Green Berets 

(UK) Member of the British Royal Marine Commandos.
(USA) Member of the US Army Special Forces.

"Green Beret" is the nicknames, because of their headgear. Which is a green beret, though this is moreso on the US Special Forces, than the Royal Marines.

Don't mess with either of those fucking elites though. The green berets = 10 seconds from pwnage (if you're a terrorist)

Yank: I was in the green berets, dude.
Brit: I was a green beret, mate.

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.

Green Berets, with the help of local militas, are chasing down drug lords in Columbia.

Green Beret 

Really Bad Ass Soldiers that specialize in Airborne, covert operations. They Can be Engineers, Doctors, Communicatize and of course Infantryman! Don't mess with any of them! They can kill you with a sticky Note. They can take on entire Armies with just one Squad consisting of 12 guys. When they Get Angry they ram their heads into on coming traffic to calm down.

Fighting soldiers from the sky
Fearless men who jump and die
Men who mean just what they say
The brave men of the Green Beret

Silver wings upon their chest
These are men, America's best
One hundred men will test today
But only three win the Green Beret

Trained to live off nature's land
Trained in combat, hand-to-hand
Men who fight by night and day
Courage peak from the Green Berets
