Superintendent just finished read the last report of the... Particular incident in the Tiananmen square. The place is now in Military quarantine, not like that place have a people anymore anyway.

"So... General Xi, you do realize that our attention currently is fully focus on Operation Olympus, right?"

"Yes ma'am, i do realize that. That's why i request many of our old weaponry alongside a handful of modern weaponry." Said General Xi.

"I see... General, i give you the permission to this expedition to the Gate... Bring every necessary weapon to that world. Find out about the native, culture and possibly, a new place that we can call Home." Said Superintendent while smiling a bit.

"Understood ma'am!"

Tiananmen square military Base.
18 January, 2050.

General Xi glanced at the sight in front of him. Around two thousand strong soldiers standing proudly, two Battalion of TSF, twenty five old M1A5 Abrams, thirty IFV Lynx, fifteen new ZSU-40-4 and fifty M113 courtesy of the Japanese Marine Corps.

"My fellow Union... Minutes from now, we will step on to the new world, world really unknown to us all. There will be no Satellite or something fancy that we usually use.... But! I know that you people are some tough bastard. My Fellow Union, from now on and forth, we will making history! History for our future offspring! So can live in peace and freedom, and they won't carry our burden and our wound. My fellow Union! March into the Gate and give the Empire from another world some good knocking, Godspeed you magnificent bastard." Said General Xi ending his speech.

"Nice one sir." Comment his Aid.

"Eh, could be better." Xi shrugging his shoulders.

The first line, a group of M1A5 Abrams march forward followed by the TSF Battalions and IFV Lynx.

Walken sighed softly, before drinking one of the energy drink he managed to procure from Taipei. He really want to thank you and shook the madlad that made auto-walk feature in the TSF, really blessing for the pilot when a long arse march like this.

"Hey Mayor! What do you think we gonna see in another side of this Gate?" Asked Hunter-4 curiously.

"Probably problems, a lot of them." Said Walken.

"Yeah, but I'm definitely gonna miss Mama Goose until somehow we managed to made a base." Said Hunter-3 sighing.

"[Glad you people will miss me.]" Mama Goose suddenly said in their comms.

"Ahh! Mama Goose!" Hunter-3 appeared to be surprised by the sudden voice from their Logistic Officer.

"[Why so Suprise, Leo?]" Mama Goose voice sounds amused by Hunter-3 or now known as Leo, suprised sound.

"Nothing, Ma'am! Just saying gonna miss your voice and all." Leo nervously answered.

"Hah! You sound like a child getting caught doing something wrong by your mother." Another woman voice suddenly come in, it's come from Hunter-4 or more known as 2nd Lieutenant Da Qiao.

"Shut Up, Da Qiao!"

"They sound really rowdy like usual, Major." Commented Hunter-5, leader of B Platoon.

Major Walken hummed a bit. "Good, i don't want them to be nervous, how's your teammate? I read from the Documents and reports that you getting the fresh batch from Academy?"

Hunter-5 Sighed a bit. "Yeah, kinda annoying ya know? Now I'm responsible to this little fuckhead, good thing they can still be ordered around and not that pathetic arrogant newbie."

"Then they would never pass the CCSE(1), especially i heard that the Upper echelons say that they would make the already hard CCSE, more harder than before, poor bastard." Say Walken while looking at his HUD.

"Agreed... Hey Hunter-9! Heard that there's some Elf and Neko girl in this world, interested?" Hunter-5 teased the leader of C Platoon.

"Fuck you man."

"Hahahaha!"

"By the way, Sir, why we suddenly changed our Designated name from each platoon? Like, i mean, i don't really mind to use Hunter name, but why so sudden?" Ask Leader of Platoon D, Hunter-13.

"Apparently the Commands said In order to make communication a loteasier, I hope you get used to this in no time." Said Walken squinting his eyes as he saw a dot of light at the end of the dark tunnel.

"Alright, people, we will entering new world in a couple of minutes! We haven't make a rulebook for this world, so, don't become a dumbass and follow the rules like usual. We will be written in history book in the years to come, i hope that all of you will do you duty to the fullest, man... And ladies." Many people in the 66th chuckled at the last part.

"Onwards!" The light becomes really bright and their tanks and IFVs dissapeared from Walken point of view and not long... They too, entering the new world.

..
....

General Phantasa glared at the dozens of enemy iron elephant that are come out from the Gate not just a long ago. He knew they would come sooner or later, but didn't expect this fast. The reinforcement he requested would not come in time for this battle.

"Curse you, otherworlder!"

