With that said I hope you enjoy it and let it be known that while Idon't mind playing Halo I am not that big of a fan of it and don't know the lore all that well so if you see anything that doesn't line up let me know so that i can go and change it.

Well lets try anyways now here you go guys let me know what you think OK.

Chapter 1: Things Have Changed yet are Still the Same

In a lecture hall an ancient picture of how the world was created is projected onto a screen as a man talks "As you may all know it is said that man was created from dust, but we were born into an unforgiving world. A world full of darkness and creatures of destruction, the creatures that were named Grimm and after fighting a battle that man seemed destined to lose we discovered something that would turn the tide of that battle. This discovery was the power of nature itself that became known as Dust. Between Dust, Aura, and our ingenuity we managed to beat back the darkness of the Grimm. Humanity once again flourished into four kingdoms thanks to the continued efforts of the huntsmen, people trained to defend our planet."

Then a man with crazy looking green hair with glasses that cover blue eyes dress in a UNSC Naval officers uniform, with a captain's insignia on it, steps in front of the screen with a remote in hand. He presses a button and the picture changes to a battlefield full of huntsmen, robots, soldiers and weird alien creatures "However around eight years ago a new threat to humanity emerged, but not from the darkness but from the stars." The man presses a button and the screen changes to show many different alien species "We would later find out that this new enemy goes by the name of Covenant. They are a group of aliens that worship technology from a species called the Forerunners and apparently humanity is seen as evil by their religion. So naturally when they discovered Remnant they sought to "cleanse" it so that they may use the planet as an outpost." Then a new picture of a battlefield was projected onto the screen this time showing the forces of Remnant pushing back the Covenant "What they did not expect was that seemingly primitive race would have powers that went beyond their understanding. So for the next seven years we were at war with the Covenant. We even, sadly, had you children fight" he gestures to the children he was currently lecturing. "even though many were against it, but I digress." He then walks over to his desk and picks up his mug of coffee and takes a sip before continuing.

"Now let it be known that while our forces were winning we still suffered loses and many good men, women, children, human and Faunus alike lost their lives in order to protect the world they lived in." the man's face grows sadden as he swirls his cup "Then the Covenant did something that would turn the tide of battle for the worse." The screen changes again to a picture of a virus cell "The Covenant realizing that they would not be able to match our unique technology and abilities without a lot of time decided to take drastic measures. They decided that they would rather make the world uninhabitable than loses a war to some humans. So they infected the world with a virus we now know as The Flood." The screen changes to a photo of a grotesque figure that resembles a human with blades on its arms and clothing that is in shambles "Now normally this is what happens to sentient beings infected by the virus. However, as it turns out our unique ability to control Aura prevents us from becoming that." He points to the screen "However, this immunity came at the price of what made us unique and everyone in the world lost their ability to use Aura and subsequently our Semblances and most Dust, as it required Aura to activate."

He takes another sip of his coffee before continuing "At this time all hope was lost and to make matters worse the Flood virus also had a strange effect on the older Grimm, changing them into something like this." The screen then showed a Beowolf that much like the human before has become grotesque with blades coming out of it that could be fired like a bullet, it also had longer teeth and claws. "Luckily this only happens with some of the older Grimms so they are not all that common, but now humanity was left to fight two wars at the same time without the only thing that was keeping the darkness at bay. The only form of Dust that we are still able to use was when it was in bullet form, but this quickly caused problems as the world was having a hard time adjusting to the sudden change and those who fought without Dust had to adapt, no longer were we able to freely control the forces of nature." Taking the last sip from his mug her walked over to where he had a fresh pot to poor himself another cup. He turns back to his student with fresh coffee in hand "Now Remnant at this point had all but lost hope, but we still tried to struggle to survive hoping that some miracle would appear again to save us from being returned to the void." The screen changed to a photo of a UNSC Cruiser with a fleet of various other UNSC ships "And a miracle we did receive in the form of an extraterrestrial human military. The UNSC appeared from the stars about one year ago and with them they brought new technology that would help us survive the Flood Grimm and Covenant onslaught." The screen changed once again this time to show Spartan armor and various weapons and one girl silently squealed at the sight of such weapons, but the man ignored it and moved on. "This new technology combined with our ingenuity helped us push back our enemies once again giving us some breathing room to help us gather and organize our forces."

With that the projector turned off and the screen started to roll back up into the ceiling as the lights turned back on, much to the most students' displeasure. "This is how where we find ourselves here today. We have now pulled you children off the battlefield in hopes of properly training you with this new technology."

