Special warfare shirt belonged to Lt. Col. Juan W. Spann, 2 tours in Vietnam with 101st Airborne Divison. And participated in Operation Somerset Plain (August 1968).

About special warfare shirt:
In the early 1960s, Natick Laboratories began developing prototype jungle clothing uniforms for the Special Forces in Southeast Asia. One such example is the two-piece “Special Warfare” uniform. Made from 6oz nylon/cotton poplin, it was used until 1965. You can identify these uniforms by the extra gas-flap and adjustable sleeve gusset on the arms.
If the tag’s text is still readable, it will say “SPECIAL.WARFARE”. My example has the contract number “CONT.NO.5186”. According to forum discussions, the term “Special Warfare” refers to conditions outside the normal temperature/climate expected for the US Army.


This uniform was not a private purchase like FOTL (Fruit of the Loom) nor privately tailored like Maharajah; it was indeed issued to personnel before introducing the 1st pattern jungle jacket. The material is very thin, making these items rare, especially the trousers (information sourced from Shelby Stanton’s book and the USMF forum).
