The Vietnam War era (1958–1980) saw significant changes to the US Army's structure, doctrine, and heraldic program. The shift to an all-volunteer force, the reorganization of divisions under the ROAD structure, and the introduction of new combat units all generated new DUI authorizations throughout this period. Vietnam-era DUI are scarcer than their WWII counterparts — the Army maintained a larger number of units in the WWII period, and collector interest in that era has driven more pieces onto the market over the decades.
Vietnam-period crests often show different construction characteristics than earlier DUI: changes to approved metals, new manufacturer marks, and evolving fastener systems all provide dating clues for experienced collectors. Some units active in Vietnam carry DUI with direct lineage to WWII and Korean War-era pieces, adding an extra layer of historical depth.
Each piece in this collection is individually examined and noted with production details, maker marks where visible, and any provenance information available. This is a growing category — as WWII items become increasingly rare and expensive, Vietnam-era DUI represent an accessible entry point for new collectors and a specialized focus for advanced ones.