General Phantasa decided to strike first before their main army arrived and ordered the catapults to launch their boulder. Dozens of catapults flung their boulder toward the Otherworlder Army that are still coming out of the Gate, the catapults aim are quite poor and missed almost all of their shoot by huge margin, couple of the boulders managed to land close to the now Phantasa realize, Iron Golem.

"By Emroy, they managed to tame the Iron Golems?! This will be hard." General Phantasa bit his lip.

"Cavalry, position yourself and attack the enemy from their flanks! Soldiers! March with formation!" His 15.000 or so soldiers with 1.000 Auxiliary monster start to mobilize in short notice, the enemy, however, decided not to give them that luxury.

General Phantasa don't know what happened but suddenly ground around his soldiers start exploding, thunderous thump and destruction rage across his thousands soldier. He see one of the enemy Iron Elephant firing something from it trunk and kill one of the precious Ogre.

"Charge! Don't fear them, for the Emperor!" General Phantasa decided to just, charge the enemy head on.

He didn't know or won't realize that is one of the biggest mistake one leader can make.

...
....

Walken sweated a bit, when the High Command say that they probably gonna engage thousands of enemy, they thought it just another exaggeration for their paranoia, but that's paranoia proof to be true.

"Damn! There's a lot of them!" Irma spraying her Assault Cannon toward the human waves of enemy.

"This is BETA invasion all over again, but god damn, how many are there in this place anyway?!" Hunter-5 cursed as he and couple of his pilot blasting the Enemy Auxiliary monster with 120mm attachment that well.. Attached to their Assault Cannon.

"Zhang-1 said around ten thousands, but knowing all the variables, there's probably more than that." Answer Walken grimly.

"Platoon D and E, go protect our flank, don't make them closer than 900 meters." Walken order them.

"Yes, Sir!" Eight F-35AM TSF moved to their right flank alongside couple of Lynx IFV.

"Platoon C! New target for you, see that Catapults? I don't wanna." Said Walken while continues firing his 36mm Cannon toward the coming enemy with precision and slow tapping, there's no need to go full auto with Assault Cannon against human beings.... It never good and always get nasty.

"Major Walken! Aerial units inbound!" 2nd Lieutenant Da Qiao reported.

"Leo, blast them!" Said Walken toward Leo.

"Roger!" Four Anti-Air missiles launched from two box from Leo's Mech shoulders. Four of the missiles hit the target and four wyverns are down, another missiles from another platoon too are taking down the aerial unit known as The Wyvern.

"Alright people, save your missiles, let the IFV and the SPAAG handle the Aerial unit." Walken says again and true to that, the IFV and the newly arrived ZSU-40-4 begin to shot down every Aerial units that try to do something funny.

"Major Walken, incoming transmission from Colonel Volga, he and the infantry going to arrive in five minutes." Said Irma to him.

"Say to him that by the time they arrived, the enemies already become Red Soup." Said Walken humorously.

"Roger."

Five minutes passed away and Colonel Volga alongside the Infantry arrived in force, the quickly kill or captured the remaining enemies, while the Vanguard forces finally can catch a break for a bit. Major Walken watch from his Mech and realize the amount of bloodshed they've just brought upon this world, monster corpses mangled, horses dying, monster being ripped apart by the Mortar from the Infantry that have just arrive and the most jarring one is the human corpses, Major Walken had a mixing feelings when he see this.

At one side, this people trying to invade their world even though it's failed miserably, and at another side this people have human, the very being that the Union try to protect and preserve, killing them in numbers like this make him feel a bit sick, but his training tough him up.

"Major Walken, all clear, the enemies have been destroyed." Reported Irma while approaching him alongside the rest members of Platoon A.

"Good, All Hunters, regroup on me and standby on order, just got the order from the Command that the 55th Zhao Battalion going to be the first one to conduct recon around the AO, we got a bit R&R while the Army Engineer arrived in couple of days." Said Walken tired.

He see ammo counter in his HUD and suprised that he spend just two Magazine worth of ammunition, probably because the amount of firepower they brought or just the enemies tech tree too damn left behind, either way, Walken just relieve that none of his soldiers are dead.

Superintendent watch closely the report about the battle in another side of the Gate, she had read it for a about, three times already. Surrounding the tables are the High Ranking Officer in Union Army and Important figure for the Union Government.

"Our force win decisively, to the point I'm quite terrified." Commented The Superintendent.

"Yes, Ma'am, it is the truth that Colonel Volga, the current Leader of the Expedition Force, reported to us. No casualties on our side, only couple of unlucky soldiers get nicked by arrow and suprise attack, but nothing that life threatening." Said Brigadier General Xi.

