Support Specials And Tactical Modules Atlas

Support Specials And Tactical Modules Atlas

This atlas maps support calls, specials and tactical modules: paratroopers, paradrops, UAV, artillery, ICBM/Nuke, MASH, airlift/ZetaCargo, service actions and supply mission hooks.

Tactical Menu Entry Points

The main support UI is Client/GUI/GUI_Menu_Tactical.sqf.

Key source refs:

• GUI_Menu_Tactical.sqf:58-61 defines support list/fees/cooldowns.
• :146-217 owns fast-travel destination discovery, fee-mode filtering and local fee marker text.
• :252-282 gates support buttons by funds, upgrade level and local cooldown state.
• :403-406 locally debits paid fast travel after destination click.
• :371-373, :513-527 send RequestSpecial support requests.
• :463-505 performs the ICBM local launch flow.
• :532-605 requests artillery/fire mission behavior.

Server dispatch starts at Server/PVFunctions/RequestSpecial.sqf:1, which forwards directly into Server/Functions/Server_HandleSpecial.sqf. The server dispatch file handles paratroops/ammo/vehicle/UAV around :43-64, ICBM around :97-111, and repair-camp behavior around :147-170.

RequestSpecial scout 2026-06-04: the active tag set in source Chernarus is update-teamleader, group-query, Paratroops, ParaVehi, ParaAmmo, RespawnST, uav, upgrade-sync, update-clientfps, update-town-delegation, ICBM, process-killed-hq, connected-hc and repair-camp. track-playerobject has a server switch case around Server_HandleSpecial.sqf:133-145, but no active Chernarus RequestSpecial caller was found; treat it as an undriven bookkeeping branch unless a later dynamic caller proves otherwise.

Depth scout follow-up 2026-06-04 added one high-value authority caution: group-query is not just a harmless request relay. Server_HandleSpecial.sqf:13-31 trusts payload _group, _player and _side; if the target leader is AI and the group lacks wfbe_uid, it calls Common_ChangeUnitGroup.sqf:3-11 to move the payload player into that group. Patch this in the server-authority lane by deriving requester/player/side server-side before any group move.

Mini-scout follow-up 2026-06-04 tightened the authority map:

• Tactical menu gating is client-side first: Client/GUI/GUI_Menu_Tactical.sqf:252-283,293-347,463-527 checks funds, upgrades, commander status, UAV state and local cooldowns before requests are sent.
• Artillery is not a RequestSpecial asset-spawn path. Client_RequestFireMission.sqf:50-72, Common_HandleArtillery.sqf:7-85 and Common_FireArtillery.sqf:7-72 own local cooldown/fire-control/range behavior, with ammo options loaded through Common_GetArtilleryAmmoOptions.sqf:41-72 and Common_LoadArtilleryAmmo.sqf:18-53.
• UAV is client-spawned and client-paid in Client/Module/UAV/uav.sqf:15-52; Server/Support/Support_UAV.sqf:6-20 mainly monitors and cleans it up.
• Server_HandleSpecial.sqf:67-74 has a fragile upgrade-sync branch: it reads _side from _args select 1, then _upgrade_id / _upgrade_level from _this select 2/3. Any caller-shape change can break that branch differently from the other RequestSpecial tags.

Upgrade-Sync Branch Matrix

upgrade-sync is consistency/cleanup debt rather than a proven current runtime break: Server_HandleSpecial.sqf:3 sets _args = _this, so today's mixed _args / _this reads resolve to the same payload. The cleanup is still patch-ready because it makes the RequestSpecial tuple contract explicit before broader router hardening.

