A/N: Ok, so this is probably going to be my first story that I've ever written in my life. Some ideas came out of my head for this one, some didn't. With that said, I would like to give credit where credit is due. This story is inspired from loveable-elsanna's "Operation GingerAil." Anyways, this story is a crossover between Frozen and the campaigns of Battlefield 3 and 4. Some additional information to know in this AU: Vladimir and Kiril survive the nuclear explosion in Paris, Dima survives the fall from the mountain (more on this later), all of Tombstone Squad at the end of the Battlefield 4 campaign mission of Suez survive (Irish, Recker, Hannah, and Pac), as well as the Valkyrie and its crew. Be sure to leave a review, and enjoy!

"Hey Reck, wake up."

"Mmmughh...Irish...what is it?"

"Get up, it's important. Garrison wants us topside in ten mikes."

As the hazy blur of waking up from a long nap came into focus, Sergeant Daniel Recker turned to see his squadmate, Sergeant Kimble Graves, better known as Irish, standing next to his bed. An urge creeped into Recker to punch Irish and roll over to go back to sleep, but he resisted. He'd seen too much violence in his life, and who knows what Captain Garrison wanted.

"How important?" Recker's voice ached with lethargy.

"Top-secret important. Now get up, I'll meet you in the briefing room with the rest of Tombstone." And with that, Irish exited the small tin can of a 6-bed cabin Recker was assigned to.

Shit, I hope I don't have to experience anything that will get me killed, Recker thought to himself as he hopped off the bed he was laying on. He didn't have to change clothes or anything, as he had been sleeping in his combat uniform. As Recker walked toward the briefing room, he recollected what happened on his last mission that occurred six months ago, and that had almost gotten him killed. While pursuing Chinese Admiral Chang in the Suez Canal, the USS Valkyrie almost got destroyed, but was saved last minute when Recker, Irish, and a Chinese intelligence agent named Hannah had driven a RHIB boat right to the side of a Chinese warship where Admiral Chang was overseeing the attack on the Valkyrie. They had planted a C4 charge on the side of the warship, and had grappled their way up to a bridge above the colossal ship. Only then did they found out the charge was a dud, and one of them had to drop back down to set a new one. Irish and Hannah bickered over which one of them would go down, but Recker had volunteered to go down. After much protest from Irish, Recker unhooked himself and dropped back down to reset the charge. After giving the signal that it was set, Recker swam as fast as he could before the charge was detonated. Unfortunately, when the charge exploded, Recker was a hit by a piece of debris and was knocked unconscious. Several hours later, he found to his surprise he was in the med bay of the Valkyrie, alive and well.

If Irish went down there himself, he probably would've said, "No fucking regrets." Me? Well, I guess that's what I signed up for. Recker was well aware of the risks of a Marine, but since the War of 2020 was over, he was curious to see what Garrison had requested him for.

Finally reaching the briefing room, Recker took a huge breath and opened the door. He saw Captain Garrison and Irish, but was surprised to see Sergeant Clayton "Pac" Pakowski and Hannah. They were all in full combat gear (so was Recker) and turned to see Recker enter the room.

"Captain Garrison, Sergeant Recker reporting in. What d'ya need me for?

"Come on over here, I'll brief you."

As soon as Recker joined the rest of Tombstone Squad, as well as Recker giving a couple of nods of greeting to Hannah and Pac, Garrison began to brief them.

"So, you all are probably wondering why I requested all four of you here. Well, let me explain."

Garrison pulled something up on a computer sitting on the table in front of him and projected it onto a screen behind him. What he showed were two men and a map of Europe.

"I'm sure you all know about the two largest oil companies in the world right now. If you don't, well let me brief on it. Here on the left, we have a man named Edgar Nicholson, CEO of Nicholson International, a large United States oil company that primarily profits the US, and many of the oil fields that he has under his control span across the globe, including Europe. The other picture shows Anatoly Voronkov, CEO of Medved Neftegazovyy, a Russian-based oil company much larger than Nicholson, and they also have oilfields across the world. See where I'm going with this?"

Irish responded, "No sir, what are you implying?"

Garrison continued, "Recently, there have been conflicts between the two companies. Nicholson has been forcing Medved to sell them their oilfields near Russia, especially in the Caucasus region. However, Nicholson has been facing financial difficulties, but is slowly recovering. Early intelligence on the situation shows Voronkov wants all of the European oilfields that Nicholson owns, and is willing to go to extremes to get that accomplished. This is where the financial difficulty problem comes in. Since they're having money problems, we believe that they won't be able to afford security personnel to protect their oilfields and offices. One of the most vulnerable locations is their headquarters in Paris, where Medved also happens to be headquartered. Let me pull up some SAT images."

As Garrison pulled up some images on the screen behind him, Recker thought as to where this was leading to. Hopefully, nothing too dangerous.

