Your best bet is to start talking to local recruiter who may have the same MOS you are in search of. Making the commitment to join take patience and understanding. It sounds like you have not even started your search so I also suggest you talk with local VFW members who can give you some feedback. Explore your own interests and not someone else's agenda! If you make it through all the processing and testing, best bet is to get a job/MOS in the military that can use an Army Ranger. Not all MOSs are open to Ranger School!
Best of luck to you!
Local recruiter will have all the information you need to accomplish this training.
An Army Recruiter would be happy to discuss this with you.