Root / branch	Evidence	Status
Current source Chernarus	Server_HandleSpecial.sqf:3,67-73 assigns _args = _this, reads _side from _args select 1, then _upgrade_id / _upgrade_level from _this select 2/3; GUI_UpgradeMenu.sqf:241 sends ["upgrade-sync", WFBE_Client_SideJoined, _this select 0, _this select 1]; Server_ProcessUpgrade.sqf:26,29,35 owns the sync variable.	Mixed-source reads remain; current behavior is equivalent but fragile.
Maintained Vanilla Takistan	Same maintained-root shape in Server_HandleSpecial.sqf:3,67-73, GUI_UpgradeMenu.sqf:241 and Server_ProcessUpgrade.sqf:26,29,35.	Needs the same cleanup if source is patched.
Stable origin/master 2cdf5fb8	Same mixed _args / _this branch in both maintained roots; caller line GUI_UpgradeMenu.sqf:241.	No stable-master rescue.
Miksuu upstream f532f706	Same mixed branch and caller tuple in both maintained roots.	No upstream rescue.
origin/perf/quick-wins 0076040f	Same mixed branch and caller tuple in both maintained roots.	Perf branch does not touch this router path.
Release origin/release/2026-06-feature-bundle d482c742	Same mixed branch in both maintained roots; release Chernarus caller shifted to GUI_UpgradeMenu.sqf:254, Vanilla remains :241. The new release head has no relevant diff from the earlier 3282ff3f smoke harness head.	No release rescue; only Chernarus line drift.

Patch order: normalize the branch to read side/id/level from _args only, add a short tuple comment or helper-local guard if editing the router, keep RequestUpgrade authority migration separate, propagate maintained Vanilla, then smoke normal commander upgrade completion, non-server client timer sync, malformed/short payload rejection and AI commander upgrade progress.

Support-authority scout 2026-06-04 sharpened the non-ICBM payload-trust cases:

• Paratrooper support passes payload _playerTeam into Support_Paratroopers.sqf; the dropped infantry are created into that team and the marker callback targets leader _playerTeam. A forged or stale team payload is therefore not just a notification issue.
• RespawnST is called from GUI_Menu_Economy.sqf:91-96 with sideJoined, while Server_HandleSpecial.sqf:55-60 trusts the payload side and damages every current wfbe_ai_supplytrucks entry for that side. Treat wrong-side forged respawn requests as part of the non-ICBM support authority lane.
• Camp repair action scripts send ["repair-camp", _camp, WFBE_Client_SideID]; Server_HandleSpecial.sqf:147-168 trusts the camp object and repair-side payload when changing camp sideID and broadcasting CampCaptured.
• Old UAV cleanup is server-observed but client-created/client-paid: Client/Module/UAV/uav.sqf:27-52 owns spawn/debit, and Support_UAV.sqf:6-20 mainly tracks/cleans the payload object.

No live RequestSupport symbol was found in source Chernarus during the 2026-06-04 trigger-chain scout; support and special effects route through RequestSpecial.

Transport split from the 2026-06-04 supports scout:

• Registered support requests use the generic PVF envelope: Common/Functions/Common_SendToServer.sqf:12-18 prepends the function tag, Server/Functions/Server_HandlePVF.sqf:9-14 dispatches it, and Server/PVFunctions/RequestSpecial.sqf:1 delegates into Server_HandleSpecial.sqf.
• Client-bound support feedback uses the sibling path: Common/Functions/Common_SendToClient.sqf:9-18 and Client/Functions/Client_HandlePVF.sqf:19-22.
• Artillery is not the same server-accepted support path. Client/GUI/GUI_Menu_Tactical.sqf:531-547 gates fire missions locally, Common_GetTeamArtillery.sqf:10-30 discovers usable guns from the caller's group units, Client/Functions/Client_RequestFireMission.sqf:13-31,51-54 starts local fire/cooldown behavior, and Common/Functions/Common_FireArtillery.sqf:9-23,53-72 validates gun/range/firing mechanics. The 2026-06-04 source patch makes manned artillery-class base-area defenses use the current commander team when one exists (Construction_StationaryDefense.sqf:91-94), so commander-built HQ/base ARTY can become visible to this group-based fire-mission path. Smoke that ownership separately from ARTY setup in Arma 2 OA.
• Service actions are another local support family. Client/GUI/GUI_Menu_Service.sqf:196-234 debits/spawns rearm/refuel/repair/heal support locally; Service menu affordability guards owns the small local correctness patch, while full authority remains an economy-ledger redesign.

Adjacent server runtime surfaces: grouped base areas are enabled only when WFBE_C_BASE_AREA > 0 (Server/Init/Init_Server.sqf:565). Side logic seeds wfbe_basearea at Init_Server.sqf:380; Server/FSM/basearea.sqf:46-80 then polls every 20 seconds, prunes invalid/remote base-area logics, and schedules delayed orphan-defense cleanup through _onAreaRemoved (basearea.sqf:12-43). Server/FSM/groupsMonitor.sqf:1-14 is a dormant debug monitor that logs allGroups counts every 30 seconds; its only source start point found in this pass is commented at Init_Server.sqf:567.

