Introduction: What Is a Warhammer Army?
If you are new to Warhammer, one of the first terms you will encounter is “army.” It appears everywhere in beginner guides, starter set descriptions, faction overviews, and product listings. New hobbyists often ask the same question: what is a Warhammer army, and how is it different from just owning a few miniatures?
The simple answer is that a Warhammer army is a group of miniatures chosen to fight together under the rules of a specific game system. It is the force you collect, build, paint, and command on the tabletop. In Warhammer 40,000, that might mean a Space Marine strike force, a Tyranid swarm, or a Thousand Sons host. In Warhammer Age of Sigmar, it could be a Stormcast Eternals army, an Orruk warclan, or a Soulblight Gravelords force.
For beginners, understanding the idea of an army is important because it shapes almost every purchase and hobby decision you make. It affects which miniatures you buy, what rules you use, how you paint your models, and how you grow your collection over time.
This guide explains exactly what a Warhammer army is, how it works in simple terms, how beginners should choose one, and which products make the best starting point. If you want a clear and practical answer to the question “what is a Warhammer army?”, this article will give you a complete foundation.
Definition: What Is a Warhammer Army?
A Warhammer army is a collection of miniatures that belong to the same faction or alliance and are used together in tabletop battles according to the game’s rules.
That is the clearest definition for beginners. A Warhammer army is not just a random set of models. It is an organised force built to follow the rules of Warhammer 40,000 or Warhammer Age of Sigmar.
In practical terms, a Warhammer army usually includes:
- Core units that make up the main body of the force
- Characters or leaders that support or command the army
- Specialist units with unique battlefield roles
- Sometimes vehicles, monsters, or elite troops depending on the faction
Short quotable explanation: A Warhammer army is the set of miniatures you use together as one playable force on the tabletop.
Another simple definition: Your army is your team in Warhammer. It is the faction you collect and the force you command in battle.
What Makes a Warhammer Army Different from a Single Miniature?
A single miniature is one model. A Warhammer army is a coordinated group of models that work together in a game.
This distinction matters because many new hobbyists buy one box they like the look of, then realise they also need a wider force if they want to play full games. One miniature or one unit can be part of an army, but it is not the army by itself.
For example, a box of Space Marines Primaris Intercessors gives you a troop unit. That is a useful building block, but it is only one part of a wider Space Marines army. Likewise, a box of Thousand Sons Rubric Marines is a key unit for Thousand Sons players, but it does not automatically become a full army on its own.
Think of it this way:
- A miniature is one model
- A unit is a group of miniatures that fight together
- An army is the full force made from multiple units under one faction
Short quotable explanation: A miniature is one model. A unit is a game-ready group. An army is the complete force.
Beginner Explanation: What a Warhammer Army Means in Simple Terms
If you are completely new, the easiest way to understand a Warhammer army is to compare it to picking a side in a strategy game.
When you play Warhammer, you do not just move random figures around. You choose a faction, such as Space Marines, Tyranids, Stormcast Eternals, or Thousand Sons, and build a force from that range. That force becomes your army.
Your army is the part of the hobby that becomes “yours.” It is your chosen faction, your painted colour scheme, your collection, and your playstyle.
For many people, the army is also the emotional centre of the hobby. It is the thing they gradually expand over time. They start with a few models, learn the rules, add new units, improve their painting, and eventually field a larger and more complete force.
In simple language:
- Your Warhammer army is the group of models you collect for one side
- It is the force you use in battles
- It grows as you add more units
- It reflects your tastes in gameplay, lore, and model design
That is why army choice is one of the biggest decisions for any beginner.
How Warhammer Armies Work in the Game
Armies Are Built Around a Faction
Most Warhammer armies are built around a faction. A faction is the in-universe group your models belong to. In Warhammer 40,000, examples include Space Marines, Tau Empire, Tyranids, World Eaters, and Thousand Sons. In Age of Sigmar, examples include Stormcast Eternals and many other fantasy forces.
