This is a very interesting photograph of special operations gear from the Vietnam War era.
A lightweight rain poncho for special forces, believed to have been procured by the CISO (Counterinsurgency Support Office) under a 1967 contract.
At first glance, its simple olive drab (OD) color and shape resemble standard U.S. military rain ponchos of the era, but its most distinctive feature is the extremely thin and lightweight fabric—a departure from standard U.S. military-issued ponchos. Its design is highly practical, clearly prioritizing portability for special forces operating in tropical environments.
Based in Okinawa, the CISO was known during the Vietnam War for procuring equipment that was difficult to obtain through standard U.S. military supply channels and supplying it to special operations units and other forces.Such equipment is closely tied to the context of special operations and irregular warfare—including MACV-SOG and CIDG—and possesses a unique appeal distinct from standard government-issued items.
A particularly noteworthy feature of this item is the stamp left on the fabric.
A marking indicating the year 1967 can be confirmed, and there is also a DAJ-series contract number, which differs from standard U.S. mainland contracts. This is a crucial detail indicating that the item was procured under an overseas contract in the Far East.
Although there are no markings that directly identify the country of manufacture, considering the procurement context of CISO and the nature of the DAJ contract, it is highly likely that this particular item was manufactured in the Far East, including Japan. It is safe to assume it was made in mainland Japan or Okinawa. The fact that its origins differ from those of typical U.S.-made government-issued ponchos is what makes this piece so interesting.
The large hood is equipped with a drawcord. The body is cut generously, and the structure—with a row of snap buttons along the sides—is quintessentially poncho-like. While retaining the practicality characteristic of military gear—designed to be quickly pulled over one’s equipment—it is crafted from a lightweight nylon-based fabric, making it exceptionally light and airy.
Above all, what makes this piece truly remarkable is its condition—it appears to be an unused item from that era. Although it is special operations gear that has endured for over half a century, the olive drab (OD) color remains vivid, and the rare stamp is clearly visible. While there is some slight signs of fabric deterioration due to long-term storage, overall, it remains in exceptionally good condition.
CISO-related items are not a category where large quantities remain, as is often the case with standard U.S. military issue gear. Moreover, the combination of a 1967 contract—during the height of the Vietnam War—a DAJ contract, a lightweight specification, and the fact that it is an unused item with stamps still intact makes this piece exceptionally appealing.
This is a special piece that combines historical significance with a striking presence—a must-see for anyone delving into special operations gear from the Vietnam War era, such as MACV-SOG, CIDG, and CISO.
*Due to the lightweight, vintage nature of the material, we recommend this item for collection rather than practical use.
