Go Marine Corps infantry, or Army infantry. From there you can try out for Special Forces.

If you fail BUD/S (SEAL training) then you'll likely be stuck on a surface ship. Also, their attrition rate is crazy, so most people don't make it unless they're insane endurance athletes. If you can't swim well, you don't stand a chance, and if you can't run marathons, forget doing this.

Pararescue Jumpers (PJ's) are special ops, and its competitive, much like the SEALs, so there's no guarantee you can get a slot there either. You'd likely be stuck on an Air Force base in the middle of nowhere (Cheyenne, Wyoming and Minot, North Dakota are some of your better options), in a command climate that hardly feels military and isn't terribly hard-core like you seem to want either.

Every Marine is a Rifleman, so at the least, any job you have in the Marines will come with that Infantry background regardless of what it is. I'm guessing you'd want to be Marine Infantry, which is entirely do-able, if you pass boot camp (which itself is the only basic training that's considered a good enough precursor to Special Operations).

You can also apply for MARSOC (Marine Special Operations), formerly known as Force Recon, if you want to be on the same level as Green Berets, SEALs, and Air Force PJ's. You need to be smart ,a total stud at PT, and pass all schools they send you to, which will likely be a lot worse than the hell you found yourself in at boot camp.

There's no easy road here, but who wants that anyway.

I would say Marines, but you should ask people like your parents. Navy Seals and Pararescumen are both special branches so you would have to do a few years in Navy for the seals or serve in the Air force to join the Pararescumen. Marine you could enlist or go to college and become an officer; same with every other branch. The special ops in Marines are MARSOC if you want to do that kind of thing.

If you join the Army on a 11x contract you can try out for one of the 3 SOFs we have. Rangers, Special Forces, and Delta Force. You have more options.

Yet another one that wants to try an compare an entire branch of service with special warfare/special operations units. It doesn't work.

Do your research. Here's a link with info on Marine Boot Camp and Life in the Marine Corps.

Rofl 2 Spec. Ops and one normal branch.

Listen before you jump into combat and strap into a kevlar vest please think about your future after the military. The military should be used as a tool to help you after your service and combat situations are extremely mentally and physically draining. It's not for fun it's for your future.
