+## ⚠ `TurretClassID` is a RED HERRING — there is no turret code (2026-07-28) [T1]
+`engine/MUNGA/VDATA.h:209` really does declare `TurretClassID`, as the **last entry of the BT block**
+(right after `MechTechClassID`, before the ND section), which makes it look like a BattleTech class.
+It is not one. That enum position computes to **3038 = 0xBDE**, and 0xBDE in the shipped runtime is
+**ThermalSight** (ctor `@4b8718`, `thermalsight.cpp`, already DONE) — the same enum-vs-runtime label
+drift `CLASSMAP.md` records for HUD/MechTech at 0xBD6/0xBDC. The `case 0xbde:` in the mech factory
+(`part_012.c:10186`) is a **mech SUBSYSTEM** slot (roster `param_1[0x4a]`), not a world entity.
+Corroborating: there is **no `class Turret`** anywhere in the engine or the port, and `BTL4OPT.EXE`
+contains **zero** occurrences of `turret`/`sentry`/`emplac`/`brain`/`patrol`/`aggro`/`hostile`/`npc`.
+`jointturret` (in `OWN`/`PGN`/`STI` skeletons + `own_tur.bgf`) is a **mech** turret-torso joint, not a
+world gun. The destructible world objects (`Landmark`, `CulturalIcon`, `UnscalableTerrain` —
+`CULTURAL.h`) have no weapon/fire/target members of any kind: they take damage and break, nothing more.
+⇒ **Turret/cannon models in the maps (`TT1`/`TT2`/`TWR`/`TK1`/`APC` + their `D` damaged variants) are
+SCENERY.** They never fired in 1995. Making them fire would be inventing a feature, not reconstructing
+one — and it would need an entity class, targeting, and a threat model that the binary has no trace of.

 ## No AI — BT is PvP-only (verified, not a recovery gap)
 The mission system is NETWORKED and BT never had NPCs/AI. Every mech is driven by a `BTPlayer` (or a
 `BTCameraDirector` spectator). The BT registry knows only Mech/Projectile/Missile/BTPlayer/BTTeam; no
