Special Forces crest with the De Oppresso Liber motto, printed on the left chest.
The Special Forces crest brings together crossed arrows and a fighting knife drawn from the heritage of the First Special Service Force. The crossed arrows were worn as the Force's branch insignia during World War II, while the dagger recalls its distinctive V-42 fighting knife. The Army approved the Special Forces distinctive unit insignia on July 8, 1960, joining those symbols above the motto De Oppresso Liber.
The motto expresses the mission of liberation from oppression. The crest became a shared symbol of the Special Forces Regiment, connecting the Green Berets to the combined American-Canadian force that preceded them. It represents that broader Special Forces identity rather than a particular group or battalion.
