6.2 Details on record keeping and/or authority for destruction.
Weapons to be destroyed are transported by authorised personnel to the civilian facility that carries out the destruction. A list of all weapons (with serial numbers) in the shipment is drawn up for each shipment. Authorised personnel monitor the destruction process and check the data on the weapons destroyed against the lists issued by the sending authority. The weapons are then labelled "Destroyed" in the central register of weapons.
All weapons remain in the data base(s) until every weapon of a specific type has been destroyed, lost or otherwise disposed of. As far as we know, there are no provisions which require storage of data beyond this. Since World War II, however, this has not been a problem, as the military has retained a few specimens of all relevant weapons types.
Decisions to destroy individual weapons are taken by FLO/LAND and the Police Procurement Service (PPS). Weapons designated for destruction usually display such a degree of wear or damage that it is no longer cost-effective to repair them. Decisions to decommission weapons types are taken by the Headquarters Defence Command.
