Army First Sergeant Duties and Responsibilities

In today’s post, I want to talk about some of the most common Army First Sergeant duties and responsibilities.

The First Sergeant is the senior enlisted Soldier in an Army company sized element. A company can range from 50 to 200 Soldiers, depending on the type of unit and its mission.

A First Sergeant normally has 14 to 25-years of military experience. Their job is to work closely with the Company Commander to ensure the unit is trained, proficient, disciplined, motivated, and ready to accomplish its wartime mission. In any unit, the First Sergeant’s duties are endless. The 1SG is normally the first one there in the morning and the last one to leave at night.

From personal experience, I can tell you that the First Sergeant is the backbone of most companies. Look at any successful Army company sized element, and there’s a high likelihood there is a highly motivated, dedicated, and exceptional First Sergeant at the helm. Sure, having a good Company Commander helps, but the First Sergeant’s job is even more important.

In a typical Army company, the First Sergeant’s primary duties and responsibilities include individual training, discipline, Soldier issues, NCO development, and morale.

To keep things simple, the Company Commander typically focuses on “future operations” to include mission planning and strategic work, whereas the First Sergeant focuses on “current operations” handling the day-to-day issues. The commander determines where the unit must go and the First Sergeant makes sure the unit gets there on time.

Top 10 First Sergeant Duties

Here is my list of the top 10 most common First Sergeant duties and responsibilities.

# 1: Individual Training

The First Sergeant is responsible for individual training within their unit. The First Sergeant is responsible to ensure their Soldiers are proficient in their MOS and with their Warrior Tasks.

In essence, their top duty is to ensure their troops are mentally and physically prepared for combat. Their Soldiers must be able to shoot, move, communicate and do their technical job.

The First Sergeant works closely with their Platoon Sergeants and Squad Leaders to ensure the Soldiers receive the training they need to be successful in their jobs, and as Soldiers.

# 2: Administration

Don’t think of the First Sergeant as a pencil pusher. If you’re thinking that right now, drop down and give me twenty good push-ups.

The First Sergeant works with the Readiness NCO, Training NCO, and Company XO to ensure all administrative paperwork is done, done right, and done on time. This includes promotions, awards, reports, routine paperwork, etc.

They don’t necessarily do the paperwork themselves, but they oversee and supervise the process. They also update the attendance roster.

# 3: Enlisted Promotions

The First Sergeant oversees all enlisted promotions in their unit. They recommend potential promotions (up to E-4) to the Company Commander.

In addition, they ensure their NCOs know about promotion opportunities in the unit and outside of the unit. They get input from their subordinate NCOs about who is ready for a promotion and who isn’t. They also teach their subordinates what they need to do if they want to get promoted.

# 4: NCODP

The First Sergeant oversees the unit’s NCODP program. They always look for creative ways to teach and develop their subordinate NCOs. They brainstorm ideas for NCODP, teach classes, and oversee the classes.

# 5: Counseling

The First Sergeant invests lots of their personal time counseling and mentoring the Platoon Sergeants and other NCOs in the unit. They also spearhead the unit’s counseling program to make sure all Soldiers receive the counseling they need and deserve.

# 6: Reenlistments & Retention

Two of the most significant First Sergeant duties are reenlistments and retention. The First Sergeant tracks enlistments and knows when their Soldiers need to reenlist or leave the military. They are very involved with helping their Soldiers make the best decision for their own career.

The First Sergeant also creates an environment where Soldiers WANT to reenlist and continue their military service. Write that one down and remember it!

# 7: Military Schools

The First Sergeant knows which Soldiers need schools and they help their Soldiers get enrolled. They ensure their Soldiers are MOS qualified and also help them get additional schools for career advancement.

# 8: Soldier Discipline

The First Sergeant is the tip-of-the-spear when it comes to soldier discipline. They work with the Platoon Sergeants to handle 99% of the Soldier issues, so they don’t need to get the Company Commander involved. If the issue is serious, they make recommendations to the Company Commander for UCMJ or punitive punishment.

