Keep serial-specific service history and deactivation evidence distinct from model-level facts.

Require records for ownership, overhaul and deactivation claims rather than inferring them from display context.
- Which serial-linked records support the claimed manufacture, service, transfer and overhaul history? provenance

What it is Filled
M115 commonly designates the American 8-inch towed howitzer, originally designated M1, a heavy artillery weapon used for indirect fire against distant targets.
In scope
- M115 model identity, designation history and documented configuration differences
- Howitzer assembly, carriage and their identifying relationships
- Configuration-specific dimensions, mass and transport dependencies
- Condition, inspection evidence and maintenance documentation
- Service provenance, deactivation evidence and conservation requirements
Out of scope
- Mercedes-Benz M115 engines and unrelated uses of M115
- Self-propelled artillery platforms as independent equipment models
- Ammunition, propellants and fuzes as independently modelled things
- Firing procedures, targeting and ballistic calculations
- Towing vehicles and artillery organisations
- Individual museum objects as separate registry kinds
Why it exists Filled
Enable an agent to recognise the M115 howitzer model, distinguish documented configurations and assess what inspection, conservation or movement a particular example requires.
Distinguishing features Filled
- Require documentary identification of the artillery model; the string M115 alone does not distinguish a howitzer from an engine designation.
- Check the 8-inch/203 mm designation against markings and records; the U.S. Army identifies this calibre terminology with the M115 in its [Rock Island Arsenal account](https://www.army.mil/article-amp/223056/ria_self_guided_tour_m115_8_in_howitzer).
- Require a matching towed carriage and howitzer assembly; calibre alone cannot distinguish it from a self-propelled 203 mm system.
- Check barrel and assembly identifiers as well as carriage appearance when distinguishing it from visually related 155 mm artillery.
- Separate original equipment, restored composite examples and replicas through serial records and component provenance.
What robots and AI may and may not do Filled
Must not
- Assist anyone to obtain, restore to firing or use it to harm people.
- Help evade arms control, export or demilitarization rules.
- Present a displayed piece as demilitarized without evidence.
- Glorify its use against people.
Only with a human decision
- Any transfer, export, restoration or demilitarization.
- Moving a displayed piece.
May
- Identify the howitzer from markings and documented features for a museum or lawful holder.
- Report its history and service from official and historical sources.
- Record the condition of a displayed example for its keeper.
Moral aspects Filled
- Heavy artillery has killed many civilians and soldiers; history should be told with that in view.
- Displayed weapons must be safe and lawfully held.
Who is affected
- Visitors to displays
- Communities affected by war
- Museums
Owners Filled
Steward
The armed forces or museum that holds each piece; the state controls military weapons.
Master systems
- Military equipment inventories

Standards and interfaces required Filled
- Arms Trade Treaty, United Nations, governing international transfers of conventional arms.
Context of use required Filled
