Executive Summary of Officer Ranks and Titles in the US Military
Let’s make an executive summary of the officer ranks and titles for all branches of the US military. Officer ranks are designated as O for Officers and are numbered between 1 and 10, with 1 being the youngest officer and 10 being the most senior officer
Company Grade Officers: O1 to O3
- O1 to O3 are considered company-grade officers because they generally work at the tactical or company level. They are generally in harm’s way more often, directly fighting or providing direct support
Field Grade Officers: O4 to O6
- O4 through O6 are called field grade officers. These officers work at the operational level and have an indirect influence on the tactical battlefield. They are the orchestrators.
Flag Officers or General Officers: O7 to O10
- 07 to 010 are called flag officers or general officers. The reason they are called flag officers is because they have a flag that flies with them or is posted wherever they go.
- For example, if you are a one-star army officer, you will have a red flag with one silver star. If you are an Air Force two-star general, then you will have a blue flag with two silver stars.
Leadership and focus
My general observation is that any flag officer who actually cares about flying his or her flag is a major tool. The best generals and the best admirals I’ve ever worked with don’t care much about silly things like putting their flags up in the right spot before a meeting. They simply care about leading.

Army Officer Responsibilities & Duties
Today we will talk about what army officers do. We will cover the top 12 most common things and the most common duties that army officers are responsible for. So if you’re thinking about becoming an army officer or a brand new officer and wondering what you should do, this post is for you.
I have narrowed it down to the 12 things that will take up 90 % or more of your time. First, however, remember that, as an officer, you are responsible for everything that happens and doesn’t happen in your unit.
Army Officer Duty 1: Mission Planning
Mission planning: Army officers are responsible for mission planning, which involves coming up with operation orders, troop-leading procedures, and military decision-making processes. They focus on missions that are 30, 60, or 90 days out.
The biggest difference between an officer and an NCO is that the former is focused on the future, whereas the NCO handles the day-to-day. For example, in the business world, the officer is more like the CEO, and the NCO is more like the Vice President of Operations, who runs the day-to-day activities. The CEO determines where they want the organization to go; that’s what Army officers do. Army officers also
- Plan missions
- Come up with operation orders.
- Go through the troop-leading procedures of the military decision-making process,
- They are focused on missions that are 30, 60, or 90 days out.
When Army officers get a mission or a task from a higher headquarters, they formulate a plan for their unit, whether they are generals or brand-new lieutenants. They are coming up with a plan for our platoon; they are the mission-planning experts in their platoon.
In summary, this army officer’s duty means they come up with the plans, the NCOs supervise those plans, and the soldiers execute those plans.
Army Officer Duty 2: Collective Training
Collective training: Army officers ensure that their unit is proficient in collective tasks, which involve tasks that groups such as squads, fire teams, platoons, or companies do as a whole.
In the army, you have individual training in shooting, moving, and communicating. The NCOs are in charge of that. Then you have collective training. Collective training is a task that we do as groups. It could be what a squad, a fire team, a platoon, or a company does as a whole. It’s their wartime mission. It is what they do as a complete organization.
For example, there is a soldier named Johnny who is shooting, and another guy is moving, but they’re all working together, which is their collective task.
Army officers have a duty to ensure their unit is proficient in their collective tasks. Each organization lists collective tasks based on its mission and what unit it is; an army officer is responsible for ensuring their unit is trained in those tasks.
Army Officer Duty 3: Leader Development
Leader development: Army officers are responsible for their own professional development and the development of subordinate officers and NCOs.
Army officers are responsible for developing themselves, so we need to ensure our subordinate officers and NCOs are getting their professional development. They’re getting the schools that they need, and they’re getting the mentoring and counseling that they need.
In many cases, as army officers, we’re doing this ourselves. In other cases, we’re making sure it gets done. We typically develop leaders up to two levels down, mainly with the people we directly supervise, and then we make sure they’re supervising, mentoring, leading their people, and so forth.
Army Officer Duty 4: Develop policies and procedures
Develop policies and procedures: Army officers, particularly commanders, develop policies and procedures for their units, such as unit SOPs, tactical SOPs, and policy letters.
Now, not all officers will develop policies and procedures. This is usually reserved for commanders, but sometimes a staff officer or another officer could end up developing one. These are unit SOPs, tactical SOPs, policy letters, and other things that an officer would come up with and sign, typically done by a unit commander.
Army Officer Duty 5: Enforce Army Standards
Enforce army standards: Army officers are responsible for enforcing army standards, setting an example, and correcting issues when they arise.
Now, I’ll be honest with you: most of the time, the NCOs have this covered. They’re working with the privates and the specialists in the private first class, ensuring that when they mess up, the standards are being enforced.
But we, as officers, have responsibilities, too. We need to make sure that we are following Army standards as officers. We also need to make sure that our subordinate officers and NCOs are enforcing the standards and living by them.
So we set the example: when we see something wrong, we fix it. Now, there’s a right and wrong way to do this. I’ve always believed that when something is wrong, you can pull the person aside privately and knock it out.
Regardless of how you handle it, it is your job as an officer to enforce the standards. If you let things slip by and see something wrong and don’t correct it, you’re doing a disservice to your unit and your soldiers.
