The Imperial Fists are one of the most respected Chapters of the Adeptus Astartes. Not only is their loyalty to the Emperor acknowledged as absolute, but their standing with the institutions of the Imperium is unparalleled. Their reputation with the enemies of the Imperium is a greater source of satisfaction to them though.

They have gained battle honours against eight major alien races, been instrumental in holding the Imperium together through the darkest of times, and have the honour of being one of the Chapters to have defended the Imperial Palace in the greatest battle of the Horus Heresy.

COMBAT DOCTRINE
Alongside the Ultramarines, the Imperial Fists have become the epitome of Codex doctrine. All ranks are able to make tactical decisions and are encouraged to act on initiative. The Imperial Fists combine all arms in flexible balanced battle groups, each of which can present an opponent with a diversity of threats, then press their attack so swiftly that the foe is overwhelmed before he can react. They retain their traditional skills in urban and siege warfare, although they are quite willing to engage and defeat the enemy in open battle. They will use fortifications on the defensive, but only after all more aggressive options have been exhausted. Their only weakness is perhaps a reluctance to accept the possibility of defeat that sometimes blinds them to risk.
