To become an army special operator is it neccesary to go into one of the Ranger Regiments.?

My ultimate goal is to become a Special Operator of some kind in the Army. I am wanting to enlist in the Army with an 11x option 4 Airborne contract. I don't think that i will be prepared mentally after Infantry OSUT to go through Ranger training. I want to spend a couple of years in an Infantry unit, get my confidence up and then go to some more schools like Air ault and Ranger School. My question is if it is neccasary to get into a Ranger Regiment, or can I apply for Special Forces (aka. Green Berets) after being in lets say the 82nd Airborne or the 101st Air ault.
