MBA or Masters in Criminal Justice?

I am currently in a Army officer program and I am about to receive my bachelors in business management this spring. I have one year until I become a intelligence officer in the Army National Guard. During this time I will be starting my masters’ degree this summer. I hope to work for a federal agency such as the FBI, DEA, etc. My only worry is if these do not pan out for any reason, what good is a master in criminal going to do. Further more which degree would be better for the agencies? Please advise I asked so many people and so many have various opinions. I need to decide very soon though, thank you!