# 9: Health & Welfare

The First Sergeant monitors the health and welfare of their troops. They know about their Soldiers’ family life, their personal problems and their living conditions. They do whatever they can to help their troops.

# 10: Senior Enlisted Adviser

The First Sergeant advocates for their Soldiers and they also serve as the Senior Enlisted Adviser to the Company Commander. This means that the 1SG keeps the Company Commander informed about all Soldier issues and they “keep the Company Commander grounded” from making dumb decisions that negatively affect the Soldiers and unit. This is the First Sergeant’s second most important job, other than preparing their troops for combat.

In a nutshell:

First sergeants handle the leadership and professional development of their Soldiers, especially the non-commissioned officer development and grooming of enlisted soldiers for promotions. They also manage pay issues, supervise administrative issues, recommend and prepare enlisted soldiers for specialty and leadership schools, re-enlistment, career development and they manage the promotable soldiers within the company. First sergeants are the first step in disciplinary actions such as an Article 15 (non-judicial punishment) proceeding. A first sergeant may place a soldier under arrest and on restriction to quarters in certain cases, as well as manage all of the daily responsibilities of running the company/unit. ~ Source: Wikipedia

Key Takeaway

If you get nothing else out of this article, remember that the two most important Army First Sergeant duties are to: (1) accomplish the mission, and (2) take care of their Soldiers.

Additional Thoughts

As you can see, the First Sergeant has an incredibly tough job with lots of responsibilities. These ten things listed above are only a small portion of the potential First Sergeant duties.

These duties might vary a little bit based upon the type of unit, the size of the unit, and the competence of the Company Commander.

The Company Commander and First Sergeant need to work together to accomplish the mission and take care of their Soldiers. All other things come second. Any personality differences must be put aside.

It’s also important to realize that everyone is different. This means that every Company Commander and 1SG will have a different relationship. Based upon the Company Commander’s priorities, their skills, and their relationship, the CO and 1SG might have different priorities and duties than I listed above.

For instance, when I was a Company Commander, my top three priorities were mission planning, collective training and leader development. My First Sergeant’s top 3 duties were individual training, Soldier care, and discipline.

Since we knew each other’s duties and priorities, we stayed in our own lanes and were much more effective. When an issue arose, we knew whose job it was to fix it. That made life much easier for both of us.

history of the army first sergeant

The History of the Army First Sergeant

In the 1780’s, the rank of First Sergeant became a reality in the U.S. Army, but it did not carry the same responsibilities and esteem that it now does. It was in the mid-1800’s when the First Sergeant became a separate pay grade and the diamond was added below the chevrons.

The pay grade for the Army First Sergeant is the same as a Master Sergeant, but in reality, the First Sergeant carries more power. To become a First Sergeant, a Soldier must be a Master Sergeant.

Mistakes to Avoid as an Army First Sergeant

Most First Sergeants are extremely squared away; however, they are human and prone to make mistakes from time-to-time. What you see below is a collection of responses I gathered from former First Sergeants, covering the most common mistakes.

Don’t try to be your Soldiers’ friend. It is in your best interest to NOT go out drinking and partying with your Soldiers and NCOs, ever. Maintain the line. Once you cross that boundary, it’s difficult to go back.

Don’t play favorites. Enforce the Army standards equally to everyone in your unit. This is one of the most common mistakes. We all have coworkers we naturally get along with and admire. Don’t make that mistake. At least, don’t create the perception that you are playing favorites.

Don’t assume… Ask! If you are unsure what your Company Commander wants, ask. If you are unsure what your NCOs and Soldiers need, ask them!

Don’t let your rank go to your head. Keep your ego in check. You’re still human! Be tough, but fair, and consistent. People will respect your rank, but you still must earn their respect.

Don’t act like the rules and standards don’t apply to you anymore. Hold yourself accountable to the same standards you enforce with your subordinates. If anything, hold yourself to a higher standard than the people you lead. Inspire others by your own personal example.

