At exactly 0500 hours planet-side the supercomputer in the planetary defense headquarters hummed to life, it's sensors picking up the long-awaited sign of the arriving invaders. The military junta of Aatov had filled it's airwaves with propaganda, spurring the militant populace against the new alien menace, which had contested it's 'rightful' claims on a mineral rich asteroid belt in a nearby system.
What the planetary media hadn't reported was the catastrophic losses that the Aatovian navy had suffered in the belt, and the sudden but total communications silence that the home world had experienced with its outer stations and several colonies.
As dawn arrived on the most densely populated and defended hemisphere of the planet the computer controlled defense arrays suddenly spurred into motion, and klaxon alarms began to wail across the countless barracks and bastions that spread across the continent.
Before the spotters and ground radars could even make out any targets the anti-naval missiles shrieked out of their silos, sailing upwards into the atmosphere until they passed out of sight. The infantry watched expectantly for the first distant flashes of atomic bursts but as the seconds passed without effect tension grew.
Then the pale blue of the sky became faintly blurred with the indistinct shapes of approaching objects- massive ones at that; growing larger at a rate greater than any landing ship.
"Divisions; fire all anti-air weaponry! For Aatov!" crackled the loudspeakers across dozens of city-fortresses.
Countless auto-cannons and heavy guns roared to life, throwing thousands of flak shells skywards hoping to intercept any approaching landing ships.
Then with a shocking alacrity, the shapeless approaching forms took on very distinct silhouettes as they brushed the atmosphere and briefly became radiant with the golden aura of re-entry.
The defense supercomputer received the first radar reports on the targets as they dropped rapidly towards the surface. It's algorithms first classified them as capital-class battleships set on a suicide burn or unintentional warp glide towards the surface and put Aatovian odds of victory at 100%.
Then as these colossal bodies seemed to slow and group themselves into a landing formation with a deftness completely impossible for spacecraft of their size it re-evaluated them as rocket-steered anti-planetary weapons and accounted for impact casualties, factoring overall chances of victory at 99.999%.
Finally the objects entered visual range as they passed through the stratosphere and the defense supercomputer promptly crashed as its strategic processors impossibly spiked the odds of victory to a negative integer.
Just after the deafening boom of re-entry the defenders of the bastions heard a faint sound rising in volume until it became a distinct battle-cry which overwhelmed even the thundering of the automated defenses.
"NYAAAAAAAAAAAAAA~!"
A massive blast of hot wind buffeted the defenders, tearing power cables off of their poles and throwing soldiers to the ground. The loud hiss of thrusters sounded before a dozen loud crunches marked the landing of unfathomably huge boots on top of hundreds of defenders and their fortresses.
"Nya! Get some you ugly sons of-" A bubbly voice belted in its best attempt at a war cry before cutting short. "
Uh, Sarge I don't see anyone." the voice muttered disappointedly.
Standing in a rough circle with weapons trained on the horizon, stood seven colossal beings. They were human-like with the only marked difference being a pair of cat ears atop each of their heads and long slender tails swashing back and forth aggressively behind them.
As the defenders not flattened by their impact returned to their feet and looked skyward they were greeted by a panorama of panty clad females visible from below; their thighs and rears in various states of thickness and musculature. The immediate bemusement of their view was overtaken quickly by the dread of realization that these figures stood miles in height, towering over the defenses and cities of the planet like immense living capital ships.
The catgirls were all clad in military uniforms; namely tunics and skirts of an gray drab color. The foremost among them was wearing a peaked cap atop her head, while the others wore a mix of garrison caps and steel helmets. The equipment the Aatovian defenders were naturally most aware of were of course their black high boots, which stretched above their heads like skyscrapers in and of themselves.
The soles alone were over 150 feet thick and had sunk deep into the mud that had been made of the land beneath their unfathomable weight.
"Hmm- Brass said this continent had the most staunch defenses. Damn it- we must be outta' position. Give me the map TL." A more gruff woman's voice sounded.
"Uh- yes ma'am. Just a sec." Another replied coolly.
With a sudden crash a skyscraper sized rifle-butt landed atop a series of hill-top bunkers, utterly obliterating them, seemingly without being noticed by the immense soldier above.
A deafening ruffling of paper sounded as the Team Leader drew a map from one of her vest pockets and handed it to her impatient Sergeant, who snatched it up and mulled it over.