He takes another sip from his already almost empty mug when a girl with long red hair raised her hand. "Professor Oobleck, does this mean that we are no longer to be Huntsmen but rather soldiers?"

Oobleck winces at this question because it was not something he liked very much "First off it is Doctor, I didn't go to school to get this PhD for nothing you know, and to answer your question Miss Nikos." He takes a deep breath to try and calm his anger "I unfortunately have to say yes; we are training you to become soldiers. No longer are there Huntsmen who defend all those that they see or wander the world righting the wrongs of society."

Then another, younger, red headed girl raises her hand "Is the job we are training for really so different because aren't we still here to learn to fight for humanity? It is just a name change right?"

This brings a smile to Oobleck's face "That is an excellent observation Miss Rose and I suppose that you are right, but unlike before you do not have the freedom of choosing where you get to go to help people." Then a bell tolls signaling the end of class "Well that will be all for today. Tomorrow we shall be discussing some of the battles fought in the earlier part of the war and analyze what the commander of the troops did right, wrong and what else he or she could have done for a better victory. Also homework will be an essay on a battle in history with analysis on what could be improved upon and will be due by the end of the week." This earns a bunch of groans from the students "Come now the year has only just begun so know that it will only get harder from here on out and enjoy the easier assignments while you can." With this the man sped out of the class room so fast that it left papers flying out behind him as he went by.

"Man I really need to get my hands on whatever he's got in that mug." Says a girl with blonde haired that goes down a little past her shoulders, much to her disliking, but it was necessary in order to be able to wear the armor, then looks at the younger red headed girl, Ruby Rose, "Hey sis why the glum face."

"I don't want to have to write that essay." She wined to her sister, Yang Xiao Long, as her partner, Weiss Schnee, approached with Blake Belladonna, Yang's partner, with a disapproving look on her face.

"Whether you want to do it or not you have to do it in order to get good enough grades to graduate." Weiss says matter o factly as she crosses her arms in front of her in disapprove.

"I know but…" she continued to wined. Just then Ruby's scroll started to ring and she looked at the message and read it out loud "Would team RWBY please come to Commander Ozpin's office geared up for an urgent mission." She then smiled widely "Oh well doesn't look like we will be able to work on that essay. It is a shame, but what can you do about it." she shrugs the last part. Weiss then promptly smacks her leader in the back of the head which incites a cute wine from Ruby "Oww Weiss why did you hit me?"

"Because you are a dunce who is just trying to get out of doing homework, but be sure as soon as we are back I will make sure that the only things you do are sleep, study, and eat." She turns about to walk to the locker room to change into her armor before she turned her head to look at her partner before saying "And no cookies until the essay is finished."

This cause Ruby to go into a panic "No you can't do that to me! Please have mercy! I swear I'll do the essay just please don't take away the only comfort I have in the world!" Weiss naturally ignored her pleas and continued on to the locker room as Ruby followed wining "WWWeeiiissss come oooooonnnnn!" the remainder of the team just shook their heads and slowly followed.

In Ozpins Office

"Ozpin you aren't serious about sending those children in as their back up." A man with a general's insignia on his shoulder, by the name of James Ironwood, was trying to convince his friend that was just casually sipping coffee from his mug as he looked out the window.

The man he is talking to was none other than Ozpin once head master of Beacon Academy now chief commander of all of Remnant forces. "I am afraid I am serious James." He said as he turned and sat at his desk that was filled with reports from all over Remnant. While he did not want it he was placed as the head of all military action on Remnant by the UNSC because he had more experience that even they did not have.

"Ozpin, listen I trust that you think that you are making the right decision here, but please try to reconsider in sending a more experienced team." Ironwood pleaded trying to help his friend see reason.

"Are you saying that the team he picked isn't capable?" said a woman holding a tablet with her hair up in a bun also with a general's insignia.

"No Glynda I'm not, but I believe that this may be too much for them to handle and think it would be a good idea to send some more experienced soldiers with them."

"Oh if that is all you wanted it has already been taken care of." Ozpin said as he casually sips his coffee while going over some report about a resent Op against a covenant outpost. He could only sigh as they are heavily entrenched and that it will be taking more effort on their part if they wanted to do this without taking to many casualties.

"Who are you going to be sending with them?"

Ozpin nodded to Glynda who, after a few swipes on her tablet, handed Ironwood her tablet that had a picture of four boys on it. "These four have already been dispatched and will be there shortly before team RWBY who will be providing backup for them."

