List of the United States Army weapons by supply catalog designation
This is a historic (index) list of United States Army weapons and materiel, by their Standard Nomenclature List (SNL) group and individual designations — an alpha-numeric nomenclature system used in the United States Army Ordnance Corps Supply Catalogues used from about 1930 to about 1958. The July 1943 Ordnance Publications For Supply Index – OPSI – (page2) explains that the "Index of Standard Nomenclature Lists (...) covers – by groups, and subdivisions of groups – all classes of equipment and supplies, assigned to the Ordnance Department for procurement, storage, issue, and maintenance." The designations in this Wikipedia list represent so-called "major items".
