Original US Army 18th Engineer Brigade Patch | Subdued Twill | Vietnam Era
Description
The sword and castle wall—building the road to victory in the jungle.
-
Unit History: Deploying to Vietnam in 1965, the 18th Engineer Brigade was responsible for massive construction efforts, including airfields, base camps, roads, and bridges throughout the country. As combat engineers, they often had to fight to defend the very infrastructure they were building.
-
Design: The diamond-shaped insignia depicts a sword pointing upward, piercing through a section of a crenellated castle wall. The wall represents construction and the Engineer Corps, while the sword symbolizes their combat role.
-
Early Manufacturing (Twill & Cut Edge): To speed up production when the Army transitioned to subdued insignia, only the black design was stitched onto an OD green twill fabric base. The reverse shows the exposed fabric and period-correct white bobbin thread. The raw cut edge is a true hallmark of 1960s production.
-
Condition: Mint New Old Stock (NOS). Unissued, unsewn, and perfectly preserved with clean edges.
-
