There are a multitude of ways a unit can be considered deadly in Warhammer 40k:
High Damage Output: Units that can deal a lot of damage in a single round of shooting or combat are often considered deadly. This can include units with powerful weapons, high strength, or high numbers of attacks.
Resilience: Units that can take a lot of damage and still remain on the battlefield are also considered deadly. This can include units with high toughness, armor saves, or invulnerable saves.
Mobility: Units that can move quickly across the battlefield or have the ability to deep strike can be deadly as they can quickly get into advantageous positions or strike at vulnerable areas of the enemy’s army.
Special Rules: Units that have special rules or abilities that allow them to ignore certain types of damage or provide bonuses to their attacks can also be deadly. Examples of this include units with the “FNP” (Feel No Pain) rule, which allows them to ignore certain wounds, or units with the “Rending” rule, which allows them to deal additional damage on certain rolls.
Synergy: Units that work well together and can support each other’s strengths and weaknesses can be particularly deadly. This includes units that can provide buffs or debuffs to other units, or units that can screen or protect other units from enemy fire.
10) The Dark Eldar Warriors
The Dark Eldar Warriors are a highly mobile and deadly unit. They are fast, durable, and resilient.
The Warriors have a high number of attacks that can be used to quickly destroy their enemies.
9) The Ork Boyz
The Ork Boyz are a unit that relies on numbers. They’re brutally effective in large numbers, unstoppable when they’re all together and cost-effective as well. The Ork Boyz may not be the best melee unit out there, but they do have some useful abilities that make them worth using.
First of all, their Bosspole ability allows them to re-roll failed hit rolls when attacking with a weapon (so long as it’s not an automatic hit). This means that you’ll always get at least one attack off per turn if you use this ability correctly!
Secondly, if any models from this unit die during your opponent’s turn then they come back with 1 wound remaining at the start of your next movement phase
8) The Grey Knight Terminators
The Grey Knight Terminators are a special unit that can be taken as a Heavy Support choice for a Grey Knights army. They are armed with Storm Bolters and Power Weapons, making them great at close combat. They also have Fearless, Relentless and Feel No Pain (6+) which means they will stick around longer than other units.
The downside is that they are expensive points wise at 65 points each but if you have the points to spare then these guys can be worth taking as they will help you get rid of any pesky enemy vehicles or characters in your way!
7) The Chaos Space Marines
Chaos Space Marines are fanatical and fearless, making them an ideal choice for any army looking for a melee unit. They also boast high adaptability, meaning that they can be used in almost any situation.
Their versatility means that they can be deployed in many different ways, making them one of the most versatile units in Warhammer 40k.
6) The Imperial Guard Veterans
The Imperial Guard Veterans are highly trained and equipped. They have access to the best technology, weapons and equipment that the Imperium has to offer. They are unrelenting in their pursuit of victory, and unstoppable when they get there.
The most important aspect of these troops is their survivability; they can take a beating while still being able to dish out damage themselves. This makes them ideal for long drawn out battles where attrition is key – such as against hordes of Orks or Tyranids
5) Eldar Guardains
The Eldar Guardians are a highly mobile and deadly force. They move quickly and can be used in many different situations, making them versatile units that can be deployed in any army list.
Guardians are armed with Shuriken Catapults (24″ S5 AP5 Assault 1) or Pulse Pistols (12″ S4 AP5 Pistol), which means they have good range on their weapons and can deal with enemy infantry as well as light vehicles.
They also have access to some special rules that make them even more deadly; Hit & Run allows them to retreat from combat without suffering any penalties while Fire & Fade gives you bonuses against units that shoot at your Guardians but don’t get into melee with them.
4) Necron Warriors
The Necron Warriors are a resilient and adaptable unit that can be used in many different ways. They come with the ability to take defensive grenades, which can help keep them alive if you need to hold an objective or get out of a tight spot.
Their Gauss Flayer is also not too shabby, as it allows them to strip wounds off of enemy units at range, making them useful against vehicles as well.
3)Space Wolves Grey Hunters
The Grey Hunters are the Space Wolves’ most basic troops, and they are a deadly force to be reckoned with. They have high mobility, making them perfect for flanking units or chasing down fleeing foes.
In addition to their speed, they also have Fearless (meaning they cannot be broken) and Relentless (so they can run and shoot). This means that these guys will not stop until you kill them or make them fall back.
Their main weakness is their lack of AP2 weapons; however, this can be overcome by using large numbers of models in order to overwhelm your opponent’s defenses.
2) The Sisters of Battle Retributors
The Sisters of Battle Retributors are a highly trained and equipped force that can be deployed in any situation. Their versatility makes them useful against all types of enemies, from Orks to Tyranids.
The Sisters’ relentless attacks will not stop until their objective has been achieved or they have been destroyed.
The Retributors are armed with boltguns and flamers, but their real strength comes from their faith in the Emperor; when fighting alongside other units who worship different gods (such as Space Marines), these sisters gain an additional attack dice on every unit within 6″.
1) Blood Angels Sanguinary Guard
The Blood Angels Sanguinary Guard are an elite unit of Space Marines, who are highly revered among the Blood Angels chapter. They are considered to be the finest warriors of the chapter, and they are entrusted with guarding the most valuable relics of their chapter.
The Sanguinary Guard are known for their striking golden armor, adorned with intricate details and wings that symbolize their angelic heritage. They are equipped with a variety of deadly weapons, including power swords and axes, plasma pistols, and inferno pistols.
One of the most notable features of the Sanguinary Guard is their Jump Packs, which allow them to fly over the battlefield and strike their enemies with lightning-fast speed. This makes them highly mobile and effective at quickly responding to threats or flanking enemy positions.
In addition to their impressive combat abilities, the Sanguinary Guard are also highly disciplined and dedicated to their chapter. They are chosen from among the most elite warriors of the Blood Angels, and they undergo rigorous training and testing before being granted the honor of joining the Sanguinary Guard.
Overall, the Blood Angels Sanguinary Guard are a fearsome and highly respected unit in Warhammer 40k. Their combination of deadly weapons, mobility, and unwavering loyalty to their chapter make them a force to be reckoned with on the battlefield.
