What are the best branches for Army Officers and why?

I can't believe the question

Pick a branch that you can use once you get out. The military likes to act like people will be lining up to hire you after being an Officer. This isn't the case, I had to go back to graduate school to find a job that paid nearly what I was making as an Army Officer. Also, think about long term mileage on your body. I wanted to go Infantry, was extremely fit. After a while all of the abuse to my body caught up to me. Now, I wish I joined the Air Force lol. When you're and Officer, as you know, you're expected to go 100% all out during PT every single day, at least if you're at a line unit. After a while, the body does break down. Spine issues blow!

Looking to retire, go Engineer.

What are you getting your degree in?

MI is a rewarding branch, but it's a high learning curve, unless you have aviation and land based threat understanding. After your career, you can work as a civilian in a similar field or cyber security, FBI, etc.

Combat Arms is the most fun, but Intel and Cyber have better potential to land one a good job after the Army. I was dual-branched in FA and MI back when the Army used to allow this in the 1980s. Being in the FA helped me hone my leadership, planning and operations skills. However, it was primarily my Intel experience that landed me my first job post-retirement. The position was as a program (and later division) manager leading R&D efforts on two DARPA projects employing intelligence TTPs to develop predictive computer network defense technology. Being in the FA alone would never have equipped me for that position.

I was dual branched in Field Artillery and Intelligence back when the Army used to do that. Combat Arms is where the fun is. I had a blast in the Field Artiller! However, MI and Cyber create better job potential after the Army. My Intel experience is what landed me my first job after I retired.

It depends on what your desired end state is. Do you want to become a Commanding General? Do you want to become more marketable in the civilian marketplace? Each end state demands different criteria and each branch offers solutions for those criteria.

I've been Signal, Ordnance, quartermaster , and Logistics. All previous comemts are correct, but think carefully about what you are goimg to do. I started Signal and it was fun, but ultimately not for me. I recommend shadowing your top 3 and then make your wish list. The Army will pick in the end most times.

You will be most successful in a field that suits your personal skill set and personality. It may be true that some branches have a better opportunity for promotion but over a 20 - 30 year career this will change drastically based on national policy and national defense needs. However. a good solid career where you do well by doing good should be your personal objective not just rank. The military recognizes and rewards excellence.
