Warhammer Space Marine Chapter character traits:

The World Eaters and the Daemons of Khorne.

I like close combat. During the Great Crusade, I was good at airborne landings and melee assaults. This was also the case after joining Khorne. I used a chain saw ax in one hand and a blaster pistol in the other to rush up. I despised long-range and psychic abilities.

Iron Warriors.

Big bomb, no matter what the opponent is, take a round of artillery strikes from me before talking, never lack ammunition, pursue extreme fire suppression, the original body Pitrabo is as talented as Leonardo da Vinci, but He has been used as a gunman, and his dream is to build a rational utopia. He is a rare scientist in 40k. His combat style is fire suppression and precise control. He is a real-life RTS player.

Dark Angel.

My favorite unit, this is the template for all SM, the earliest Death Angel, with a versatile tactical style and a variety of experimental weapons. To quickly attack the army, there are Raven Wings, heavy armored elites and Death Wings, in short, they are the template for all SM, whether it is quantity, tactics, or anything else, they are impeccable.

Grey Knight.

Anti-demon professionals are formed by loyalists from the rebel legion. All equipment and tactics are prepared for demons. They are extremely loyal and have no record of rebellion.

Extra story:

The transformation process of Imperial Fist recruits is extremely painful. The recruits are required to stay awake during the operation and endure the severe pain. It is difficult to say whether this is caused by the gene seeds or the Empire. The Imperial Fists would introduce a sense of ritual in the future, but one of the legionary cultures of the Imperial Fists is taking pride in enduring pain. Almost all warriors will deliberately inflict pain on themselves to develop their tolerance for physical pain.

So the Imperial Fists invented a special item called the Gauntlet of Pain, which can cause severe pain without causing actual trauma. Warriors of the Imperial Fists often wear this torture device to temper their will, competing to see who can last the longest and who can endure the most pain.
