A design for a Shoulder Sleeve Insignia (SSI) was submitted by Captain John W. Frye of the 77th SFG and was approved by the US Army on 22 August 1955.
The arrowhead alludes to the American Indian’s basic skills in which Special Forces personnel are trained to a high degree. The dagger represents the unconventional nature of Special Forces operations, and the three lightning flashes, their ability to strike rapidly by air, water, or land.
The iconic SF Insignia was born.
