The United States Army Rangers are an Airborne unit, they are not directly Special Operations, but just Special Forces.
They are attributed to the training of local/indigenous law enforcement and military as well as anything from direct combat to hostage rescue.
They are basically the best of Army Infantrymen, who are Airborne and specially trained.
They do have a small branch within called Delta Force, they are part of the Airborne Rangers though most the time see themselves as separates. They are the Special Operations, the Navy SEALs, Phoenix Raven, Force Recon, SAS, Spetsnaz equivalent if you must.