Ironwood looks over their profiles for a few seconds before he notices something "Ozpin these are the people that the UNSC is sending to track our progress in the training of Spartan soldiers! How can you put them in danger like this! If these kids die on our watch than our relationship with the UNSC will be put into jeopardy with a good chance that you will be taken out of your position with one their lapdogs to replace you!" he slams down the tablet onto the desk to emphasize his point, which earned him glare from Glynda, as he continues "Not only that, but they are still children probably fresh out of their academy not trained and seasoned warriors that I want to send with team RWBY!" he wasn't usually this emotional about one of Ozpin's decisions, but these four were some of the best students they had since the start of training Spartans instead of Huntsmen and he didn't want to lose them that easily.

Ozpin sighed before he looked up at Ironwood with a rare serious face that made him back up a little "I am aware of what I am doing her James and there is no need for concern. Experience wise the four that the UNSC sent us, while they are young, have more experience than every student that we are currently teaching." Calming himself a bit he takes a sip from his coffee that is now almost empty. "Besides if they are going to be participating here as students they are going to have to go through initiation and our usual methods won't work so this will be a good place to test them."

Ironwood sighs in defeat as he turns to leave "Fine Ozpin you are the Commander after all, but let it be known that I tried to stop you before anything goes wrong."

As he opens the doors to the office he almost runs into none other team RWBY themselves "Oh sorry General Ironwood." Says the team leader as they all step aside and each giving a slightly different salute.

Ironwood sighs as he walks past them "At ease girls." He says as he gives their equipment a good once over.

Their leader, Ruby Rose, had the now standard Spartan armor that is mostly red with black accents, but as most people of Remnant tended to do she heavily modified it. the armor now had little jet burners in various places on the armor in a way that he assumed would give extra speed and mobility to the user, but most others would not be able to use it effectively like Miss Rose can. On her back was a sniper rifle that would have seemed too large for her if it wasn't for the fact that she modified it as well. Now her rifle was able to change into not only the standard rifle, but she also managed to find a way for it to change into something called a Binary Rifle that can incinerate any organic organism, but can only be fired a few times. Also it has an attachment area for an energy based bayonet to be used in close quarters combat. On her hip was an unmodified Magnum that she left as "classic as possible" as she likes to put it, but was still capable of using Dust rounds. Finally, she had standard plasma grenades provided by the UNSC that we have been able to replicate. She smiled faintly as she lowered her rather hasty salute and next to her was her partner Weiss Schnee.

The Heiress to one of the companies that was hit the hardest with the almost complete drop in Dust's value, until they started signing contracts with the UNSC to make experimental ammo, armor and other technology using dust. She was geared with white and red accented armor that has been modified to look elegant, not that it would help her combat wise, and had several hidden functions that he has only read about in reports. Apparently the armor has some form of tracking system that is based off of the experimental UNSC ATS (Artemis Tracking System) that allows her to spot enemy weaknesses that her team can exploit. Also she is able to place a recuperative energy field as well as a bubble shield. On her back was a standard looking DMR, but after reading some reports he knew that it could also shift into a Railgun and almost all her rounds were special Dust rounds. On her waist was her secondary weapon a plasma pistol that could mecha shift into an energy sword that would remind people of a rapier if you saw it. Lastly, she had various colored grenades that he assumes is filled with Dust. She had a more professional salute most likely from her years up in Atlas.

Then there was the Faunus member of the group Blake Belladonna, who he was always suspicious about, but Ozpin insists that there is nothing to worry about so he never looked too deep into the matter. She was geared with a mostly black and white armor that can make holographic copies of herself that can move around to distract enemies, get her out of bad situations, and she can even have them specially charged with Dust for different effects she also has magnetic grips on the bottom of her feet so that she can move around and always have secure footing even on walls and ceilings. On her back she has a standard Assault rifle that she normally uses lightning Dust when she isn't using regular bullets. Then on her waist was a pair of plasma rifles that she dual wielded and modified that each was able to shift into energy blades. As for her explosive choice she has a mix of regular and Dust filled Fragmentation grenades. Her salute is standard nothing really sticking out except that she didn't seem to want to meet his eyes and while he knew that he was a pretty intimidating man this did not help with his suspicions of the girl, but since a year has passed with no negative incidents he chose to ignore it.