"That sounds really convenient, knowing our enemies are literally still in the middle age." Said Rear Admiral from the South China Sea Region, Fang Zhenya.

"Indeed, Admiral. This report truly are... Eyes opening if you wanna me to say... But that's good, that means we can fully focused on Operation Olympus, the logistics for the war across the Gate gonna be really easy and hard. Easy because we can just yeet the Logistics fleet through the Gate, but the hard gonna be when we... Colonized some of the land there and trying to supply it... If only there's a Gate opening in water body." Everyone in the meeting room agrees and pondered.

Until suddenly Rear Admiral Fang got a notification from her Holopad, she opened it and widened her eyes a bit.

"Uhhh, ma'am, I guess you wishes just being granted, Admiral Johnson from the Far East Fleet just recently found an undiscovered Gate in a Water, the gate is so big that we can fit five Gerald Ford Class Supercarrier in that Gate and still have rooms for couple of escorting ships." Now after that reports, everyone start to murmurs and talk about the possibility.

The Superintendent look really interested and leans her body.

"Can we confirm that this Gate connected to the one in the Beijing?" Ask Superintendent curiously.

"We still yet to know, Admiral Johnson just send two XB-47B to enter the Gate and investigate." Answer Rear Admiral Fang.

"Much interested, what do you people think?" The Superintendent ask the other members in the meeting.

"Madam Superintendent, this is a very good change for us to claim the resources there and use it for the war effort against the BETA, hell, we can just colonized the Entire planet for our own." A High ranking officer representative from the Eastern Europe Region, Lieutenant General Sebastian Vykopal, exclaimed excitedly.

"We shouldn't do that, there's native in that world, we should at least try to befriend with them." Lieutenant General Jayson Miller from the South Africa Region reply with calm voice.

"Baahhh, you Yankees always are cautious in acting, there's a reason why people don't like you." LT. General Sebastian provoked him.

LT. General Jayson just sighed harshly and all American born Officers in the room just avert their faces in annoyance and shame.

The Superintendent then clapped her hands to catch their attention.

"Alright, that's enough of bonding, both of you. For now, we will try the soft way to talk to them and befriend them, but we have to be firm and strong so not to make them underestimate us, i don't want another BETA Invasion on Earth again, or this... Whatever this world are. My Comrades, let's embark onward for a new future!"

Former Imperial Capital Kyoto, Former Empire Of Japan.

First Lieutenant Itami Youji of the Imperial Guard, yawn loudly while rubbing his eyes. He don't get sleep because of watching Anime and reading new Manga, something about Elf Adventure in a fantasy world where the Demon king already defeated.

He see toward the Lake Biwa and he, Itami, never get tired to sea the Imperial Eastern Fleet float gently because of the water. There's there, the legendary ship that have survived more than one hundred years, the glorious IJN Yamato, or more known now as the UNS Yamato.

(I really don't know where to get any picture about fleet in one place, so yeah, gotta love the Man in the High Castle.)

Itami sigh harshly. "Hah... I guess i picked the wrong branch after all, this is suck."

Suddenly, three people with one wearing black blue Imperial Guard uniform and the other two with Red variants, the one wearing black blue grin at Itami, much to his horror.

"Lord Ikaruga, to what pleasure i do for your magnificent presence?" Itami cringed hardly when he said that line.

The one he called Lord Ikaruga grin becomes wider while the other two frowning, know that Itami trying his best to hold the cringe feeling.

"Nothing, Lieutenant Itami, I just simply ask you to become our representative in the Expedition Force to the Gate." Itami blink repeatedly.

"What?"

"Yes, like I said, you will be our representative and you can't denied it. Your skills are going to be needed in this Operation and i want YOU to represent the Empire well and make sure to dig up as much Information as you can." Ikaruga pat his shoulder.

".... Is this the Empress will, or..?"

"The Superintendent-Sama request to the Empress to sent a representative, and with counting every variable, you are the best of the Imperial Guard, now, these two with me had prepare all your needs and daily items, so hurry up and go." Ikaruga make a shooing gesture.

"By yours and the Empress will..."

CCSE or Comprehensive Combat Skill Evaluation (1) : Basically, this exam is for mecha pilot candidates or candidates, here all the skills and training they have learned, be it theory or practice will be evaluated. Sometimes there will be casualties in this evaluation/exam, but with modern standards and medical equipment are getting more advanced, the chance for a pilot candidate to die is already small, the worst is just a disability and usually will be compensated. Basically, like Crucible from USMC.