Not passing the Army Physical Fitness Test. This is unforgivable. You may not have the best score, but make sure your APFT and HT/WT are current, and you have the best score you are capable of getting. Always complete your APFT with your unit so there is no question.

Not defending your boss. If you hear your Soldiers badmouthing the Company Commander, or any leader, it is your job to reprimand them. If you disagree with your boss, do it in private behind closed doors. Always be unified with your boss when in front of your troops.

Tips for the Commander & 1SG Relationship

I was fortunate to serve as a Company Commander for two years. I had a great relationship with my First Sergeant. These are a few tips I can recommend to make the command team relationship work.

# 1: Mutual Trust & Respect

The Company Commander and First Sergeant working together is like a marriage. There must be mutual trust and respect for the relationship to work. This means you communicate with each other, keep each other in the loop, look out for each other, and deal with issues as they arise. You are LOYAL to each other and overlook each other’s weaknesses.

# 2: Put the Unit, Mission, & Soldiers First

If you adopt the mindset that the unit, mission, and Soldiers are your biggest priorities, you will succeed in the job. Remember, it’s not about you. Your job is to be the servant leader and serve the people you lead. They don’t work for you. Instead, you work for them.

# 3:  Establish Unit Goals

The commander and First Sergeant should sit down together at the beginning of the relationship and establish clear goals for the unit. This is primarily the Company Commander’s responsibility, but the Company Commander should get input from the First Sergeant. Ultimately, you want the 1SG and Commander unified about the company’s goals.

# 4: Establish Lanes

Both the First Sergeant and Company Commander need to stay in their lane. The only way this will ever happen is if the Company Commander and 1SG sit down and determine who is responsible for what. Know your lane and stay in your lane. This will eliminate 90% of your potential problems.

# 5: Help Fill In the Other Person’s Weaknesses

No one is perfect. Everyone has shortcomings, even the First Sergeant (just don’t tell them I said that). Figure out where your Company Commander is weak, and find ways to fill in the gap. Have your Company Commander and Platoon Sergeants do the same thing with you. For example, if the 1SG isn’t good at admin, he can delegate a lot of it to others around him who are good at it.

# 6: Be Unified

Your must be unified with your Company Commander, even if you don’t like them as a person. The mission and Soldiers must come first, no matter what. Be loyal to each other and have each other’s back at all times, especially when you are in front of your Soldiers. If you have issues, work them out in private, behind closed doors.

These things are easy to do and easy not to do. What you do is your decision!

The First Sergeant is the highest ranking non-commissioned officer that still performs “hands-on” leadership in the United States Army. The importance of the position is exemplified in a phrase used in the German Army, they call the First Sergeant the “Father of the unit”. This is just as true in the U.S. Army. Although equal in grade to rank of master sergeant (MSG), personnel at these two ranks typically have very  different responsibilities. ~ Army Facts

Suggested Reading

If you’re about to become an Army First Sergeant, or you are already in the job and looking to level up your performance, here are a few books I recommend. The first one is Small Unit Leadership by Dan Malone. This is easily my favorite book for company level leaders. Order this book, read it, and study it. The second book is The Three Meter Zone, which is a great book to read along with your NCOs for a NCDOP.  If you click on either of the links you will redirected to my Amazon store.

Final Thoughts

In conclusion, serving as an Army First Sergeant is quite perhaps the most demanding and best job in the Army. If you ever get the opportunity to serve as a First Sergeant, make sure you do your best! Your Soldiers deserve great leadership.

  1. Served as 1SG for 6yrs 82d Abn div most rewarding job I’ve ever had,some of the best officers nco’s in the army everybody mission and soldier oriented when a soldier had a problem beleive me it was taken care of all ways take care of your soldiers keep yourself physically fit and morally straight and young 1SG you will truly be appreciate by your unit and the airborne all the way and a little further.

    1. Thanks for your service, Charlie. I have a tremendous respect for the 82nd Airborne and all the soldiers, NCOs and officers, past and present. I’m glad you had a great experience leading your unit. Here’s to the next chapter of your life!

