U.S. Army Special Forces Branch Established as a Basic Branch of the Army
Today we recognize the establishment of the U.S. Army Special Forces Branch, which is a defining moment in the evolution of America’s special operations forces.
While Special Forces traces its roots to World War II formations like the OSS Operational Groups and the 1st Special Service Force, the branch was formally established on April 9, 1987. This milestone institutionalized a capability that had already proven essential in irregular warfare, partnership, and global competition.
From its activation in 1952 with the 10th Special Forces Group to its expansion during Vietnam and beyond, Special Forces has remained at the forefront of missions that demand precision, adaptability, and trust — from unconventional warfare and foreign internal defense to counterterrorism and special reconnaissance.
The green beret, authorized by President John F. Kennedy, and the motto “De Oppresso Liber” (To Free the Oppressed) reflect more than tradition. They represent a mindset.
At JSOU, we study and teach a mindset grounded in cultural understanding, disciplined initiative, and the ability to operate in ambiguity. It is central to Advancing the SOF Warrior Mind and preparing leaders for today’s complex operating environment.
On this anniversary, we recognize the legacy of Special Forces and the enduring role they play in defending the nation, often quietly, always decisively.
