How can I go from West Point to being an officer in the 75th Rangers?

I am a cadet in the Civil Air Patrol Cadet program. My goal is to go to West Point and be an officer in the Rangers. How can this be done?
Update: You can go to Ranger school during the summer while you're at West Point?
Update 2: Shock and Awe, great answer I'd vote it the best but I'm new so I cant. Thanks for your service.
