Army Green Berets — "Special Forces"
Notably, Green Berets have some of the toughest initial training in the entire military (at the risk of drawing the ire of SEALs and Marine Recon). Their initial test lasts an incredible 24 days, and that's just to see if you can attend the Green Beret qualification course.
If they are compromised during a mission, the US government may deny all knowledge. SOG is considered the most secretive special operations force within the United States, with fewer than 100 operators. The group generally recruits personnel from special mission units within the U.S. Special Operations community.
Special Operations are the most elite forces in the U.S. Army. Soldiers in this unit typically work in small, tactical teams on the most varied and sensitive missions the Army undertakes.
Formed in 1965, the Para (Special Forces) are the largest and most important part of the Special Forces of India. They are highly trained units of the Indian Army, meant to operate behind enemy lines. Ghatak Commandos are tactical level commando units attached to each battalion of the army.
United States Navy SEALs are perhaps the finest special operations forces in the world. The competitive standard to even be considered for BUD/S training is to swim 500 yards in 10:30, 79 push-ups, 79 sit-ups, 11 pull-ups, and a 10:20 1.5 mile run. That's just to get in.
British Special Air Service (SAS)
They are the number one fighting force in the world and are trained to perform equally well in all other fields. Their insignia bears the famous phrase 'Who dares wins.
SEAL Team 6, officially known as United States Naval Special Warfare Development Group (DEVGRU), and Delta Force, officially known as 1st Special Forces Operational Detachment-Delta (1st SFOD-D), are the most highly trained elite forces in the US military.
The Marine Raider Regiment (MRR), formerly known as the Marine Special Operations Regiment (MSOR). The Marine Raiders is a special operations force of the United States Marine Corps, which is a part of Marine Corps Special Operations Command (MARSOC).
Army Special Forces is a much larger organization than Delta Force, which is a small subset of Army Special Operations Command.
The Group for Specialized Tactics, also known as the Ghosts, is an elite Special Mission Unit within the US Army and JSOC and is located at Fort Bragg, North Carolina. The unit was established in 1994 and is a secretive special operations force.
For decades, U.S. military leaders have prohibited service members from growing beards, arguing that facial hair not only disrupts a clean, professional appearance, but also interferes with the seal of a gas mask, oxygen mask or other devices that service members wear to survive hazardous environments.
Although the Marines are highly respected and considered one of the most elite fighting forces, the Navy SEALs training is far more rigorous and demanding than that of the Marines.
Each branch of the United States Armed Forces has unique characteristics. Every branch has specialized units, different uniforms and different traditions. But what specifically separates the Marines from the other branches? Although they are one of the smaller military branches, they are elite and mighty like the rest.
You can apply to become a Navy SEAL as a civilian, a Navy sailor or even as a service member from another military branch. Both new recruits and active-duty military candidates must pass a battery of physical, technical and psychological exams.

No, Delta Force is an Army unit. The Marines have the Raiders, which are special operations units that are part of MARSOC. They are more comparable to Army Special Forces (aka the Green Berets). The Marines do not have a unit with capabilities similar to Delta.
The U.S. Army Special Forces, also known as the Green Berets, are known for unconventional warfare, special reconnaissance, and counterterrorism skills. Delta Force is the Army's elite counterterrorism unit. It is highly skilled in sniping and close-quarters combat ability.
In the end, there's no real definitive answer to who is tougher between Navy SEALs and Delta Force - they're both badasses in my opinion - and if you favor either one over the other in terms of being tougher, that's pretty much like taking sides in an evenly matched Army vs. Navy football game.
The toughest SAS fitness test in the world is the Russian Alpha Group Spetsnaz. To gain selection to the Russia's special forces unit, applicants must undergo a gruelling seven part fitness challenge that finishes with a literal fight.
