Overall, these ten units are just some of the many powerful and iconic space marine units that can be fielded in Warhammer 40k.

Each unit has its own strengths and weaknesses, so players must carefully consider their army composition and strategy to maximize their chances of victory.


10) Devastator Squad

Datasheet

The Devastator Squad is a heavy weapons team that can lay down a significant amount of fire against enemy infantry and vehicles.

They are equipped with a variety of weapons, including heavy bolters, lascannons, and missile launchers.

One of their primary roles in battle is to provide heavy fire support for other units, allowing them to make advances while the Devastator Squad holds down enemy forces. With their ability to neutralize both ground and air targets, they are crucial in maintaining battlefield dominance.

What makes a Devastator Squad so useful is their ability to be tailored to fit any situation. They can be configured in a number of different ways, providing a level of versatility unmatched by other units. For example, they can be equipped with anti-tank weapons to take out enemy vehicles, or anti-infantry weapons to hold off waves of enemy troops.


9) Biker Squad

Datasheet

Biker Squads offer unparalleled mobility on the battlefield. They are able to quickly traverse any terrain and reach their target with ease, making them the perfect unit for hit-and-run tactics. Moreover, they can easily outflank enemy units and attack from unexpected angles, which can hugely disrupt enemy strategies.

They are incredibly tough and resilient thanks to their power armor and bike-mounted shields. This means they can absorb a lot of enemy firepower, allowing them to survive even in the face of heavy resistance. Additionally, they have a high toughness value which makes them more resistant to certain types of attacks, such as rending or poison.

Biker Squads excel at ranged combat, making them ideal for harassing enemy units or taking out high-value targets. They are armed with a range of weapons, including bolters, plasma guns, and meltaguns, which can deal significant damage to enemy units. Their bikes also have twin-linked weapons, meaning they can unleash a hail of fire on the enemy.

As well as exceptional mobility, Biker Squads are more than capable in melee combat. Their close combat weapons, such as chainswords and power swords, are highly effective against enemy infantry and can easily carve through even the toughest of foes.


8) Librarian

Datasheet

This Space Marine unit is a psychic powerhouse that can bring a wide range of abilities to any battle. The Librarian’s primary function is to cast psychic spells that can be used to buff friendly units or debuff enemy units. This makes them an invaluable asset on the battlefield.

For example, the Biomancy discipline can be used to boost the Librarian’s own physical abilities or buff friendly units, while the Telekinesis discipline can be used to manipulate the battlefield and throw enemy units around.

Another reason why Librarians are so useful in Warhammer 40k is their ability to deny enemy psychic abilities. This means that if an enemy psyker attempts to cast a spell, the Librarian can use its own psychic abilities to try and nullify it. This can be a game-changer in battles where the enemy is heavily reliant on psychic powers.

Lastly, Librarians are also formidable fighters in their own right. They are equipped with a force weapon, which is a type of melee weapon that is able to disrupt enemy energy fields and ignore armor saves. This makes them a serious threat to enemy infantry and characters.

This means that they can effectively soak up damage while other units focus on their objectives.

Moreover, Terminator squads are highly versatile in terms of their weapons and equipment loadout. They can be armed with a variety of weapons, including heavy flamers, assault cannons, thunder hammers, and lightning claws, depending on the mission requirements. This means that regardless of the enemy they face or the terrain they encounter, Terminator squads are always flexible enough to adapt and overcome the situation.

Finally, one of the most significant advantages of Terminator squads is their ability to teleport into a battlezone. This allows them to bypass enemy defenses and quickly establish a foothold in strategic locations. This is especially useful in situations where a quick strike is necessary to turn the tide of a battle.
