Sun Killers

The Sun Killers were the Emperor's Children Legion's veteran Heavy Support Squads, during the Great Crusade and Horus Heresy, that were exclusively armed with heavy Energy Weapons.[1b]
Description
Arrogance is suspected to be the reason behind their eschewing indiscriminate primitive projectile weapons, in favor of more elegant and precise energy weapons. The Sun Killers used these to great effect in war, operated far ahead of their Legion's battle lines, in pursuit of an enemy's largest bioforms or war machines. In doing so, they ensured that they and they alone destroyed such targets, with exacting precision and defined kill shots. In the rare instances that the Emperor's Children opted to make a strategic departure from the field, it fell to the Sun Killers to provide covering fire for their Battle Brothers. They were not compelled to do so by oath or duty, however, but out of boastful pride.[1b]
When they were grouped in squadrons, they were individually referred to as a Sun Killer and were led by officers known as a Novaetor[1b]. The elite of their formation bore the mark of the Sundered Star upon their gilded panoply. These warriors were renowned across the Imperium, due to their Great Crusade exploits, where they had, time and again, sought out and defeated the deadliest Xenos monstrosities and armored behemoths[1a]. Curiously information about Sun Killer squads that failed in their mission, or fell to the enemy, though, are all but unknown. Some believe that all such failures are stricken from the Emperor's Children's records by order of their Primarch Fulgrim himself. In doing so, their was nothing left to tarnish the flawless honor associated with the Sun Killers.[1b]
