Enable an AI agent to recognise a T-72, establish its actual configuration and condition, and determine which inspection, preservation, maintenance or movement actions are supported by evidence and authority.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise a T-72, establish its actual configuration and condition, and determine which inspection, preservation, maintenance or movement actions are supported by evidence and authority.
The T-72 is the Uralvagonzavod main-battle-tank family (Object 172M and successors) that entered Soviet service in 1973 as a cheaper, mass-producible counterpart to the T-64, defined by a three-man crew, an AZ floor-carousel autoloader, a 125 mm 2A46-series smoothbore gun, and a compact composite-armoured hull that became the principal late-Cold-War export MBT.
It can be Compare vehicle evidence with candidate T-72 configurations and record a qualified identification.; Reconcile upgrade records with installed equipment and flag mixed or undocumented configurations.; Request targeted inspection of unresolved running-gear, compartment or hazardous-system conditions.; Assess whether documented prerequisites support preservation, maintenance or movement.; Prepare a configuration-specific transport handoff using verified dimensions, mass and restrictions.; Maintain an auditable vehicle history through storage, restoration, rebuild and deactivation..
Distinguishing features
Test a claimed T-72 designation against hull markings, production records and variant documentation; a caption or painted tactical number alone cannot establish identity.
Compare the observed running-gear arrangement, hull geometry, engine deck and exhaust arrangement against documented T-72, T-64 and T-80 references; require agreement across several features.
Compare turret geometry, hatch arrangement and observation-equipment positions with the claimed T-72 configuration and plausible T-90 alternatives; classify obscured or contradictory evidence as unresolved.
Check whether the claimed upgrade designation matches the installed equipment. A separately recognised T-72B3 designation appears in the [US Army vehicle identification guide](https://www.benning.army.mil/infantry/artb/RSLC/content/pdf/20240321%20Vehicle%20Identification%20Study%20Guide_Updated.pdf), but this draft does not establish its identifying equipment.
Distinguish a T-72 tank from a vehicle merely using a related chassis by establishing its documented conversion history and present configuration; retain a boundary question where registry treatment is unknown.
Scope
+ Identification of a vehicle as a T-72 and assessment of competing identifications
+ Distinction between original variant, later upgrade designation and observed configuration
+ Continuity of vehicle identity through rebuilds and component replacements
+ Installed running gear, propulsion, turret, armament, protection and observation equipment
+ Evidence-backed condition, inspection limitations and hazardous-system status
+ Vehicle-specific prerequisites for custody, inspection, maintenance, preservation and movement
- T-64, T-80 and T-90 models and their independent family definitions
- Independent models of ammunition, engines, radios and other replaceable components
- Military formations, crew personnel and organisational readiness
- Tactical employment, targeting and weapon engagement procedures
- Transport vehicles, routes, bridges and workshop infrastructure
- Legal regimes, transfer agreements and maintenance procedures themselves
Characteristics
- Family and variant attribution
- Claimed designation; supported designation; unresolved alternatives; confidence Prevents uncertain recognition from becoming an assumed equipment specification.
- Hull identity and rebuild lineage
- Vehicle linked to observed identifiers, manufacturing evidence and rebuild records Separates persistent vehicle identity from replaced turrets, engines and painted markings.
- Installed configuration
- Dated links to identified hull, turret, propulsion, armament, protection, observation and communication components A variant name does not establish what remains installed after upgrades or repairs.
- Configuration-specific mass
- kg; measured or documented; load state and uncertainty Movement and support decisions require a mass applicable to the actual vehicle.
- Transport envelope
- Length, width and height in mm; turret orientation and external fittings recorded Attachments and configuration affect clearance and transport compatibility.
- Running-gear and propulsion condition
- Separate dated assessments for tracks, suspension, engine, transmission, steering and brakes: unassessed, serviceable, restricted or unserviceable An engine that runs does not establish that the tank can move safely.
- Turret and armament condition
- Installed, removed or unidentified; inspected condition; isolation and deactivation evidence Appearance alone cannot establish functionality or safe access.
- Protection installation condition
- Identified, unidentified, missing, damaged or unassessed by installation; energetic status separately recorded Visible housings do not prove their contents, condition or protective performance.