Each faction has its own:
- Model range
- Rules
- Playstyle
- Background lore
- Visual identity
That means your army is more than a pile of miniatures. It is a themed force with shared rules and a distinct battlefield identity.
Armies Are Made of Units
You do not usually field models one by one. Instead, armies are made of units. A unit may be a squad of infantry, a single character, a vehicle, or a monster. These units interact with each other on the battlefield.
For example, a beginner Space Marines army might include:
- A leader character
- A battleline or troop unit
- An elite unit
- A mobile or ranged support option
That structure gives the army balance and helps you learn different parts of the game.
Armies Usually Follow Points or List-Building Rules
In most games, Warhammer armies are built to a points limit or similar army-building framework. Each unit has a cost, and you choose units until you reach the agreed game size.
Beginners do not need to master competitive list-building straight away. The important thing to understand is that a Warhammer army is usually assembled according to official rules, not chosen at random.
Short quotable explanation: A Warhammer army is a legal, playable force built from units within one faction’s rules.
Warhammer 40,000 Armies vs Age of Sigmar Armies
When people ask what a Warhammer army is, they may be talking about two different main systems: Warhammer 40,000 and Warhammer Age of Sigmar. The idea of an army is similar in both, but the settings and factions are different.
Warhammer 40,000 Armies
Warhammer 40,000 armies are set in a dark science-fiction universe. Armies often feature advanced weapons, futuristic armour, alien species, daemons, and war machines.
Popular 40K army themes include:
- Space Marines for elite flexible troops
- Tyranids for swarm-style alien aggression
- Tau Empire for ranged firepower
- World Eaters for brutal melee combat
- Thousand Sons for sorcery and elite infantry
Warhammer Age of Sigmar Armies
Age of Sigmar armies are set in a high-fantasy universe. These forces often feature magic, monsters, heroic champions, and mythic themes.
Popular Age of Sigmar army themes include:
- Stormcast Eternals for durable warrior heroes
- Undead forces for gothic fantasy themes
- Orruks and destruction armies for aggressive combat
- Chaos factions for dark fantasy power
Which Type of Army Is Best for Beginners?
Neither is objectively better for every new player. The best choice depends on what excites you more.
- Choose Warhammer 40,000 if you prefer sci-fi, guns, aliens, and futuristic warfare
- Choose Age of Sigmar if you prefer fantasy, magic, monsters, and mythic armies
A great first step is to start with an introductory set for the setting you prefer. The Warhammer 40,000 Introductory Set is ideal for beginners who want to enter 40K, while the Warhammer Age of Sigmar Introductory Set is a strong entry point for fantasy players.

What Is Included in a Beginner Warhammer Army?
A beginner Warhammer army does not need to be huge. In fact, starting small is usually the smartest approach. New players often assume they need a giant collection immediately, but that is not true.
A practical beginner army often includes:
- One leader or character
- One or two basic troop or infantry units
- One more specialised unit to add variety
- The rules and accessories needed to play beginner games
This is why starter products are so useful. They give new players a manageable entry point instead of forcing them to build an army from scratch with no direction.
Starter sets are especially helpful because they:
- Reduce decision fatigue
- Provide a ready-made beginning force
- Include beginner-friendly missions or rules
- Offer better value than buying everything separately

How to Choose Your First Warhammer Army
Choose the Army You Like the Look Of
The most important beginner rule is simple: choose the faction you actually like. You will spend time building, painting, and learning that army, so the models should genuinely appeal to you.
If you love the look of futuristic super-soldiers, Space Marines may be a natural fit. If you prefer sinister sorcerers, Thousand Sons Rubric Marines might be more exciting. If you like heavy alien monsters, a Tyranid force built around creatures such as the Tyranids Winged Hive Tyrant may be the direction you want.
