Even though the archers managed to kill and wound a lot of Nightmare Creatures, there were still enough of them left to bury the Irregulars under a mass of chitinous bodies. Master Jet's sudden advance divided their attention and lessened the pressure on the rest of the human force, but that was not her primary goal.
In this battle, Soul Reaper was tasked with the most important objective — eliminating the Corrupted abominations that threatened to wipe out the Awakened soldiers.
Awakened were supposed to fight Nightmare Creatures of their own Rank. Facing a Fallen abomination was usually a recipe for disaster, and only a small amount of human warriors could be confident in defeating an overbearing foe like that. Killing a creature of a higher Rank was a rare enough accomplishment that it could substantially change one's reputation.