- Inspection coverage
- Exterior-only, compartment-specific or documented comprehensive inspection; inaccessible areas listed Makes the limits of condition judgments explicit.
- Action authorisation
- Vehicle linked to responsible custodian, authorised action, qualified personnel and applicable documents Physical capability and permission to act are separate requirements.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 28 questions.
T-72 identity and lineage Establish family membership, variant attribution and the identity of the individual hull.
Similar-looking tanks, upgrade labels and replaced assemblies can produce conflicting identities.
Family and variant recognition
Separate a supported identification from a designation supplied by an observer.
Supported T-72 attribution
Record evidence that supports T-72 membership and distinguish it from evidence supporting only a broad tank identification.
- Which markings, records and independently visible hull or turret features support identification as a T-72? definition
- Which T-64, T-80, T-90 or converted-chassis alternatives remain plausible, and what evidence would distinguish them? boundary
Hull continuity
Trace the individual vehicle through rebuilds without confusing component identity with hull identity.
Rebuild and identifier history
Connect identifiers and dated rebuild records while preserving conflicts and gaps.
- Which identifiers belong to the hull, which belong to replaceable assemblies, and which are temporary markings? provenance
- What evidence connects this hull to earlier records after turret replacement, overhaul or renumbering? provenance
T-72 installed configuration Describe the equipment actually present on the vehicle.
An original designation and a later upgrade label may each describe only part of the current configuration.
Hull and turret assemblies
Identify major assemblies and their documented relationship.
Actual assembly combination
Record the observed hull, turret, gun and loading-system identities without inferring compatibility from family membership.
- Which hull, turret, gun and loading-system assemblies are installed, and how was each identified? provenance
- Which records establish that this assembly combination is an approved configuration? boundary
Upgrade and external equipment
Resolve the content of claimed upgrades and subsequent modifications.
Observed upgrade content
Compare documented upgrade content with installed sights, communications, protection modules and external structures.
- Which installed items substantiate the claimed upgrade, and which expected items are absent or unverified? definition
- Which later additions change the vehicle's envelope, access points or inspection requirements? measurement
T-72 mobility and movement Assess the condition and physical constraints relevant to moving the individual tank.
Tracked mobility depends on several systems, while transport requirements depend on the vehicle's actual load and fittings.
Running gear and driveline
Keep propulsion evidence separate from steering, braking and track condition.
Supported mobility state
Record qualified inspection outcomes and restrictions for the installed propulsion and running gear.
- What dated inspections establish the condition of the tracks, suspension, engine, transmission, steering and brakes? measurement
- Which unresolved defects or inspection gaps prevent approval of the proposed movement? action
Movement envelope and load
Establish the dimensions and mass applicable to a proposed movement.
Configuration-specific transport basis
Associate mass and dimensions with turret orientation, external fittings, fluids and carried material.
- What are the verified mass and overall dimensions in the proposed transport configuration, and what remains estimated? measurement
- Which approved vehicle documents and carrier limits must be checked before a qualified operator authorises loading or movement? action
T-72 compartments and hazards Establish compartment condition and the status of systems that constrain access or handling.
A tank may appear intact or deactivated while its interior, armament or protection installations remain unassessed.
Interior access and condition
Record inspection coverage of crew spaces, turret mechanisms and equipment compartments.
Compartment inspection limits
Distinguish observed damage and contamination from inaccessible or unexamined conditions.
- Which crew spaces, turret mechanisms and engine-compartment areas have been inspected, and which remain inaccessible? measurement
- What qualified assessment establishes whether entry or work in each affected compartment is permitted? action
Armament and energetic status
Record evidence about ammunition, armament isolation and potentially energetic protection installations.
Verified hazard status
Keep unknown, declared safe and independently verified conditions distinct without supplying handling procedures.
- What qualified inspection records establish the status of ammunition spaces, the gun, loading mechanisms and any potentially energetic protection modules? provenance
- Which access, maintenance or transport restrictions remain until the relevant hazards are assessed by authorised specialists? action
T-72 service history and disposition Connect configuration and condition evidence to the vehicle's intended custodial use.
A stored tank, restoration project and certified static exhibit require different evidence before work is authorised.
Maintenance and storage history
Identify evidence gaps created by overhaul, component replacement and periods of storage.
Applicable service record
Determine which maintenance and preservation records apply to the current assemblies.