Choose Based on Playstyle
Different armies feel different on the tabletop. Even beginners benefit from understanding the basics:
- Some armies are durable and forgiving
- Some rely on speed and aggression
- Some specialise in ranged attacks
- Some are elite, with fewer but stronger models
- Some use magic or psychic-style mechanics heavily
You do not need to become an expert before choosing, but a rough understanding helps you avoid buyer regret.
Choose Based on Simplicity
Some armies are easier for new players to learn than others. Straightforward infantry-heavy armies can be less overwhelming than highly technical forces with unusual mechanics.
That does not mean you should avoid a faction you love. It simply means that if two armies appeal equally, the simpler one may offer a smoother first experience.

Starter Sets vs Building an Army Unit by Unit
Why Starter Sets Are Usually Better for Beginners
Most new players should start with a boxed beginner product rather than assembling a full army one kit at a time. Starter sets are designed to teach the hobby in stages. They also remove much of the uncertainty that new customers face.
A starter set usually gives you:
- A first group of miniatures
- Basic rules
- Gameplay accessories
- A clear first step into the hobby
The Warhammer 40,000 Introductory Set is especially useful because it provides a clean introduction to how armies and units work in practice. Likewise, the Warhammer Age of Sigmar Introductory Set is a strong option for players drawn to the fantasy setting.
When Individual Kits Make Sense
Buying individual kits makes more sense once you know what faction you want and how you plan to expand. For example, after learning the basics with a starter product, a Space Marines player might add units such as:
These units help shape the identity and tactics of a growing army. But for absolute beginners, it is usually easier to start with a set that teaches the foundations first.
Do You Need to Paint a Warhammer Army?
You do not strictly need to paint your army to understand the game, but painting is one of the core parts of the Warhammer hobby. For many players, their army only truly feels like their own once it is built and painted.
Painting also makes it easier to:
- Feel invested in your faction
- Recognise your units during games
- Enjoy the hobby outside of play sessions
- Create a more immersive tabletop experience
Beginners should not be intimidated by this. You do not need professional painting skills to start. A simple paint set and a few basic techniques are enough to begin.
Good beginner options include the Warhammer 40,000 Paints and Tools Set and the Warhammer Age of Sigmar Paints and Tools Set.
For step-by-step help, see How to Paint Warhammer Miniatures.
How Big Does a Warhammer Army Need to Be?
One of the most common beginner misconceptions is that a Warhammer army has to be massive. In reality, army size depends on the kind of games you want to play.
Some players enjoy small introductory games with only a modest number of models. Others gradually build toward larger armies for bigger battles.
Short quotable explanation: A Warhammer army does not need to start large. A small, playable force is the best place for most beginners to begin.
Starting small has several advantages:
- Lower upfront cost
- Less pressure to assemble everything at once
- Faster route to playing your first games
- More manageable painting workload
- Easier learning curve
This approach is especially useful if you are still deciding how deeply you want to invest in the hobby. For cost expectations, read Is Warhammer Expensive.
Examples of What a Warhammer Army Can Look Like
Warhammer armies vary massively in theme, size, and playstyle. Here are a few simple beginner-friendly examples.
Example 1: A Space Marines Army
A Space Marines army often includes durable infantry, elite warriors, and strong leadership. It is one of the most common beginner choices because the models are iconic and the faction is broadly supported.
A growing Space Marines collection might include:
- Basic infantry such as Space Marines Primaris Intercessors
- Elite units such as Terminators or Bladeguard Veterans
- Specialist support choices added later
Example 2: A Thousand Sons Army
A Thousand Sons army is smaller in model count than some factions but rich in style and theme. It is ideal for players who like ornate miniatures, chaos aesthetics, and psychic or magical flavour.
A key example unit is Thousand Sons Rubric Marines, which form the visual and gameplay backbone of many Thousand Sons forces.
Example 3: A Tyranid Army
A Tyranid army often feels alive and aggressive. It can range from swarms of smaller organisms to towering bio-monsters. That makes it especially attractive to players who want a dramatic alien aesthetic.
A standout monster option is the Tyranids Winged Hive Tyrant, which shows how armies can be built around both core units and impressive centrepiece models.