Finally, there was the blonde brawler and half-sister to their leader Yang Xiao Long, that he heard when it was time to cut everyone's hair to length so that they could fit in the helmet she had to be held down while they cut it and then after they were done she knocked out the barber and several of his soldiers before she calmed down. She had an armor that was a mix of yellow and black that all of the modifications went toward increasing her strength and while she wasn't as fast as her team mates she was leagues stronger than they were. Also she modified the arm pieces to have six inch spikes come out when she punched something making her one of the most capable hand to hand combatants in the school. On her back was a Fuel Rod Cannon that has been modified to shoot Rods that can be filled with fire and lightning Dust and it can mecha shift into weapon that is known as a Spartan laser that uses the fuel rods as the energy source. Her secondary weapon is a shotgun with a special modification that has a part of the gun detach that shifts to form a Bolt shot. Even though her main gun is explosive based she also carries around her own mix of grenades from the same types as her teammates. Her salute is far more casual than anyone he has ever seen and while Ironwood thinks that she is far too casual he wouldn't want to force her to change to become someone she is not.

"So what were you and commander Ozpin discussing?" Yang asks out of curiosity.

"We were discussing an operation." He then continues on his way to the elevator "And shouldn't you be reporting for your mission instead of standing around here asking me questions?"

Yang laughs nervously as she and the rest of the team enter the office. "Welcome girls and how are you today?" Ozpin asks in his usual friendly tone

They all stand at attention as Weiss speaks "With all due respect sir can we please skip the formalities. We have an essay that needs to be done right after this mission is over." This cause Ruby to groan.

Ozpin chuckles before he gets a serious look on his face "Very well I will get straight to the point." He pulls out four files and hands them to Glynda who walks over to team RWBY and passes the folders to each of them. "You are to provide reinforcement to the town listed in the file. It is currently under siege by a mix of regular Grimm and small Covenant raiding parties and while they are holding off the enemy they need your assistance. So you are going to meet up with another team at the location, at such a time the leader of the other team will be in charge of the operation and you are to stop both the raids and the Grimm attacks."

As he explains the mission each member is looking through the files and they almost all stop on the same page at the same time as Ruby speaks up "Is this really the town that is under siege?" her voice is calm as she asks, but her body is visibly shaking.

"Unfortunately it is."

At this Ruby speeds out of the office while shouting "We will be leaving immediately and be there with in the next few hours!" the rest of her team rushes out to follow and Weiss gives a quick apology for her leader's behavior.

"Ozpin are you sure about this? Won't their emotions be running too high to be able to make the right decisions?" Glynda asks worried not only about the students but also the people of the town.

"Of course that is why the new team is in charge of the OP." he replies calmly as he gets up to refill his mug.

"Still it may be traumatizing, after all that is the place where they grew up."

"And that is precisely why I picked them because no one else in this school will know Patch better than them." Ozpin says as he takes a long sip from his mug as he looks out of his window hoping, praying that this will not be added onto his long list of bad decisions.

On the main UNSC Cruiser

"Aw man the first time we can get out of this stuffy ship and down onto this new planet and it is basically just us going back to the academy, what a drag!" complains a Spartan in black armor with purple accents.

"Quit your complaining you are only going to make this mission more unbearable with your useless complaints." Snaps the Spartan next to him that has grey armor with white as the secondary color.

"Come on guys neither of you are helping this situation and besides I am sure that both of you will be able to be prom queen if you share." Says the Spartan with a dark blue armor that has dark red accents leading the group.

Next to him was a Spartan with dark brown armor with lighter brown accents. This Spartan remained silent as the rest of his team bickered over what he found to be a useless topic.

As they enter the hanger there is a pilot waiting for them "I am sorry Sirs, but there appears to be a change in plan." She says as pulls out a tablet with the new orders "Apparently there is a town under siege and they want you to provide back up for the team that has already been dispatched."

She hands the tablet over to the leader who sighs "So is the Pelican up and running yet."

"Yep already to go!" she replies gleefully "Just make sure your AIs stay out of my ships computer

He gives her a nod of agreement "Ok then everyone let's get on and get this over with." He says as he and the rest of the team board the ship.

"WOOOOOO! Yes! Some action!" shouted the black and purple armor one.

The leader sighs "I just hope things won't be too bad before we get there." Then as soon as everyone has boarded the ship closes and they set off for Remnant to assist in the defence of a little island town called Patch.

And done man it is a drag to have to do all of that research just so that i make sure that i do the lore of Halo justice anyways I have something to ask I am looking for some help with this and other stories.

What i need is a Beta reader for this story and some ideas latter on for chapters.

Also i need OCs and OC RWBY teams for my other stories and if you guys haven't yet check out my other story i am writing that is a Bleach x RWBY crossover that i think is going quite well actually.

Anyways ill be back with another chapter eventually it depends on which Muse gets to me first later.
