As was stated, yes, you can eventually make it into SF if you have the drive to get there. That is the direction my son is working towards he is currently a Yuk. A close friend of mine has a son who is well down the path as a USMA grad. He started as an Infantry officer in the 82nd, then went to the 75 Ranger Reg, completed Green Beret selection, and is currently in the Q Course. You do need to make sure you want to be part of the military regardless of whether you are in SF or not as there are no guarantees.