Practical Guidance for Beginners Starting Their First Army
Step 1: Pick a Setting
Decide whether you prefer Warhammer 40,000 or Age of Sigmar. This choice narrows the field and makes every later decision easier.
Step 2: Pick a Faction You Genuinely Like
Choose based on appearance first, then consider playstyle. It is much easier to stay motivated when you love the look and theme of your army.
Step 3: Start with a Beginner Product
Starter sets are usually the easiest entry point because they give you a ready-made launchpad. They also help you avoid buying scattered products without a plan.
Step 4: Build and Paint in Small Batches
Do not overwhelm yourself by trying to finish a giant army immediately. Build a few models, paint a few models, then continue in stages.
Step 5: Learn Through Small Games
You do not need a tournament-ready force to start enjoying the hobby. Small introductory games teach the basics faster than buying too much too soon.
Step 6: Expand with Purpose
Once you know how your army works, add new units that support the style you enjoy. That is a much better approach than impulse-buying random kits.

Common Mistakes Beginners Make When Building a Warhammer Army
- Buying too many models before learning the basics
- Choosing a faction only because it is powerful rather than personally appealing
- Ignoring starter products that simplify the first steps
- Starting with overly complex expansion plans
- Feeling pressure to paint everything perfectly
- Mixing unrelated units without understanding army rules
Most of these mistakes come from rushing. The best beginner strategy is steady progress. A Warhammer army is usually built over time, not in a single purchase.
FAQ: What Is a Warhammer Army?
What is a Warhammer army?
A Warhammer army is a collection of miniatures from the same faction or alliance that are used together as one force in tabletop battles.
Is a Warhammer army the same as a faction?
No. A faction is the broader group or identity, such as Space Marines or Thousand Sons. Your army is the specific force of models you collect from that faction.
How many miniatures are in a Warhammer army?
There is no single number. Small beginner armies may only use a modest number of models, while larger armies can include many units. The right size depends on the game format and your goals.
Can I start Warhammer with only one unit?
You can start collecting with one unit, but a single unit is not usually a complete army. Most beginners are better served by a starter set or a small planned force.
What is the best first Warhammer army for beginners?
The best first army is usually the faction you like most visually and thematically. Many beginners start with accessible and popular ranges, then grow from there with starter products and basic troop units.
Do I need to paint my Warhammer army before playing?
No, painting is not always required for casual learning games, but it is a major part of the hobby and makes your army feel more complete and personal.
Should I buy a starter set or individual units first?
Most beginners should buy a starter set first because it gives a more guided, cost-effective, and playable starting point than choosing individual kits without experience.
Can I mix different factions in one Warhammer army?
That depends on the rules of the specific game and format. In general, beginners should focus on one faction first because it is simpler to collect, paint, and learn.
Is building a Warhammer army expensive?
It can become expensive over time, but beginners can control costs by starting small, choosing one faction, and expanding gradually rather than trying to collect everything at once.
Conclusion: Your Warhammer Army Is the Heart of the Hobby
A Warhammer army is more than a group of miniatures. It is your faction, your collection, your playstyle, and your long-term hobby project. It is the force you build, paint, learn, and gradually expand as you become more confident in the world of Warhammer.
For beginners, the most important thing to remember is that your first army does not need to be huge or perfect. It just needs to be a force you are excited to start. The best first step is often a beginner-friendly starter set, followed by a few carefully chosen additions that match the faction you love most.
If you want the easiest route into Warhammer 40,000, the Warhammer 40,000 Introductory Set is a strong place to begin. If fantasy appeals more, the Warhammer Age of Sigmar Introductory Set offers a clear starting point. From there, you can expand into infantry, elite units, characters, and hobby supplies at your own pace.
Once you understand what a Warhammer army is, the hobby becomes much easier to navigate. You are no longer just buying miniatures. You are building a force with identity, purpose, and personality. That is what makes Warhammer so rewarding for new and experienced players alike.