Support Feature Matrix

Feature	Status	Notes
Tactical support menu	Partial	UI works, but most fee/cooldown/upgrade gates are client-side only.
Fast travel	Working/partial	Local Tactical flow. Fee mode hides unaffordable towns and debits locally; branch/root matrix and UX decision live in Client UI systems.
Paratroopers	Working/partial	RequestSpecial -> HandleSpecial -> KAT_Paratroopers; server creates transport/units and sends marker callback. Missing server-side fee/cooldown/upgrade validation.
Ammo paradrop	Working/partial	Client-gated by WFBE_UP_SUPPLYPARADROP and shared lastSupplyCall; server creates aircraft/crates.
Vehicle paradrop	Working/partial	Similar to ammo paradrop; server creates cargo vehicle and empty-vehicle cleanup.
UAV	Partial	Client creates UAV, deducts funds and sends tracking request; server mostly monitors cleanup and reveal broadcasts.
Artillery	Working/partial	Local/client fire authority with upgrade-gated UI/ammo/timeout behavior.
Anti-air radar (AAR)	Working/partial	Base structure and client marker feature are live when enabled; upgrade levels change marker detail and refresh rate, but the per-aircraft marker loops are client-local and should be performance-smoked on busy air games.
ICBM/Nuke	Partial/high-risk	Client deducts funds and sends RequestSpecial ["ICBM", ...]; server applies nuke damage from payload. Stale adjunct paths remain.
MASH	Partial/stale	Local officer deploy path supports respawn lookup, but marker sender/relay/receiver are split or disabled.
ZetaCargo/airlift	Broken/partial	Hook attaches nearby unmanned land vehicle; detach action does not pass the lifted vehicle even though unhook expects it.
Service menu	Working/partial	Repair/refuel/rearm/heal effects and deductions are client-side; local support scripts recheck world state but not full money authority.
Supply mission	Partial	Server validates return proximity but trusts client-set SupplyFromTown / SupplyAmount.
Supply truck respawn	Partial/unclear	Economy menu requests RequestSpecial ["RespawnST", sideJoined]; Server_HandleSpecial.sqf:55-60 trusts the payload side and damages current wfbe_ai_supplytrucks for that side, but actual recreation depends on the broken/config-gated UpdateSupplyTruck path.

Server Dispatch And PV Paths

RequestSpecial.sqf is intentionally tiny and forwards payloads. That makes Server_HandleSpecial.sqf the important hardening boundary. Today, several high-impact support effects rely on the client UI having already enforced role, upgrade, fee and cooldown.

Use Server authority migration map before adding public support features. Use ICBM authority for the nuke path specifically, because it has public-server blast radius.

Economy Cooldown And Upgrade Gates

The tactical UI keeps support fees and intervals locally. The scout observed support fee examples [0,75000,9500,3500,8500,0,12500,0,0] and intervals [0,1000,800,600,900,0,0,0,0]; paid fast travel uses the separate distance-based WFBE_C_GAMEPLAY_FAST_TRAVEL_PRICE_KM path. Button enabling checks funds/upgrades/cooldowns client-side; future patches should re-check the same facts on the server before spawning assets or applying map-wide effects.

Do not treat those UI checks as security boundaries. For paradrops, UAV and ICBM, the server router currently assumes the client already did role, upgrade, fee and cooldown filtering. For artillery and services, much of the effect/debit path is client-local. Public-server hardening should therefore separate:

• RequestSpecial server validation for server-spawned assets and map-wide effects.
• local correctness guards for service/EASA/artillery UI paths.
• a broader economy ledger decision for client-side funds/effects.

Module Deep Dives

Anti-Air Radar

AAR is a live base-support system, not only a historical changelog item. The build/action layer recognizes AARadar structures (RequestStructure.sqf:14; updateavailableactions.fsm:189-222), and unit init starts Common_AARadarMarkerUpdate.sqf for opposite-side aircraft when WFBE_C_STRUCTURES_ANTIAIRRADAR > 0 (Init_Unit.sqf:111-114). The marker loop hides work while the map is closed, requires an AAR in range, applies the configured detection altitude, and reads WFBE_UP_AAR to move from speed-only markers at 5 seconds to altitude at 3 seconds and aircraft type at 1 second (Common_AARadarMarkerUpdate.sqf:53-121). It also records PerformanceAuditAARMarkerScripts and aar_marker_update samples, so large-aircraft smoke should include map-open/map-closed performance.

