ORDNANCE

Ordnance covers ammunition, components, and related items larger than standard small arms calibers, generally exceeding 12.7 mm, and associated with military, naval, and heavy weapons systems. This category includes a wide range of material such as mortar boosters and charges, large caliber blanks, practice and drill cartridges, dummy rounds, impulse cartridges, grenade and mine related components, and ancillary hardware used in artillery, automatic weapons, and special purpose launchers. The material reflects both combat and training roles, as well as logistical and support functions required to operate larger weapons systems.

Items in this category span multiple nations, time periods, and technical standards, and include live, inert, dummy, fired, sectioned, and replica examples, along with packaging and associated accessories. Variations in case construction, materials, color coding, fuzes, payload bodies, and markings document differences between service branches, manufacturers, and intended uses. From a collector and research perspective, ordnance material is significant for understanding how large caliber ammunition systems were designed, issued, and supported, providing essential context for the study of heavy weapons development, military supply chains, and the evolution of artillery and explosive ordnance technology.
