Do you need a degree to be a cop ?

I am in the army right now.( airborne infantry) I want to pursue a career in law enforcement. I'm getting my bachelor's in criminal justice online. My biggest questions are do I really need that degree. I mean I don't have much free time n if I wouldn't need a degree I will have more time for myself.. since that time is very limited in the first place haha. I mean don't get me wrong if this degree will pay off than I have no problem dedicating myself n getting it done. Also what are other things that I could do that would give me a better chance of getting right into the academy, and set me up for a successful career. I would really appreciate some help Haha thank you.