Beneath this exchange the Aatovian soldiers milled uncertainly, some clinging to their gun mounts, others edging closer to bolting for the entrances to the extensive underground defenses beneath them. Finally after what felt like hours without so much as a word spoken the loudspeakers across the area crackled to life as the voice of a moral officer shakily sounded.
"Uh- B-brave soldiers of Aatov! The invaders are but mere young girls before us, and beastly ones at that! Let loose the t-thunder of Aatovian steel!" The voice cried, sounding only half convinced of its own verve.
After a moment of nervous trepidation the most steeled Aatovian defenders rushed back to man their weapons and began to fire skyward, mostly at the only thing they could see- the undersides of the miles-tall catgirls' skirts.
"Nya~! What was that?" One of the anti-tank gun armed girls cried, dropping her sizeable rifle and clutching at her skirt.
"We under fire?" The largest among them cried, waving her machine gun down range at the seemingly flat horizon.
One of the soldiers straightened her glasses and looked at the ground. "It doesn't seem like real fire- some kind of diversion?" She conjectured.
"Huh? Wait- look." The Team Leader replied, squatting low and pushing her goggles onto the rim of her peaked cap.
"S-Sarge, I-I think I spotted the hostiles." She chucked incredulously, watching as tiny puffs of flak burst well below her face.
"Gray what are you on about?" The Squad Leader asked impatiently, still pouring over the planetary map.
The Team Leader, Gray, was the most veteran of the squad; made evident by the number of pins mounted on her chest and the slight crow's-feet starting to form at the corner of her almond shaped eyes. Her skin was a dark tan and her short cropped silver hair lent her the moniker 'Gray'. A slender but comely dueling scar ran across her left eye, making their bright crimson color all the more striking.
She turned over a toothpick in her mouth as she tentatively poked a finger at a pea-sized concrete fortification, drawing it back quickly as it effortlessly flattened it into a patch of rubble.
The Aatovian soldiers beneath her squatting form could tell that even in comparison to the monolithic bodies of the other invaders she was quite bottom heavy; her muscular thighs holding up a plush butt barely wrapped in standard-issue white panties.
"This is a Class C world right? A super-dense planet?" She inquired, her voice mature but not as harsh as her Squad Leader's.
"You weren't paying attention in briefing were you Gray? Of course it is- that's why they had us in high-gravity conditioning on the way here." She replied tersely.
Gray's ears perked up and she nodded understandingly.
"I've heard about this from some other vets. Every now and then on these high-grav worlds some intelligent life manages to evolve despite the pressure, but they come out super-tiny like. They can fit tons of them on a world too compared to us." Gray commented, idly popping another concrete redoubt under her pinky.
"So they sent us all the way out here just to step on some mites is what you're saying? Goddamnit I shoulda' known this was a fluff assignment when they didn't even equip us with heavy armor." She muttered angrily, crumpling her map into a massive ball and tossing it in frustration to the ground, where it promptly crushed several acres of farmland.
"Still- they must be some kinda' threat if HQ didn't just ignore em'- what was it, 'Avonia', 'Aatovia'- from the get go? Usually when they find a race like this the little things try as quick as possible to sign a peace treaty and be our friends. Besides, we can't just go back to base and say 'we thought the mission was stupid so we had a picnic and came back for supper', can we Sarge?" Gray replied deadpan.
Sarge gritted her teeth and removed her peaked cap, brushing some sweat from her brow and running it through her feathery burgundy hair.
"Fine. Our landing objectives were supposed to be to secure the spaceport to the east, and to disable the continental citadel to the south-west. Gray, you take Nyamato and Mimi and take care of the airfield. I'll take Jin, Lin, and Nyaomi and see what these bugs pass for a 'citadel'.
Sarge pulled a three pronged apparatus from a satchel on her belt and extended each prong with the press of a button, before contemptuously dropping it to the ground.
"Help me 'clear' this LZ, if we're going to take this seriously." Sarge ordered, looking down at the landscape arrayed below her. She suddenly removed her backpack and dropped it deliberately on a large fortress before proceeding to harshly kick at any other defenses she could reach, clearly venting her irritation upon the miniscule hostile forces still plinking away at her with ineffective fire.
"Don't want these 'soldiers' crawling into my kit!" She grunted half-sarcastically.
Within mere seconds she had managed to completely decimate an entire division of artillery- rocket pods, cannons, and observation posts becoming twisted debris stuck in the ridges of her boot sole.
The other girls promptly did the same, dropping their kits in a circle and taking to probing at the resilience of the Aatovian landscape with varying degrees of excitement.
