How hard is R.I.P. to become a U.S. army ranger?

So future USMC you some how don't know how hard RIP is but you do know that Marine training is harder then both although you have never even been to Marine Corps Boot Camp. Please STFU you make yourself look so stupid coming on here chanting your Marine Corps pride. By the way why are you even saying Semper Fi? Marines don't take to kindly to people using a saying that they haven't earned the right to say. Pull your head out of your as* and realize Rangers are one of the few elite forces this country has and the Corps as a whole isn't one of them.
