Death in the Mountains
D'leh, Scout Marine of the Celestial Lions, knelt atop a mountain, his camo-cloak concealing him from view even with the brilliance of his golden amour.
"Grant me the sight of the eagle, the calm of the breeze, the patience of a saint and the skill to smite the foe from afar." the young man prayed, his rifle butt against the stone, fist over his heart.
"Make ready." came the order from Sergeant Sido, the veteran recovered from the injuries he took in the jungle, his back and torso now mostly bionics, whirling gently as he moved.
D'leh stood, going to his perch above the horde of mutants below.
The group had been identified by the previous aerial reconnaissance and pict-files taken by the 10th Company years before, several thousand daemon worshippers camped in crude dwellings in a mountain valley in the west of Araby, frequently raiding passes and the coastal cities of that area. After due consideration the Chapter Master had ordered their destruction, and D'leh was proud his squad had been chosen to deliver the Emperor's judgement.
Since the year in the jungle the Scout had found his faith renewed. He'd taken Sido's words to heart, setting himself to his tasks with diligence that his trainers had commended. He was the finest Scout in the 10th Company, and soon he would complete his training and become in truth a Battle-Brother.
D'leh looked down at the writhing mass below him. They were high up, a thousand metres or more above the horde, yet even without his rifle's scope he could see the disgusting variation in the physicality of the creatures below. While some might have passed as humans once, others were scaled and furred, great horns and frills growing from their heads, some with manes or clawed hands, the mocking union of beast and man.
"I have the target, Brother-Sergeant." D'leh reported, the fiery runes on his rifle's scope centred over a large mutant's horned head.
The catechisms of worship were spoken, the Scout's wargear sanctified, the craft of death elevated to a blinding focus in his mind. The others of the squad made the final checks to their own weapons, incense and iron, blood and the Emperor.
The words came unconsciously to D'leh's mind, his faith, notable among his brothers, giving him strength. While most Space Marines viewed the Emperor as an exceptional man and inspiration, rather than a god to be worshipped, the Celestial Lions' Chapter Cult was flexible enough that D'leh's memories of his childhood had been exempt from the ordinary mind-scrub protocols. Turning his thoughts to the task, he spoke the Chant of Accuracy, "God-Emperor! Guide the flight, watch the target, take the unworthy's life!"
"Good initiative D'leh." Sido said quietly beside him, evidently having heard his prayer even without it being broadcast through the helmet's speakers. "All Scouts, vox-casters to maximum, recite the Prayer of Hatred with each shot. I shall lead your volleys."
Acknowledgements by vox came swiftly in from the nine other Scouts dotted around the escarpment.
"To be Unclean." Sido's voice boomed.
The beast-witch in D'leh's scope ceased it's chanting, knife raised over a sacrifice to its dark masters.
Then the creature's head exploded.
"That is the mark of the Mutant!" The Scouts roared, their voices magnified a hundred-fold, lashing the enemy with waves of sound as more of them died.
"To be Impure." Sido intoned.
"That is the mark of the Mutant!" The Scouts repeated.
D'leh guided his shots to the Beastmen leaders, picking one off at a time.
"To be Abhorred." the Sergeant's voice rumbled through the mountains.
"That is the mark of the Mutant!" came the chant again, Scout Arif letting loose with his Heavy Bolter, a thousand rounds a minute cutting swathes through the packed masses of the mutants.
"To be Reviled." the shout went.
"That is the mark of the Mutant!" and D'leh saw pebbles shaking at the vox blasts, the mutant horde below utterly panicked.
"To be Hunted." Sido's auspex picked out priority targets for them as he spoke.
"That is the fate of the Mutant!" ten voices as one, sweeping their foes away.
"To be Purged." a rocket screamed down, the frak warhead busting apart, shredding one enormous bovine creature with four blade bearing arms.
"That is the fate of the Mutant!" D'leh's hearts thundered as he fired, walking his shots through the masses of Beastmen trying to escape the deathdealers, sending them fleeing back toward their foul settlement.
"To be Cleansed." More fled, yet the forests on the mountains' slopes were no match for the bolter rounds of the Scouts' weapons and D'leh's auspex picked one out, huddled behind a tree, his mutated skeleton clear even through the tree as the advanced sensors identified him.
"That is the fate of the Mutant!" The round took the hiding creature, blasting the tree in half, the splinters flying into those around the beast.
There was a moment's calm, the bolters fell silent, the heavy weapon operators changing the belts and magazines of their implements.
The Chant had concluded, yet their enemy still lived.
Sido observed the carnage, the Beastmen fighting each other as they tried to escape the invisible death. "They know fear." the Sergeant remarked, his voice cold, "Let them know terror. Mark your targets and fire on your own initiative. By the Emperor, show them no mercy."
