Which is a better major for me, Business Admin or Organizational Leadership (both with a logisitcs/supply chain emphasis/concentration)?

I think you may need to look at your statement and read it a few times to get the answer. You are taking classes to learn X because you want a job in Y. Why not first figure out what you want to do when you get out first. Get up on LinkedIn, Indeed, Monster, ect and start targeting jobs and companies that excite you. Look at the education requirement for these jobs and the education level and experience of your connections on LI. Right now, where you are, you have the finest global logistical organization in the world. Go and study it. // Pro Tip: Logistics is always changing so everything you learn has an exportation date till the next new shinny technology comes along. Visit with your aviation brothers and hang out with the UAV team. Distribution via UAVs is the next thing in transportation. Artificial Intelligence, the Army is testing driverless vehicles now. There are two emerging logistical items that you could be doing now in the Army. Best of Luck

My thoughts having spent many years in the corporate world. Hard skills matter more than all others. People who understand math & science are predominant in leadership roles and high paying and high influence individual contributor roles. Whether it's finance, systems engineering, logistics, or whatever, it's important to to take calculus and and other classes, such as statistical analysis for which calculus is a prerequisite.

So, I recommend the BS degree versus the BA. If the hard skill classes are making it tough, then slow down, take fewer credits and more time. For the other classes, take the ones that work the communications skills. Do a lot of writing. Learn how to formally research a topic.

You can always do the other classes that are hanging you up at a later date.
