Second Bachelors vs Masters

<p>I currently have a BS in Supply Chain Technology with Six Sigma and Lean Certificates. The degree is made up of the engineering prereqs and a combo of Industrial Eng courses as well as suppl courses. I am also prior military, where I worked as a cryptologist. I have been accepted jnto the Johns Hopkins Masters program for Systems Engineering. I am curious if I should get the masters or go back to school and get a second bachelors in Electrical Engineering (or mechanical?). I value all kinds of feedback. </p>