- Which overhaul, replacement and storage records apply to the engine, running gear, turret and protection equipment currently installed? provenance
- Which variant-specific inspections are required before the proposed return to movement, restoration or continued storage? action
Custody and intended use
Relate the tank's present status to a specific proposed action.
Supported disposition decision
Record who may authorise the action and whether vehicle-specific prerequisites have been met.
- Is this T-72 held for storage, maintenance, restoration, display or another documented purpose, and who controls changes to that status? provenance
- What evidence supports the proposed action, including any deactivation certification, inspection conditions and custodian approval? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

Failure modes and hazards
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Penetration of the hull or turret often ignites the AZ carousel under the crew floor, causing ammunition cook-off and turret throw-off.
- Thin roof and engine-deck armour against top-attack ATGMs, artillery submunitions and FPV drones.
- Autoloader jam or damage leaves the three-man crew unable to load the gun by hand at a useful rate.
- Early transmissions give very low reverse speed (about 4-5 km/h), limiting hull-down withdrawal.
- Limited gun depression makes hull-down fire from reverse slopes harder than in many Western MBTs.
- External fuel tanks and fender tanks add fire load after mobility or flank hits.
- Tracks, road wheels and the relatively light hull are vulnerable to mines, artillery and mobility kills.
- Silhouette overlap with T-64/T-80/T-90 produces identification errors and fratricide risk.

Regional variation
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Soviet/Russian line: T-72A then T-72B/B3 with domestic APFSDS, ERA and radios; export T-72M/M1/S were often sold with simpler armour, sights and ammunition.
- India: T-72M1 Ajeya and Combat Improved Ajeya, integrated with national ammunition, communications and later thermal sights.
- Poland: T-72M1 stocks and the PT-91 Twardy (Drawa FCS, Polish ERA layout) treated as a national type.
- Czechoslovakia/Czechia/Slovakia: T-72M and the deep T-72M4 CZ rebuild.
- Yugoslavia/Serbia: M-84 family derived from T-72M, usually catalogued as a separate tank.
- Iraq: locally assembled T-72M as Asad Babil (Lion of Babylon), with mixed build quality.
- Ukraine: T-72AMT and other national overhauls of T-72A/B hulls, distinct from Russian B3 in sights, ERA and radios.
- Which of these regional variation hold for the sense of T-72 this model covers, and on what evidence? provenance
Neighbouring kinds and how to tell them apart
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- T-64 - T-72 has six large rubber-tyred road wheels and a left-rear V-12 diesel exhaust; T-64 has smaller, tighter-spaced wheels, a 5TDF opposed-piston engine and a horizontal cassette autoloader rather than the AZ carousel.
- T-80 - T-80B/U use a gas-turbine engine with a different rear deck and no T-72-style left exhaust grille; later diesel T-80UD/T-80BVM still differ in suspension, engine deck and typically in turret/ERA fit.
- T-90 (especially Object 188) - Early T-90 is a T-72B derivative: look for Shtora-1 IR-dazzler 'eyes' and a different FCS; T-90A/M have a welded turret and are not T-72B3 even when ERA layouts look similar.
- T-62 - Four-man tank with a 115 mm gun, no autoloader, a mid-barrel fume extractor and a different turret; lighter and older than any T-72.
- M-84 - Yugoslav production from the T-72M: different engine deck, DNNS-2 sighting and national equipment; treated as its own type by operators and catalogues.
- PT-91 Twardy - Polish rebuild of the T-72M1 with Drawa fire-control, a distinctive ERA array and different side skirts; not a Russian T-72B3.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of T-72 this model covers, and on what evidence? provenance

What the second pass must settle
- Does vr.tr.t-72 denote the entire T-72 family or a narrower baseline type, and how should licensed derivatives and chassis conversions be related without creating unauthorised registry splits?
- Does an existing Vercy world model already own this concept and therefore require this registry entry to link to it?
- Which authoritative references establish reliable distinctions among T-72 variants and neighbouring tank families, including heavily modified or partially obscured vehicles?
- Which manufacturer or operator documents establish configuration compatibility, physical measurements and applicable inspection requirements for each supported variant?
- What jurisdiction-specific evidence establishes deactivation and permitted custodial actions for an individual vehicle, and how long do those assessments remain applicable?