  2. I served as a 1SG for seven years. During my service, I developed a positive relationship and understanding with my Company Commander (CO). This relationship and understanding was based on a philosophy that the CO commanded the Company and I ran it. By that, I mean that the CO would tell me company objectives and I would ensure that they were met. I would ask for a copy of the CO’s Officer Efficiency Report (OER) Support Form, upon arrival at a new assignment, and I would advise and ensure the objectives were met. Using this tool, I was able to concentrate on the CO’s plan and direction for the Company.

    Daily interactions helped to keep both of us informed and on tract. We did have disagreements, but the CO was receptive to listening to my concerns and suggestions. Regardless of the CO’s decision, I left and implemented the final decision as if it was mine! No grumbling or disrespect, the mission is the responsibility of the CO, mine was to execute!

    Information is a two way street. Therefore, I held a platoon sergeants meeting each morning prior to physical training (PT) formation. I would outline and assign responsibilities for daily and upcoming events. The platoon sergeants would alert me to their necessary support requirements to accomplsh the mission.
    We would discuss, in a round robin forum, soldier welfare to include; health, family, promotion and school eligibility, mock promotion preparation boards boards, financial problems, requirements for both good and bad performance soldier councilings, and other soldier issues.

    I would allow soldiers who committed small infractions to choose, UCMJ action, or what I referred to as first sergeant time (two hrs. of after normal duty hour company benefit duty, discussed first with the platoon sergeant & CO). Still getting the soldiers attention without destroying a career. I always gave the benefit of the doubt to the soldier, at least the first time.

    I visited the clubs my soldiers frequented, both on post and off. Furnishing the managers my name, unit, and phone numbers, so if any of my soldiers were involved in an minor incident, to contact me instead of MPs or local law enforcement. I promised to provide restitution for any damages (the soldier, with sufficient evidence). When summed by law enforcement to retrieve a soldier, I would require the platoon sergeants & when appropriate the squad leader to meet me at the location to ensure we all got the same story. Platoon leaders could also attend, but were required (per the CO) to remain silent and just listen while in the presence of the soldier or law enforcement.

    We had platoon competitions in PT, Drill & ceremony (D&C), marksmanship, skill qualification test (SQT), and common tasks (CT). Platoons that won were given a training day, which allowed the platoon to engage in a platoon chosen activity of their choosing, but in which all platoon members must participate (accountability was required prior to and after the event). Family members could participate in select activities with the soldier’s and platoon sergeant’s approval. Soldiers and family members were always recognized when in the hospital or upon a family member death.
    These are a few of the principals that worked for me and we’re successful to rise to the top of the battalion in every category. Suggest 1SGs empower their platoon sargeants, reward as well as discipline their soldiers, and stay loyal to their CO, soldiers, themselves, and those who count upon them!

    1. It is my opinion that anyone who is about to become a first sergeant should read your advice.

      I like your approach and I am sure that your soldiers respected you in many ways.

      If all First Sergeants would use a similar approach, we would have a very solid force, but many follow other patterns.

      I believe the key is not playing favorites and working with the Company Commander as a team.

      Thanks for sharing all of that.

  3. I know the duties and responsibilities of Army First Sergeant. Because my father server as 1SG for 5 years in US Army. It is very tough job and you need to pass from very up and downs and fulfill the above requirements as you duty.

  4. A 1SG can certainly make or break the morale of his unit.

    It’s his job to be close to the soldiers and help them be ready. Sometimes that means tough love, but tough love should never be abused.

    Other times it means simply checking with each individual and asking if they are ready and have everything.

    A good 1SG is priceless to a unit.

  5. We recently got a new commander and 1SG. Short words, 1SG shouldn’t even be a SGT. Anyways, my company recently went to the field and I couldn’t go because I am currently getting med board, my 1SG was very upset because he couldn’t make all the profiles go, and for that matter he made us stay in the company building and spent the night there, by the way, the company area was infested with roaches. The bad part about it was that he said since we cant go to the field we are going to be cleaning the building. All of us knew he was punishing us just because we were on profiles and he couldn’t count us as part of his training to meet his required number.

