medium-range radar
- A counter-battery radar
Feedback on the console is welcome and will shape the rest of it.

-in this build the M18 FADAC should work in multiplayer. I had messed up the Ballistic table and math for the M18 FADAC which resulted in it incorrectly thinking the max range was 2900? I stupidly believed my own scripts than double checking like a dork. The BIG issue was replication. Alot of the functions are supposed to be handed over to the server so a new operator can see the same work that the previous operator worked on and that handoff wasnt working. Should be fixed as of 0.9.8. Special thanks to the Fellas at EOH_MACV for letting me nuke their test server to test my ballistics computer xDconfig.json entry
