The scene opens up with Connor waking up on his bed as he put on his ECH-2 Combat Heads-Up Display System Helmet and his Advanced Modular Tactical Vest (AMTV), and it shifted to him in Seoul, until it shifts to him back in the camp, waking up Summer, before it shifted to him looking at Summer where he was hit on the chest by a sniper shot.

(This is what I'll use for the trailer, and I'm sorry if this insults the marines lol.)

It shifted to them waking up in a facility as Connor got off the table he was in, but he fell off where he got up and he went to Summer.

Connor: Sis. Sis, wake up.

It shifted to them at an abandoned city, moving in sync with each other as it was snowing and they were wearing their MCCUU Uniforms in Desert MARPAT. Easy targets, but they were moving through the abandoned vehicles in the city, and currently, Connor was armed with a URGI M4, while Summer had an HK416A5, which she got after her M27 IAR got replaced by it back in the facility. The URGI had a Trijicon MRO and an EOTech G33 Magnifier, a Magpul RVG Foregrip, a top mounted AN/PEQ-15 ATPIAL IR Laser, an Inforce WML Flashlight, and Gen M3 PMAGs as the entire rifle was in black, alongside all of the attachments, with the only thing left in FDE was the PEQ-15. But the 416 had a Trijicon TA31RCO ACOG, an FDE PEQ-15, KAC Vertical Front Grip, the Inforce WML Flashlight again, and also Gen M3 PMAGs. And they also wore Exo Suits. Then later on, a UH-60 Black Hawk was seen hovering by a drop zone as it lands and then it showed Connor and Summer moving up to a position where they stacked up by a cliff as it showed T-Dolls: MG3, M1919A4, FN49, Mosin-Nagant, and M14 on the cliff, laying prone or on one knee, overlooking Executioner literally beating M4 by a cliff as Connor fired an M320 and the 40mm Round was seen flying until it shifted to a group of Sangvis T-Dolls as it explodes. Then it showed Connor covering Summer.

Connor: Cover me, I'm moving!

M4: Roger!

Connor runs and fired his URGI as he got to cover and he was joined by SOP2.

SOP2: No wonder why we're lucky to have you with us!

Connor: Lucky for the entirety of G&K to have two active Marines in their personnel.

Connor fired his URGI in Semi-Auto as it showed Summer firing her HK416 as she gets covered by a Marine with a MK46 MOD 1 and he runs toward cover, firing his MK46 as several other Marines take hits but only become wounded. Then it showed an M1C Vanguard being dropped by an MV-25 Tempest as it flew off and then UH-3X Venom IIs were dropping off both Marines and T-Dolls as it then showed an AH-1ZX Hydra flying towards three Jupiter Cannons, alongside another Hydra alongside it as they both fired their M197A1 Tri-Barreled Rotary Cannons at it. Then it showed Connor's URGI, now with an M320 Grenade Launcher mounted underneath it as he fired it at several SF T-Dolls and then he fired the M320. And then it showed Summer firing an M32A1 MSGL as they were supporting Negev Squad, a group of Israeli T-Dolls composed of Negev, TAR-21, Micro Uzi, and Galil. Then it showed AR-15 trying to blow herself up, until one AH-1ZX Hydra arrived, firing its M197A1 at the SF T-Dolls, but failing to kill Elisa as Connor pulled AR-15 up and he fired his M18 at two SF T-Dolls as he then saw a CH-530KX Mustang and he got inside as he placed AR-15 on a seat and fired his MCX and the helicopter lifted off and then it shifted to him holding onto one of the guardrails of a UH-80 Shadowhawk.

Pilot: We are going down, repeat, we are going down!

The Shadowhawk crashed, killing two pilots, and then Connor got up and fired his M18 at two KCCO Droids as he pulls AK-12 up and he grabbed his M4 off the ground as Summer took her HK416A5 and then it showed AN-94, AK-15, AK-12, RO, M4, SOP2, and AR-15 running with the two of them as they were with two M555 McMaster AR/AAV Lightweight Battle Tanks, or LWBTs. Then  it showed the two in Paldiski as they were fighting KCCO Captain Yegor and currently, when Summer was injured again, this clearly got Connor to snap and lose it, where he grabbed her HK416A5 off the ground and fired at his mech, then he grabbed a large piece of metal as he lifts it and the exo suit helped him as then he just threw it at the mech and he ran extremely quickly where he just ripped open the cockpit, and he tossed a piece of C4 inside as when Yegor tried to pull him in to take Connor with him, Connor pulled his arm, headbutts him and he jumped off the mech where he blew it up. Then it showed all of them posing in a photo as M4, AR-15, M16, SOP2, AK-12, AN-94, AK-15, RO, 45, 9, G11, and 416 all posing in a photo with Connor, Summer, and the rest of their squad. Composed of Sarah Meyers, Joshua Adams, and Daniel Stiles.

M4: Haha, I didn't know we'd be able to take a picture. And Connor, thanks for helping me cope with my depression.

12: And hey, you're welcome to have us fight alongside you.

M16: Even though I betrayed everybody and the MPs got me arrested, I gave myself a second chance, you know.

Summer: Hey, big bro! Remember the times where your little sis always got herself hurt?

Connor: You remember the times when your big bro got himself hurt? We're siblings, you know.

Meyers: Hey Lieutenant, thanks for letting Riley help with my leg wound back in Seoul. It's been while when I was eighteen.

Adams: I've already been taking a lot of kills with my MK46, and well, I don't blame you for letting me kick some ass.

Stiles: Too bad we lost Neesen, Mathers and Riley, but they'll be watching us up there.

Marine: Any of you gonna stop chatting and let the photo be done?

Connor: Whoops, sorry about that, actually.. Oh well. Everybody, get to position!

Marine: Alright. 3, 2, 1...

Everyone: Semper Fi!

The photo was taken once they all said the shortened motto of the USMC.