UAV

Client/Module/UAV/* owns creation/cost/PV behavior, interface toggles and reveal broadcasts. The server monitors/trashes the UAV when the leader leaves or the UAV dies. Current authority is client-led for spawn/cost and server-led for cleanup tracking.

ICBM And Nuke

Client/Module/Nuke/* owns launch UI/marker/object flow and sends the special request. Client/FSM/updateclient.sqf:19-20 still registers an ICBM_launched event handler, but no current publisher was found. NukeIncoming PVF exists but the current launch path uses RequestSpecial.

MASH

Client/Module/Skill/* owns officer MASH/supply actions. MASH deploy creates local tent state used by respawn lookup. Marker sync is stale: the server relay exists, the client receiver compile is commented, and no maintained Chernarus/Vanilla sender was found. The 2026-06-05 branch recheck found the same orphaned relay shape on stable, Miksuu upstream and the current release branch; modded eden/lingor sender lines are drift, not maintained-marker proof. Use Respawn/death lifecycle for the live respawn split.

ZetaCargo Airlift

Client/Module/ZetaCargo/* defines lifters/types and hook/unhook behavior. Airlift action is gated by WFBE_UP_AIRLIFT, but the detach action does not pass the lifted vehicle while Zeta_Unhook.sqf expects it in action arguments.

Logistics Supports

Paradrops, service actions and supply missions overlap with economy authority:

• Paradrops are server-created assets but client-gated requests.
• Service actions perform local timed repair/rearm/refuel/heal support and client-side debits.
• Supply mission completion adds side supply server-side but trusts truck variables set from client mission start.

Use Supply mission authority cleanup, Service menu affordability guards and Economy authority first cut for implementation sequencing.

Aircraft Ordnance Guardrails

Current source has live ordnance guardrails, but they are not all equally active:

• Bomb distance restriction is live for Bo_FAB_250 and Bo_Mk82. Plane setup attaches HandleShootBombs (Common/Init/Init_Unit.sqf:118-121); the handler exits unless the ammo is one of those bomb classes, requires the local player as shooter, reads WFBE_C_GAMEPLAY_BOMBS_DISTANCE_RESTRICTION, checks cursorTarget, hints STR_WF_MESSAGE_BombDistanceRestriction and deletes the projectile when the target is beyond the configured distance (Common/Functions/Common_HandleShootBombs.sqf:15-30).
• Bomb altitude is config-present but runtime-dormant in that handler. Rsc/Parameters.hpp:284-288 exposes WFBE_C_GAMEPLAY_BOMBS_ALTITUDE, default 2000, but the altitude check/delete block in Common_HandleShootBombs.sqf:32-44 is commented out.
• Incoming missile range limiting is live when WFBE_C_GAMEPLAY_MISSILES_RANGE is non-zero. Non-man units get an incomingMissile handler (Common/Init/Init_Unit.sqf:125-128); Common_HandleIncomingMissile.sqf:9-21 deletes IR-lock missiles, with a dumb-bomb workaround, once they exceed the configured range.
• Terrain-masking missile blocking is live for tanks, cars and air units through a Fired handler (Common/Init/Init_Unit.sqf:207-212). Common_HandleShootMissiles.sqf:95-140 detects guided missile-like ammo, uses cursorTarget, checks vehicle-to-target terrain intersection with ASL positions and deletes the projectile with STR_WF_MESSAGE_MissileTerrainMaskingRestriction plus MissileLaunchBlocked.
• The terrain-masking handler has a commented _limit_distance section (Common_HandleShootMissiles.sqf:107-117), so current enforcement is terrain-intersection based rather than "only under configured distance".
• Aircraft AA gating is partial/path-dependent. Build, buy, rearm and EASA paths remove/filter AA missiles through upgrade and parameter checks (Client_BuildUnit.sqf:287-293; Server_BuyUnit.sqf:155-162; Common_RearmVehicle.sqf:53-60; GUI_Menu_EASA.sqf:15-20), but start/pre-placed vehicles or unusual creation paths should be smoke-tested before claiming complete coverage.