Army Officer Duty 6: Tacticians
Tacticians: Army officers are responsible for tactical decision-making and leading units in the field.
I was told long ago that the quickest way to find out if you have a good officer is when you go to the field. In most cases, NCOs run the show in garrison, but in combat, in the field, or in a tactical situation, that’s really where officers make their money.
If they’re in a combat unit, you’ll find out quickly how good or bad your officer is when you go to the field because that’s where they make their money. That’s where they shine, or that’s where they collapse.
Army Officer Duty 7: Property Accountability
Property accountability: Army officers are responsible for property accountability, including maintaining and inventorying equipment.
In most cases, as an Army officer with a primary hand receipt holder, we are responsible for ensuring that people are safeguarding their equipment. They’re maintaining their equipment. This includes removing excess equipment, replacing damaged equipment, and ensuring inventories are done on time and to standard.
Army Officer Duty 8: Mission Accomplishment
Mission accomplishment: Army officers ensure that their units accomplish their missions on time and to a high standard.
When your unit accomplishes its mission, your boss will look at you. Your boss will look at you when your unit fails to accomplish its mission. You are responsible for ensuring the mission gets done on time, to standard, and, ideally, with no setbacks or issues.
This includes your job as an officer and everyone working under your authority. Everything in the Army is about mission accomplishment.
Army Officer Duty 9: Supervision
Supervision: Army officers supervise NCOs and soldiers, leading anywhere from a few to a few thousand people.
As an officer, you will be a supervisor. Depending on your duty position, you will typically lead an NCO, a staff sergeant, or someone above. So you could supervise anywhere from a few to a few thousand people.
Army Officer Duty 10: Readiness
Readiness: Army officers are responsible for ensuring their units and soldiers are ready to deploy at a moment’s notice.
The army is not only about its mission but also about readiness. You want to make sure your equipment is ready to deploy at a moment’s notice. Likewise, you need to make sure that your soldiers are prepared to deploy at a moment’s notice.
You must ensure your unit is trained for its wartime task. That is what readiness is. Everything affects readiness.
- Are soldiers getting their physical fitness?
- Are they MS-qualified?
- Are they getting the schools they need?
- Is your equipment PMCS-compliant?
- If the equipment is on deadline, is it getting fixed?
All of those things affect unit readiness. So you’ll spend a lot of time on this one, especially when you’re at the small unit level, company level, and below.
Army Officer Duty 11: Leadership and Management
Leadership and management: Army officers are responsible for leading and managing tasks, setting the tone for their organization, and empowering others.
As officers, regardless of our position, we are in a leadership role; the buck stops with us.
- We are responsible for setting an example.
- We are responsible for managing tasks and leading people.
- We command units.
- We lead the staff.
- We lead sections.
- We set the tone for our organization
- We supervise.
- We delegate.
- We empower other soldiers.
When you think about a leader you work with in any capacity, that’s what you will be doing as a leader in the army.
- You inspire people.
- You make tough decisions.
- You accept responsibility when things go wrong.
- You give credit when things go right.
- You make sure things go right.
- You make sure that the plan is done.
- You handle issues.
- You put out fires.
- You deal with soldiers’ problems.
All of those things fall under leadership and management.
Army Officer Duty 12: Soldier morale
Soldier morale: Army officers are responsible for monitoring and addressing soldier morale, working closely with their NCOs.
This is the last one we will cover in this post. Ultimately, as an Army officer, you are responsible for soldier morale. Your NCOs will have a significant impact on the morale of your unit. But as an officer, it’s your job to spot-check that.
If there’s an issue, it’s your job to identify and fix it. You will work closely with your NCO. Some people call this a spree to the core.
You want to ensure your soldiers have the skill and the will to do their job and, more importantly, the resources to do it so they’re satisfied and content.
You should be monitoring retention in your unit. If everybody is ETS or getting out, there’s probably a moral problem. If the performance is low, there’s a morale problem. Morale always starts at the top and works its way down.
So if there’s a morale problem, it’s your fault, directly or indirectly, and you must ensure it gets fixed.
Army officer responsibilities
As listed above, these are just 12 duties you will get as an army officer. Being an officer is fun, challenging, and exciting. I’ll be the first to admit that sometimes you scratch your head, especially when you’re brand new, and you’re like, What did I get myself into? But you will figure it out as you mature, gain experience, and learn from your NCOs.
You will learn, figure things out, and be very good at what you do, even if you don’t start that way.
Being an army officer is an honor. It’s a privilege. It’s a tough job. But it prepares you for just about anything in life. If you can succeed in this type of job, you can succeed easily in the civilian and private sectors.
If you are thinking about becoming an army officer, I highly encourage it. It’s a great career. It’s a great stepping stone to other things that you can do in your life. And if you have been an officer before, I would love it if you commented below and talked about some of the things you did and some of your most common duties, just in case I missed something.
Army Officer Salary & Ranks Conclusion
Okay, there you have it. An executive summary of the commissioned officer ranks, titles, salary, duties, and responsibilities. It was a privilege to have served my entire career as a US Army commissioned officer, leading some of the best men and women of the army in the special operations community.
Although I retired as a Major and made my largest contribution to global security as a major, for sure, I had the most fun as a captain and would love to be given an opportunity to go back to do it all over again.
Thanks for reading.
