On the news, they are commonly referred to as "U.S. Army special forces", which is what they are.
Green Berets are highly skilled operators, trainers, and teachers. Area-oriented, these soldiers are specially trained in their area's native language and culture. They train to perform five doctrinal missions: Foreign Internal Defense (FID), Unconventional Warfare (UW), Special Reconnaissance (SR),
Direct Action (DA) and Combating Terrorism (CBT). They infiltrate and
exfiltrate specified operational areas by sea, air, and land.
