Original Vietnam-era subdued patch for the Puerto Rico National Guard, designed to complement the olive drab field uniform standard of the period. The muted green-on-green colorway exemplifies the practical insignia philosophy of the 1960s–70s, prioritizing low visibility over ceremonial display.

Manufactured to exacting military specifications, this patch carries the historical authenticity collectors seek. The subdued finish and precise embroidery reflect the durability requirements of active service wear, making it a genuine artifact of Cold War-era National Guard operations.

Ideal for uniform restoration, military history collections, and those documenting the evolution of Puerto Rico National Guard insignia.
