WW2 US Army Chemical Corps Garrison Cap

The WW2 US Army Chemical Corps Garrison Cap is a piece of standard issue headgear worn by personnel in the Chemical Corps branch of the United States Army during the Second World War. This cap, also known as a side cap or overseas cap, features a foldable design made from wool fabric and is characterized by its branch-specific piping—typically featuring the distinctive golden yellow color representing the Chemical Corps. The interior generally includes a cotton lining and may bear original manufacturer stamps or size markings. The garrison cap served as part of both dress and everyday uniforms, providing a practical and regulation-compliant alternative to the service cap. Its design allowed for easy storage and compatibility with other uniform elements. The Chemical Corps was tasked with defense against chemical, biological, radiological, and smoke operations, making this cap a representative artifact of their specialized role in the US Army during World War II.
