For one, lets start with Navy SEALs, most known because they have the most media coverage, kind of reminds me of the boys at Iwo Jima who raised the flag, knowing that many more raised the flag, but they were killed, these men spent the rest of their lives depressed, some of them killing themselves. They used them as the picture boys, a way to make a few bucks. It baffles my mind that people actually believe the SEALs ran this operation by themselves. Anyways, SEALs, your new hollywood sea mammals, are extremely elite killers. They train in hostage rescue, raiding compounds, urban warfare, unconventional warfare. Stuff like that. Its really pretty simple. But yet so complicated.
Delta, they do the same things, EXCEPT, as far as I know, (There's a guy roaming Yahoo! who I know has had the honor to know CAG shooters, and it'd be great for him to answer on this one), but I believe Delta deals with major hostage situations, and hard core deep reconnaissance, they blend in with the enemy, become their friends. Its a very different job, and due to their job they are considered the most "secretive". Doesn't mean they are more elite, that's just how they run things. Not everyone wants their picture on the front of 17 Magazine.
Army 75th Rangers, they are the only Ranger component of Special Operations, they specialize in close-combat, they are hard chargers. They tandem line into a combat zone out of Hawks usually being flown by SOAR, and then conduct compound raids, secure air fields, and so on. This is usually done with the help of Army: Special Forces, they do pretty much the same thing, they may be more on the intelligence side of raiding air fields and what not though.
MARSOC/MCOT Marines, they focus on Reconnaissance.
Air Force Pararescue Jumpers and Combat Controllers. Pararescue Jumpers and Combat Controllers receive the longest training in the Armed Forces, and yes it is the "toughest". Not that that matters, what matters is that you're passionate about your job, allowing you to do it to the fullest extent. If you're doing it for the wrong reasons, such as image, you're going to get someone killed. I know, it sounds counter-intuitive that the Air Force has the hardest/most dangerous job in the Armed Forces, but its true.
What you REALLY need to realize before I go further into this, is that without each other, all of these Special Operations Forces, would be worthless. They are all a part of USSOCOM/JSOC. They all perform EXTREMELY important jobs, and without each other, the jobs of each other would be impossible.
You have Combat Control going in first, their motto is quite literally "First There", they set up air traffic control, set up extraction zones, set up the zones where their USSOCOM counter parts will be dropped in, SEALs, Delta, whoever it may be, and they also perform deep reconnaissance. Now, once they've done all that, performed their recon, they direct in their USSOCOM buddies, for example the SEALs, the SEALs come in out of a SOAR flown Black Hawk, drop down, Combat Controller (CCT) then attaches to the SEAL team, and provides direct rifle fire, and also provides close-air support. (So on top of being trained for Deep Recon, Air Traffic Control, and Close-Air Support, CCT's are trained to h**p it with each of the Special Operations Forces, they all have different styles).
Together, they will control the world. Then Delta comes into play when there's hostages (You need to understand right now, 99?f the time CCT will be there, they have the job that requires them to be in most of the missions), ad what not, raids compounds, a lot about them is pretty secret, but I've heard they are somewhat similar to SEALs, they just work in different zones than SEALs, I've heard that Delta works in Iraq when SEALs work in Afghanistan, which is why SEALs were given the job to take out Osama, they are closer to Pakistan. That's what I've ready anyways.
And then the 75th Rangers and Army SF come in to be the "groundpounders" of special operations, when Special Operations needs a full frontal assault, those two do the job better than most warriors on this planet could. Their assaults allow CCT to drop in behind enemy lines with SEALs, and so on.
MARSOC Marines, they do reconnaissance, and 99?f it will always be reconnaissance, they are also known to provide long-distance direct action fire in support of Special Operations warfare.
And PJ's, Air Force Pararescue Jumpers, what they do is go in when someone important needs their ass saved, when a SEAL goes down behind enemy lines and is wounded badly, PJ's go in to get his ass out, they go in for important assets, maybe a downed CCT, Delta operator, CIA operator, they perform combat search and rescue, and they also assist in securing captured embassies.
USSOCOM performs together for a reason. Really. There is no rambo.