Jin and Lin, the two weapon specialists Sarge had claimed for her team were a pair of twins- both sporting similar good looks and overall thick proportions; a relatively even mix of fitness, curviness, and voluptuousness. They shared straight blond hair, arranged into long ponytails and tied with black ribbon. The only outward difference was the nature of their shared heterochromia- Jin's left eye was blue and her right was green, while Lin's was the opposite.
Subtleties aside, the two girls certainly took to their orders to clear the LZ with equal zeal- giggling amongst themselves as they cast off their heavy support equipment and took to stomping at the crunchy landscape.
Nyaomi was the squad's medic, and appeared to be the least enthusiastic amongst the girls. Her physique was somewhat plump, while still demonstrating some underlying muscle as she effortlessly unslung her medical supplies and gently set them down.
She possessed soft, but attractive looks and her face was defined by a pair of thin-framed circular glasses and framed by a luscious volume of black hair that spilled over her shoulders. Her ears twitched acutely as she listened to the unintelligible squeaking of the loudspeakers below- curious to what they could possibly be saying to compel the mite-sized soldiers below to continue their fire upon her squad.
Regardless of her curiosity she took to deliberately stepping on anything that looked like fortifications, her steel toed boot sinking softly into the rapidly flooding fields that the girls collective weight had began to drop into the water table.
"Good thing our kits are waterproof I guess." She muttered, holding her curled hand to her chin.
Gray took to the demolition of her assigned defenses with her usual stoicism, her expression betraying the slightest bit of diffidence towards crushing such a seemingly harmless enemy- but the continued and intensifying artillery fire that burst around her thighs and knees demonstrated how militarized these Aatovians were. Any sensible race this small would have tried to surrender by now she thought. Her thoughts turned to her squad and she did a quick head-count to see how the others assigned to her were handling things.
The largest of the squad, Nyamato was evidently quite amused with the circumstances, as she had hastily thrown down her belts of ammunition and machinegun and taken to firmly and deliberately stomping anything even remotely threatening looking under her immense boots.
A toothy grin of unbridled amusement spread across her strong jaw, and her short shorn blonde hair was already glistening with sweat. There was a certain menacing glint in her golden eyes, but Gray chalked it up to the adrenaline of the landing.
Nyamato was a beast of a girl- a solid head and a half taller than even Sarge and built like a brick shit house. Her shoulders and core were thick enough around that her belts had to be tailored to fit, and her tunic clung tightly to her defined musculature and sizeable breasts. Her legs were like thick columns emerging from her skirt- tensing and releasing with each thump of her footfalls and subsequent twists and scrapes of her boots through the disintegrating trench lines beneath them. Even her fluffy white-tipped ears seemed more muscular and larger than the rest of the squads, and they twitched with each explosion of a fuel or ammo dump that she annihilated.
The final and youngest of the squad was currently leaping up and down with her hands clinging to the straps of her pack like a kid hopping in a puddle. Mimi, the squad Anti-Tank specialist only stood as tall as most of the others' chests, but her own chest was almost absurdly oversized for her frame. Substantial enough that in assignment she had been selected for her skill with an anti-tank rifle, a weapon that any less endowed girl of her height would have been sent flying by the recoil of.
Her youthful face was illuminated with a massive smile as she carelessly shed the last of her heavy kit and stomped with both feet atop a concrete redoubt the size of a small stadium, her immense breasts jiggling under her uniform.
When the first several 'meters' around the LZ had finally been pounded into several square miles of squashed mud and shattered concrete, Sarge let out a huff and signaled for the others to stop.
"Regroup at the beacon at 1900 hours, or whenever you get bored of having come all this way to not see any real action." She barked bitterly, gesturing to the twin weapon specialists and the medic and starting to walk to the south, indifferent to the artillery fire harmlessly bursting on her boots and legs.
"Cya' girls- have fun!" Jin and Lin chimed in at the same time- trotting off after their Sergeant hand in hand.
"Try not to get hurt while I'm not there- I guess... don't trip, or drink any water you don't know is clean!" Nyaomi added, taking her place at the rear of the column.
"Alright- let's get going then." Gray ordered, casually crossing her hands behind her head and starting slowly towards the East. Nyamato and Mimi looked to each other and noticed their shared grins, laughing as the larger of the two picked up the smaller and sat her atop her shoulders, letting Mimi rest her breasts softly atop Nyamato's garrison cap.
"Cakewalk!" Mimi chimed, Nyamato echoing her as she stomped off heavily behind Gray.
