Did i make the right decision ?

Hi, my name is Kevin. I'm 21 yrs old and am airborne infantry in the army. I joined the army about 7 months ago. I went thru osut with no problems. Airborne school same way. When I came home I got to see all my friends and family n now I'm leaving to go to fort Richardson Alaska for 3 years. It sucks because I feel like I will miss so much while I'm gone. My real issue lies within my life goal or dream. I've always wanted to be a police officer. Now originally I wanted to get my bachelor's degree online within these 3 years but now I'm not sure if Il even get the chance to do so. Because of lack of time. I also have other friends that are waiting for there chance to get into the academy. I guess what I really wanna know is am I going to be in any better position than they are when I get out ? Is any of this going to help me ? As far as payscale or getting into the academy or anything at all. Also I want to say that I'm proud of serving my country and wouldn't change that. I'm just wondering if my time In will put me in any better position to pursue my life goals? Any KNOWLEDGEABLE input would really be appreciated. Thank you.