    One of the soldiers came to me the following day and told me 1SG have been talking about me inside the tent, and in front of everyone saying that he will give me an article 15, how bad of a soldier I am, and he will do his best to get me chapter out and not med board. All of this came into place just because I was the only one at the time who actually stood up and told him he was wrong for what he was doing. 1SG is the type of person who is never wrong, you can’t be against him or else, he threats everyone with promotions if they do not do as he please, ex: FRG meetings are not in the training schedule, he forces us to go and tell us he will give us a counseling statement if we do not attend his functions, well, he did. He also said if you think you are going to get promoted in this unit you might want to think twice. Personally, I just wanted to know which part of the regulation states 1SG and commanders are not allow to expose soldiers business to others who do not need to know. I have read AR 340-21 and couldn’t make sense of it, please help me.

    1. I’m sorry to hear you have to go through this. Your private information is protected by HIPPA, but the idea of the 1SG simply saying bad things about you in front of other soldiers is quite unprofessional. I suggest you use you Commander’s Open Door Policy and have a conversation with them.

  6. Just a tidbit on discipline. It is important for leaders especially 1SG’s to understand the unintended consequences of their recommendations when it comes to discipline. Currently the Army is in the midst of a major drawdown. As such a Soldier receiving a poor evaluation report (needs improvement, No comment, or 4-5 rating) and/or a Soldier receiving an Article 15 is pretty much guaranteed to be separated from service. Therefore leaders must seriously think about what actions are appropriate given the situation. If the issue is minor in nature or can be best handled with corrective training, a verbal counseling, formal counseling, local letter of reprimand….don’t recommend an Article 15 as this will most likely remove your ability to influence the retention of the Soldier at some point in the future as these decisions will be made by more senior leaders based on Army policy.

    1. You’re right, in today’s Army a bad NCOER or Article 15 can ruin someone’s career. I always tell leaders to put some serious thought into their serious decisions, so they can make the right decision. You don’t want to make a rash decision that you will go on to regret later.


    2. Candace Ginestar

      On the flip side, some leaders are too afraid to discipline when the Soldier needs it. I agree, see if things can be handled in a lesser format than Article 15 when possible. There are a lot of ways to correct a Soldier, but sometimes more is needed.

  7. Knowing the duties of any position is important and this post does a good job of highlighting the top ten duties of the First Sergeant. Non-military folks have a hard time understanding all the various responsibilities and sometimes it is hard to explain. You have laid it all out here in an easy to understand format. Working with the Readiness NCO and Training NCO is important.

    1. Katelyn Hensel

      I agree. For those of us who have grown up without a military background, it’s difficult to keep all of the rankings and positions straight. I’m trying to understand for my fiance’s sake, but even though I grew up in a family full of the military lifestyle, I never seemed to pick up on what each rank did. I feel like Re-enlistments and retention would be a huge issue though. Important for our country, and for our service.

  8. Good post for both Company Commanders AND Platoon Leaders. It is always good to have a strong working relationship with your Company 1SG as a PL. Remember, your PSG reports to him AND you. If you understand what the 1SG expects and how he works things, there is less of a chance that you two will butt heads…

    1. So true. The key to success is to build strong relationships. That means you need to talk, listen to each other and get on the same sheet of music. Most new Platoon Leaders struggle to do this with the 1SG as they figure out their role, responsibilities and leadership style. But the smart Platoon Leaders do what they can to work with the First Sergeant, because they know he is the one who can “influence” the commander more than anyone else.


    2. Communication is always the main factor. This was an excellent post and I hope many Company Commanders and 1st Sergeants read it. If everyone who has a leadership position can communicate and get on common ground, the company will be successful and everyone within will be happy for the most part. When there is division, it causes chaos and things will fall apart.