The main risks are locality and player-facing false positives: bomb distance and missile masking lean on local cursorTarget, the unit init path exits for non-local player scope, and bomb altitude has a lobby parameter without active enforcement. Treat future aircraft-balance work as runtime-test-heavy, not just config editing.

Wave N Dispatch Notes

Wave N rechecked the support router and found two source-level traps worth keeping on this owner page:

• Server/PVFunctions/RequestSpecial.sqf:1 remains only a trampoline into HandleSpecial, so the actual authority boundary is Server/Functions/Server_HandleSpecial.sqf. That dispatch accepts paratroop/ammo/vehicle tags around :43-52, UAV around :63-64, ICBM around :97-111, track-playerobject around :133-146 and repair-camp around :147-170.
• RU para-ammo config is effectively commented out in Common/Config/Core_Root/Root_RU.sqf:36: the WFBE_%1PARAAMMO assignment appears after //--- Starting Vehicles on the same physical line. Server/Support/Support_ParaAmmo.sqf:59-60 exits unless WFBE_%1PARAAMMO is an array, so RU ammo paradrop support needs a config-line repair before it can be treated as feature-complete.
• Client/PVFunctions/NukeIncoming.sqf:7 plays airRaid, while Assets/config/localization/parameters atlas confirms no class airRaid in Sounds/description.ext. If NukeIncoming is revived, add or replace that sound reference.

Patch-Ready Hardening

Finding	Patch shape
RequestSpecial trusts client-side gates	Add server-side requester/side/role/funds/cooldown/upgrade validation before dispatching assets or map-wide effects.
Base-area cleanup private-list nit	If editing basearea.sqf, add _unit to the _onAreaRemoved private list before its static-gunner cleanup block. This is low-risk hygiene, not an urgent behavior bug.
Bomb altitude parameter is dormant	Either revive and smoke the commented altitude block in Common_HandleShootBombs.sqf, or rename/document the parameter as historical so admins do not expect it to enforce.
Ordnance guardrails depend on local target state	Test lock/no-lock, pilot/gunner, AI crew, JIP and remote locality cases before tightening bomb or missile restrictions.
AA missile gating is path-dependent	Verify start vehicles, purchased aircraft, client-built aircraft, rearmed aircraft, SAMs and EASA loadouts all pass the same WFBE_C_GAMEPLAY_AIR_AA_MISSILES / WFBE_UP_AIRAAM policy before calling AA restrictions complete.
RU ammo paradrop config is commented out	Split Root_RU.sqf:36 so the starting-vehicle comment does not swallow WFBE_%1PARAAMMO; smoke RU para-ammo request after the fix.
upgrade-sync mixed argument source	Use the upgrade-sync branch matrix. Normalize Server_HandleSpecial.sqf:67-74 to read side/id/level from one payload shape, then smoke upgrade completion synchronization.
Zeta detach missing vehicle arg	Pass [_vehicle] when adding the detach action in Zeta_Hook.sqf, or revise Zeta_Unhook.sqf to find the lifted object safely.
Stale ICBM adjuncts	Either wire the ICBM_launched / NukeIncoming paths intentionally or remove/document them as dead. If revived, fix the missing airRaid sound reference first.
MASH marker flow is split	Reconcile sender, server relay, client receiver, delete replay and JIP resend, or remove/archive the stale marker relay.
Supply mission cargo/source trust	Recompute cargo/source/reward server-side from trusted truck/town state.
UAV creation/cost client-owned	Move UAV spawn/cost validation server-side or validate requested type, side, funds and existing UAV before accepting tracking.

Validation Checklist

• Paratrooper, ammo and vehicle paradrops with valid/invalid upgrade levels and insufficient funds.
• UAV spawn, reveal, leader disconnect and cleanup.
• Artillery request with each upgrade level and local/remote gunner state.
• ICBM request from valid commander and forged/non-commander payload.
• MASH deploy, respawn availability and marker sync.
• Zeta hook/unhook with vehicle attached.
• Service actions with changing funds/world state between button enable and click.
• Supply mission cargo reward and cooldown after truck reuse.
