What advice would you give to enlisted soldiers interested in entering the officer ranks?

Full agree with Author. I seen a few NCO's that were
"Top notch" but Hated the Officer corp side. It seed to some there experience worked against them. Cause of the old adage Nobody trust a 2nd LT.

You've already received very sage advise. What many junior officers don't realize is the responsibility a "commission" has. We serve at the pleasure of the President (don't go there) and can command. In the Navy, a Line Officer eligible for command at sea (basically all Academy, NROTC and OCS) are senior to any staff (med. JAG. ETC) when aboard a craft or ship and responsible for its safe conduct. A solo O-1 Line officer on a small craft with an O-7 Medical Officer has all the responsibility and authority over the boat while aboard. Just an example.

My dad, a WWII B-17 gunner, Stalag 17POW, Korea B-29 gunner supported my application for military scholarships, and I went the NROTC route.

He passed on two pieces of advice which stood me in good stead for 25 yes and into civilian life.
1. Always take care of your men (people) no matter the issue. Never allow another to criticize your subordinates--you are responsible.

2. Never let your boss get surprised, especially if you or one of your people mess up. (A corollary is once given an order, do not, DO NOT, lay it off on a senior in presence of your personnel. Once the order is given, salute the flag and get on with it. )

From experiences, I would say become the leadership you would like to see in your current position, embody that and train, teach, educate, and prepare your soldiers. The goal is simple but yet hard to accomplish is the ability to think on your feet know the right from wrong and known when to apply the means you have trained to the reality of your job, position, and leadership. You have an advantage. You are enlisted first and trying to make the transition, so you should be able to not only take that with you to the other side but be understanding, and that will also help you in becoming a better leader. Also, the money increase is always good, but what is it worth if you don't know how to have the sense with your money and expenses. Financial instability can affect your morals, emotions, financial position, and ultimately your life.

God speed, head on a swivel, and stay solid!

Honestly. Same thing I tell most people no matter where they are going with their career or without. Essentially you have seen many degrees of leadership and leadership mentalities. Be a sponge and absorb negative and great characteristics. Learn from the negative leaders you have had and do the opposite. On the flip side emulate the great characteristics you have received. And if you make a mistake own it and move on. The Army in general is just a learning curve.

Get all you can get. Don’t care what anyone else thinks. Going from enlisted to officer shows you have drive and in time everything evens out. Don’t ever worry what other people say. This can only help you when you retire and will be an excellent return on your hard work.

Never Forget where you started from to become the Officer that you shall be in the Future.
Most of the Officers that I experienced with the Fleet from Lt on down followed the spirit of Haughtiness, by looking down on people below their rank. At COMDESRON II, the Officers was your average Joe and didn't look down on others.

Try searching this and similar questions. There are quite a few on here for more opinions.

I would give 2 pieces of advice that are really specific to you, given your MOS and the fact that FC is a really small community.

One, keep in mind that if you go from SPC to a 2LT in the same unit, there will be some difficulty initially in transitioning to a position of authority not only over people that are currently your peers, but also those who are currently your first line leaders (Squad Leaders, Section Sergeants, Det SGT/1SG depending on if you are in FMSD/FMSU/FMSC). This will take a period of adjustment not just for you, but for them as well. Maintain your authority and professionalism with them, and this will eventually pass. Just make sure to listen to your NCOs and peers (while still making your own decisions!), and be willing to ask questions.

Now for the 2nd bit. As a (now former) FMSU Commander, I am curious—do you wish to continue in the FC Branch? If so, like I said previously FC is a very small community; even more so for the officers. With the current force structure, unless if you are able to get into a FMSC, positions beyond the rank of MAJ are scarce. My advice is to remain open to the possibility of doing a CCC in a branch that has more numerous ways for you to serve later in your career, assuming that that is what you want.

One of my FMSD Commanders just finished Logistics CCC right before I cycled out of command, for instance. Instead of doing a full branch transfer and dropping FC, he was able to keep FC as a secondary AOC. This allows him to do FC or LG jobs, and broadens his operational knowledge as well.

The biggest piece of advice I have is to examine your motives. I mean, take a really deep dive into your own navel and ask yourself why you want it. The extra pay isn't worth it. The benefits of being saluted and called sir are short shrift. You need to come to grips with the knowledge that, as much as the enlisted ranks think you have it cushy, the truth is that it's your job as an officer to make sure they get fed, they get mail, they get sleep, they pass the SQT, CTT, APFT, ARTEP, and anything else going while you take the heat for every failure, no-go, and no-show. This all too often results in you not getting fed, having to wait days for your mail, you missing sleep, and you working harder than any four men in your unit just to stay even with your peers -- double that if you want to shine. With the rank comes the responsibility. Are you sure you're up to it? If you ARE sure, you're fooling yourself (because no 2LT EVER is).
Here's the truth of the matter -- as an officer it's not enough to just be a good soldier. You have to be able to think, plan, motivate, obey and command all at the same time. You have to be able to take inadequate orders and turn them into a successful mission in the full knowledge that it is at least as likely as not that you will receive zero recognition for a job well done. And you have to have skin so thick that you take the knocks and keep coming back for more. You can NEVER quit, you cannot allow yourself to accept personal failure because if you do, so will your soldiers. You must know instinctively that, even as a butter-barred shavetail, your actions will set the standard for the men you "lead," all the while knowing that it is actually your NCO's leading YOU until you find your feet -- and probably after that as well. But find your feet you must because there is nothing that can destroy a unit's ability to fight effectively more quickly that to be stuck with an officer they do not trust and respect.
If you want to be an officer in spite of the fact that it is a thankless job that more often than not chews up and spits people out, then you are probably crazy enough. Trust me. I know what I'm talking about.
So with that out of the way, two pieces of lesser advice:
If you do not already have a college degree, take full (and I mean FULL) advantage of the Army's educational benefits and get one. It will make the whole process a lot easier.
And, keep your record sqeaky clean - no screw ups of any kind (well, no biggies anyway).
Good luck.

It was the best move I made in my career. I disagree with "don't do it for money" that is one large reason I did it. I switched over at 15 years and as an O1E I was treated fairly. My Commander told me and several other Priors that we were held to a higher standard because of our Enlisted service. I was never looked down upon and definitely looked up to by others.