Finally loading the images on-screen, Garrison turned behind to show Tombstone what he was talking about.

The image was of a large avenue in Paris, but the focus was on a large building at an intersection on the avenue.

"This here is the headquarters of Nicholson International." And pulling up another image, Garrison said, "and here is the headquarters of Medved, literally blocks down the street from where Nicholson is stationed. What we think is what's happening is that Medved might be hiring militants and spec ops agents to spy and attack the Nicholson HQ. If you look closely here," Garrison pointed to a few dots in front of the building, "these are probable hired mercenaries, but we believe they are Russian spec ops as security detail."

Pac chimed in, "So, what's our mission?"

Garrison responded, "Your mission, is to protect Mr. Nicholson and his family, who also live in Paris not too far from the headquarters. If necessary, perform some recon on Medved and provide intelligence to me, which I'll relay to JSOC and the CIA. On that note, the CIA has managed to buy out an entire floor of an apartment building just two blocks east of the Nicholson headquarters. But that also means one thing," Garrison turned to Recker, "Sergeant Recker, another CIA agent will be taking the reins again."

Recker heard Irish grumble, but Pac kicked him in the leg to keep Irish quiet.

Recker said, "His name?"

"Well, actually the person's a she this time. Her name is Special Agent Elsa Winters, and she'll be conducting this operation. She already has boots on the ground and has been conducting recon on Medved for the past two weeks. She'll brief you further when you arrive at the apartment building.

Irish couldn't hold it anymore, "But..."

Garrison knew what was coming if he allowed this to continue, "Irish, I'm not having this discussion. You will obey her orders, do you understand?"

"Yes sir." Irish sounded like a puppy dog that was just denied a treat.

"Anyways, all four of you will be deployed to Paris in an hour. And one last thing, and all of you need to look me in the eye on this one."

Everyone turned directly to face Garrison as he said, "Unless absolutely fuckin' necessary, do not blow your cover. And that's one thing I forgot to mention. You will be undercover for this mission, and your identities will only be known to Mr. Nicholson, his small security detail, and his family."

"Oo-rah," Pac said in agreement.

Turning to Hannah, Garrison spoke, "I'm glad you could join us on this mission Hannah, but you know you don't have to do this."

Hannah responded, "This will most likely be my last mission with Tombstone, but quite frankly, I'm honored to be working with you all."

"Thank you Hannah." Then Garrison turned to the rest of Tombstone, "Alright, make sure to gear up. Like I said, transport leaves in less than an hour. Dismissed."

After a minute or two, everyone had vacated the room except for Recker. He was looking at the two pictures of the CEOs of the world's biggest oil companies. He knew how much the US profited from Nicholson, and how much Russia profited from Medved. It would only take a spark, and Recker knew well enough what a spark could turn into. Recker examined Nicholson for a few seconds. The man was around 6 feet in height, and had auburn hair, a small mustache across his upper lip, light blue eyes, oval face, and a large nose. The man almost looked like someone familiar, but Recker couldn't pinpoint where. Looking at the other picture, Voronkov was slightly shorter than Nicholson. He had black hair, brown eyes, round face, small eyebrows and nose. But there was something shared between both men that Recker could infer from both pictures, and that was that they both looked like they had authority over the world, instead of having authority over a large oil company. But that wasn't for Recker to decide. All his mission consisted of was to protect Mr. Nicholson and his family, while also conducting intelligence on Medved Neftegazovyy. Recker knew this could potentially be dangerous, since it might even involve infiltrating the Medved HQ itself.

And then Recker remembered Agent Winters. He worried about how her interaction would be with the squad, especially with Irish. Even after watching Agent Kovic die before his eyes, he knew Irish still hated every single memory he had of Kovic, and Recker hoped for the best that Irish could get along with Winters. Remembering the time when Irish had hit Kovic with his machine gun, Recker cringed. I just hope our mission isn't compromised because of a poor interaction between Irish and a CIA agent. Hell, Irish probably mentally blacklisted all CIA agents as enemies. Who knows, but anyways, Recker had somewhere to be other than the briefing room. With uncertainty clouding his mind, Recker exited the briefing room to gear up in the tin can of a room he called his "second home."

A/N: Just as a heads-up, I plan to write this story from three points-of-view (the major ones), these being Dima Mayakovsky and Daniel Recker from the Battlefield franchise, and Elsa from the movie Frozen. And on that note, none of these characters belong to me, they all belong to the respective companies of DICE/EA and WDAS. All rights go to them. Anyways, next chapter will be an elaboration on Dima and his unit and as well as Tombstone meeting Elsa. And finally, there will be Russian and French spoken in subsequent chapters with English translations in parentheses. Thanks for reading, and be sure to leave a review!
